Only these hash algorithms Proof Of Work coins can be ported at this time. Proof of Stake coins will require much more coding (http://www.peercointalk.org/index.php?topic=1751.15). We can make coins that use other hash functions as well. Hash algorithms that we have translated into Java: - mainly just putting together existing pieces of code Quark (Java and Native) Qubit X11 (Java code for the individual hash functions was already available, native). Skein Groestl Difficulty Adjustment Algorithms KimotoGravityWell (Java + Native/Java Hybrid) FrankoGravityWell (Java + Native/Java Hybrid) DarkGravityWave (all three versions) Freicoin method (used in Megacoin) PPCoin method (used in IFC) Variations of the Bitcoin method Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on November 17, 2013, 02:04:15 AM HashEngineering started aa copy/paste find/replace Android Wallet app creation service. Currently we limit out work to previously made wallets by fixing bugs and maintaining the code and providing user support.
While we don't create android apps from scratch, we understand the C++ source code that defines the parameters that uniquely identify each coin. These parameters include the hash functions, coin generation rules, the network protocols and ports, difficulty retargets, transaction fees, genesis block information, DNS seeds, checkpoints and even where to get data from the block explorers and exchanges. This information is moved into a slightly modified Bitcoin Wallet / Bitcoin Java Library source code that allows for easy porting of a proven wallet to a new coin. HashEngineering was created when there was a need to fix the digitalcoin android wallet to be compatible with the V0.2 and V1.0 forks. We were further inspired when the digitalcoin android wallet developer announced that the standalone android app (it doesn’t require an online wallet) would no longer be maintained. Therefore we decided to fork the Bitcoin Wallet (v3.22) and BitCoin Java Library (v0.11) to digitalcoin in such a way that the java source code could more easily be ported to other coins while requiring a minimal amount of changes. A few lines of code were taken from the Litecoin Wallet (no longer available on Google Play) for the scrypt hash functions. Currently the Bitcoin Client source and the Bitcoin Android Wallet source have the coin defining parameters sprinkled through out many C++ or Java files [Similar to the actual Bitcoin QT Client]. Our modification contains a Java class called CoinDefinition where all of these parameters are stored in one place. Code: public class CoinDefinition {The modifications to the Bitcoin Wallet code include sections such as this one that refer to the CoinDefinition: Code: public class MainNetParams extends NetworkParameters {After this there is still a lot of Find/Replacing of the coin names that must be done to finish the port. Since we began, we determined that we can reduce the amount of find/replacing by leaving all the bitcoin references in the code for page names, classes and methods. Only the text needs to be changed and the graphics need to be updated. What about Proof of Stake Coins? Proof of Stake coins will require more code to be added to the Bitcoin Java Library (which now as been done by two independent developers). Currently, the Android Bitcoin Wallet is setup as SPV - Simplified Payment Verification. The App does not download the entire blockchain with all data on every block like the standard desktop client. This is good for a mobile device, where bandwidth is at a premium. Certainly no one would want to download the entire blockchain of Bitcoin to their phone (140 GB). The Bitcoin android app only downloads the block headers (80 bytes) and then queries the other peers for other information on transactions. The block header contains several types of data, but for this discussion the important data is the difficulty. The Android Wallet will verify the difficulty of each block as each header is downloaded from the network. Most coin forks have to do with difficulty code changes so this is an important thing to check. A proof of work coin only has 1 type of difficulty per block, which is for the proof of work hash function. The problem with Proof of Stake coins is that a block may be a Proof of stake block or a Proof of Work block. Unfortunately, the block header does not contain the information to determine if the block is POS or POW. More information is needed and that is the first transaction of the block. The Bitcoin Java Library can be switched to a mode that downloads the full block information. There will be other code needed to check what kind of block it is (POS, POW). Other code will check to make sure the difficulty is correct for each block. Additionally, other information is required to verify the coin staking. This prevents the wallet from being a lightweight wallet. Fortunately, some are working to get around the above issues. One is for Peercoin. It works in a similar way as the Bitcoin Wallet, but it does not verify blocks or block headers in the app, but submits requests to verify to a centralized server using a getvalidhashes API in an ABE based block explorer. To date we have not been able to get this solution to work for other coins. We don't do servers and rely on the others to do that and they have yet to deliver. http://www.peercointalk.org/index.php?topic=1751.15 (links for source are here). Additionally a developer has created a Blackcoin Wallet, which uses a "Full Pruned" blockchain storage method. Java Library Source - https://github.com/janko33bd/bitcoinj/tree/blackcoinj Wallet Source - https://bitbucket.org/janko33/bitcoin-wallet-4.16 Coinomi can also be forked for support a POS coin, but that does require electrum servers. Looking at the APK file for the source code: 1. One can use a Java Decompiler such as: http://jd.benow.ca/#jd-gui-overview to open the .apk file. 2. Most of the code is in the classes.dex file. That can be opened by first extracting it using a Archive file viewer such as 7Zip () and then using this tool to convert it to a .jar file (https://code.google.com/p/dex2jar/downloads/detail?name=dex2jar-0.0.9.15.zip&can=2&q=). Then use the java decompiler from step 1 to look at it. Title: Re: HashEngineering - Android Wallet Creation Service Post by: muddafudda on November 17, 2013, 03:33:52 AM Interesting and will take a good look later. Sounds good.
Title: Re: HashEngineering - Android Wallet Creation Service Post by: ahmed_bodi on November 18, 2013, 12:14:48 PM nice work hash engineering! hopefully this means we can get numerous mobile options around for coins! the mods you've made is one of the reasons i switched to electrum for the dgc wallet since that is coded in the same manner
Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on November 20, 2013, 04:46:29 PM The digitalcoin Wallet coding is complete.
Title: Re: HashEngineering - Android Wallet Creation Service Post by: ahmed_bodi on November 20, 2013, 04:57:26 PM Great I'll fork it and create the required mods to make it us able for all coins
Title: Re: HashEngineering - Android Wallet Creation Service Post by: deeppurple72 on December 06, 2013, 04:31:40 PM Hello.
Is this the same DIGITALCOIN WALLET for ANDROID Currently on google playstore? The google playstore DGC wallet has an issue Using the WRONG exchange rate. Just wondering if your app is the same one on playstore Or not. If it is the playstore app, please fix the Incorrect exchange rate the app is using. Also, sometimes it takes a very very long time To find any peers and sync up the blockchain. Thanks. Title: Re: HashEngineering - Android Wallet Creation Service Post by: ahmed_bodi on December 06, 2013, 04:43:49 PM that is mine im in the process of updating it, thanks
Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on December 07, 2013, 04:42:32 AM Hello. Is this the same DIGITALCOIN WALLET for ANDROID Currently on google playstore? This is not yet the digitalcoin Wallet currently on Google Play. It will be soon! This updated version will fix several of the problems that exist with the version on Google Play. Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on December 07, 2013, 04:43:39 AM Thanks to input from ahmed_bodi, we will make the forking process even more simple as the process will require only a minimal amount of renaming.
Title: Re: HashEngineering - Android Wallet Creation Service Post by: defaced on December 21, 2013, 10:28:45 PM So far the one for FRK is working GREAT!
Title: Re: HashEngineering - Android Wallet Creation Service Post by: stink on December 23, 2013, 01:37:06 AM There is a FlorinCoin bounty out for a android wallet here: https://bitcointalk.org/index.php?topic=379134.new#new
Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on December 31, 2013, 06:08:56 AM So far the one for FRK is working GREAT! Thanks for the feedback. Anyone else want to join my crusade of developing android apps? It is one thing to fork the bitcoin wallet, another thing to keep up with the coin forks! Title: Re: HashEngineering - Android Wallet Creation Service Post by: stink on January 07, 2014, 03:20:48 PM So far the one for FRK is working GREAT! Thanks for the feedback. Anyone else want to join my crusade of developing android apps? It is one thing to fork the bitcoin wallet, another thing to keep up with the coin forks! I have a 5000 florin bounty out for a wallet on florincoin. Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on January 09, 2014, 06:45:58 AM I have a 5000 florin bounty out for a wallet on florincoin. Thanks for this information. I will consider this coin. I will need to do some research on Florin to see how difficult it will be to fork from digitalcoin. Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on January 10, 2014, 07:07:52 AM We found out that we were missing the Native Library for scrypt, which was slowing down the processing of the blockchain. Now syncing the blockchain is 20 times faster and it should use much less power!
Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on January 13, 2014, 06:40:32 AM The Franko Wallet has been released:
https://play.google.com/store/apps/details?id=hashengineering.franko.wallet The digitalcoin-wallet will soon be released on Google Play. Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on January 13, 2014, 06:43:17 AM I have a 5000 florin bounty out for a wallet on florincoin. Florin Coin uses transaction comments, which will require extra coding in the Transaction class. As it turns out someone else is working on a java project for a similar coin which will be of help. Title: Re: HashEngineering - Android Wallet Creation Service Post by: wtman on January 18, 2014, 03:31:31 AM How hard is quark?
Are you taking orders? Cost? Please pm Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on January 20, 2014, 03:16:36 PM Quark will be hard. It has six separate hashing functions, each of which need to be translated to Java. At this point, the blake function has been found in Java.
Title: Re: HashEngineering - Android Wallet Creation Service Post by: SpiryGolden on January 22, 2014, 01:41:20 AM Top notch service from HashEngineering !
Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on January 22, 2014, 04:31:57 AM Further information on Quark: Three of the 6 hash functions have been found in java. Can anyone find bmw, groestl or jh?
This would also apply to SecureCoin. Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on January 23, 2014, 06:45:02 PM We are working on using the checkpoint feature from bitcoinj.
This feature will eliminate the need to download the entire blockchain. The blockchain stored by the app need only be 1 week older than the oldest set of keys. The checkpointing feature works better with linear difficulty adjustment code (from Bitcoin and Litecoin). The Kimoto Gravity well requires extra coding. Title: Re: HashEngineering - Android Wallet Creation Service Post by: ahmed_bodi on January 24, 2014, 01:26:08 PM the dgc android wallet has been tested and is working well with old wallets. it'll get added to gplay in the following few nights

Another developer has joined the Hash Engineering Team, which may help with getting more android wallets done. We have just cracked the Quark hashing function in Java, making us the best Android Wallet Development Service in the world. Title: Re: HashEngineering - Android Wallet Creation Service Post by: Apocalipsis on February 19, 2014, 09:48:36 AM Hash Engineering Solutions is currently working on the following android wallets. Our code base is currently bitcoin-wallet 3.30. We noticed that the Litecoin team has also forked this wallet and has added some of their own improvements. Current Project Status digitalcoin Android Wallet – The blockchain is synced and the forks for V0.2, V1.0 and V1.1 have been tested successfully. The other developer is testing some modifications to maintain backward compatibility with the previous litecoin version. https://github.com/HashEngineering/digitalcoinj (forked from https://code.google.com/p/bitcoinj - v0.12-SNAPSHOT) https://github.com/HashEngineering/digitalcoin-wallet (forked from https://github.com/schildbach/bitcoin-wallet - v3.31) Recent News: Not compatible with previous version of the digitalcoin-wallet because the previous version was forked from a buggy feathercoin fork that was saving its Private Key backups using the Bitcoin private key format. The other developer is working on a "fix". This app has been upgraded to 3.31 and is being tested.

This difficulty adjustment may work wonders for halting the strip mining of multipools, but it is not good for Android device battery long longevity or for sync speed with the blockchain.
There are three parts of the KGW code. The first part is the rewind (retrieving the previous block header), the second is difficulty calculation math with 256 bit integers and the last is some floating point math for other calculations. These three parts are part of a loop that repeats a certain number of times for each block. About half of the time involved in calculating the difficulty is retrieving the previous block information. Sometimes Megacoin needs to do this between 144 and 4000 times for each block. About 40% of the time is doing a subtraction, a division and an addition using 256 bit integers (Java BigInteger is slow). Lastly, the remaining 10% of the time is doing some floating point math. Currently, we are looking into getting the 256bit integer math handled Natively (machine code) instead of interpreted Java. Next will the the stepping back through the block chain.

Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on February 26, 2014, 11:12:06 PM How do we begin the process of having you guys make a TrollCoin Android Wallet? You can post a question in our forum and hopefully a developer will take on the job. Currently I am too busy to take on more work.Thanks! http://www.hashengineeringsolutions.com/forum/index.php?board=2.0 Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on February 26, 2014, 11:13:18 PM How difficult to add support Scrypt-jane and Scrypt-Adaptive-Nfactor? We don't have the answer for this right now as we haven't worked with these algorithms. Native support will be key. These hash functions really wear down the batteries of android devices. Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on March 04, 2014, 05:05:05 AM The Kimoto Gravity Well has been optimized (from Java to a Java/C++ hybrid) and now runs up to twice as fast.
It will be released in Megacoin and Franko soon. Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on March 14, 2014, 07:22:26 PM We have added native processing for the KimotoGravityWell to the Franko and Megacoin Wallets.
Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on March 20, 2014, 04:50:22 AM Many have requested wallets for new coins and others from older coins, but we do not have time to work on anymore than the five listed in the OP. We are currently trying to finish these apps and improve them in terms of speed (especially those that use the Kimoto Gravity Well) while updating from upstream (bitcoin-wallet upgrades and bug fixes).
However, we would be willing to make an exception to that rule if a coin has some innovative feature requiring java code that may not exist and the price is right. We will, however, continue to help other developers with questions on getting other coin apps running. We have helped up to four other developers. That is a good sign as there are perhaps 10 or more groups of developers out there that can do android apps, where 8 months ago there were perhaps only two. Good luck.

Howeve, that price is another way to say we are too busy to take on more projects. Wow.. 3 to 4 BTC is not cheap! Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on April 24, 2014, 05:36:56 AM Neither is it a quick thing to fork the bitcoin wallet to another coin. After that there is much maintenance required to keep the app functional given all the updates that coin devs push through.
Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on April 25, 2014, 06:30:17 AM We are currently considering working on Coins that use X11 and the Dark Gravity Wave. Someone has to write this code and it might as well be us.
As of today, we have successfully tested the X11 algorithm (in Java) and the Dark Gravity Wave (1 and 2). Nothing has been done on native versions of these for android, yet. Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on May 03, 2014, 06:12:25 PM Work has begun on the following coins:
1. Darkcoin - X11, Dark Gravity Wave - https://darkcointalk.org/threads/android-wallet.393/ 2. Myriadcoin - 5 concurrent hashing algorithms. These provide different challenges.

I am sort of stuck and looking for pointers. What I am trying to do is to take the schildbach wallet and customize it to my project. I am ctrying to make it work with a sha256 coin. No unusual settings, essentially a bitcoin clone :) By now I am pretty familiar with the QT wallet and I can make sense of the settings. In the android wallet I cant seem to find a file with peers or seed nodes. This may be a very silly question I get that... I am not terribly familiar with android so any help is appreciated. I can compile the schildbach code just fine, which I have done on numerous times to see what some of the variables do. What I suspect is that I may be looking for the wrong thing and that the android wallet functions completely different.

Sure would like to get an Andriod wallet going for Ixcoin, it should be an easy one for you. Our work is nearly completed & shortly we'll have all the major builds out for win32/64, mac & linux PPA flavors equal to the 0.9.3 Bitcoin codebase level. Know your more than likely extremely busy, but would like to attack the problem of having a version that runs on an Andriod and have not really started the process of figuring out what needs to be done. Perhaps you could easily do it, for me it will be a totally new learning experience. Haven't really looked into what issues would be involved, any pointers would be greatly appreciated or feel free to address the community @ large and the Ixcoin Foundation in our ToDo thread here: https://bitcointalk.org/index.php?topic=230141.0 (https://bitcointalk.org/index.php?topic=230141.0) Thanks much, GR Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on November 09, 2014, 07:26:47 AM I'm looking for an android wallet developer, but OP seems to have retired. I am very selective about what coins I do apps for at this time. I have made something like 7 apps and they do require a lot of time and then later updates based on how the coin developers modifiy the coin to try to handle various attacks or shortcomings. Myriadcoin had three forks in the past two weeks. That took come time to translate and debug. The wallets that I updated recently include Darkcoin, digitalcoin and Myriad. While those are active, other coins such as Franko and Infinitecoin seem to have died. For instance the Franko app doesn't connect to any peers and is useless. Megacoin still works and Quark does too. I have a preference to work on established coins (they have been around for 6 months). If the price is right, then I may be willing to add another coin app to my list. 3 or more BTC is where the price is right.

I can't really say what the log is sayin because i had to disable the tests when i make a clean install (or do you mean something diffrent? - i am testing the wallet only on my phone). The difficultyfilter is quite the same like in bitcoin (a little bit faster) so i think it really could be the genesis block hash. There are 3 nodes connected and they are all showing the correct block height. Is the reset block chain deleting all data? The wallet hat more than a gig data (which is not normal) which is not removed by reset.

Hi hashengineering, i switched to your namecoinj as a template (github.com/rikski/namecoinj) and included the changes for my coin and now it starts downloading the chain. After some help from hexafraction and adjusting the difficultycheck it downloads up to block 10k and then it crashes. In the report it says that after generating a new BlockMergedminingPayload and reading the bytes it crashes. I though maybe it is due to the extra property refHeight of the coins transactions, but then it should have failed earlier i guess. So the increase block height for 9999 to 10k somehow seems to be the problem. - I am using maven to compile. Code: === application info === Title: Re: HashEngineering - Android Wallet Creation Service Post by: jk_14 on August 11, 2015, 09:13:20 AM Hi, HashEngineering I have not common problem, I suppose. I try to refresh Vertcoin wallet. There were forks with algorithm change. block number 208301: switch from n-scrypt to Lyra2RE block number 347000: switch from Lyra2RE to Lyra2REv2 So as expected - the original wallet stop at 208300 block. I do have fresh Java implementation of Lyra2REv2, but I haven't old one Lyra2RE (and it's not quite easy due to changes made inside the Lyra2 algo, too) So my workaround idea is trying to skip 208301 - 346999 period and make checkpoints via BuildCheckpoints after 347000 block (temporary relaxing 1 month grace period) so I made such temporary corrections: Code: // ./core/src/main/java/com/google/bitcoin/core/Block.java and: Code: // ./core/src/main/java/com/google/bitcoin/core/AbstractBlockChain.java (...and now I'm downloading blocks above block number 208300, what will take a while...) I have some issues with generating checkpoints file yet: Code: root@vps179585:~/vertcoinj/tools# /usr/share/maven/bin/mvn exec:java -Dexec.mainClass=com.google.bitcoin.tools.BuildCheckpoints How to solve it, and if such way of checkpoints file generation - will be OK?

Code: [ERROR] Failed to execute goal on project vertcoinj-tools: Could not resolve dependencies for project The problem seems to be that the vertcoinj.jar cannot be found in the online or the local repository . It should be solved by installing the dependency manually - (when you use maven) go to your vertcoinj folder - search for vertcoinj-0.11.jar - use the shell to cd into the directory - use something like: Code: mvn install:install-file -Dfile=vertcoin-0.11.jar -DgroupId=com.google -DartifactId=vertcoin -Dversion=0.11 -Dpackaging=jar -DgeneratePom=true - If there is a failure please fit the spelling according to your file. for the POW check: are there further changes you have made?

The first error is something I haven't seen, where "Failure to find com.google:vertcoinj:jar:0.11 in" occurs. I am not sure why this is happening, I would need to look at your code. Secondly, the idea of skipping the first Fork with checkpoints have some problems/issues: 1. bypassing the proof of work on that many blocks will leave the app vulnerable to getting on the wrong fork for any user that installed his app before the fork. There may be a way of getting around this by adding some hard coded checkpoints into vertcoinj (something I put in CoinDefinition.java). Even the checkpoints could end up on the wrong fork, since you are not validating any of the blocks. Additionally 2. For the people after the forks, they won't notice anything, assuming the checkpoints come out correctly. 3. Using native libraries may be a way around not having the java code, even for BuildCheckpoints.java - native libraries also speed up the execution of hashes and can decrease battery usage on the device. this something you should look into to make your app secure.

However the last block is always connected as orphan and then it crashes due to a failed difficulty check. Doing some debugging although the block is merged mined the program finds no merge mining info (mmBlock == null) and then it takes the childchainhash which is higher than target. It only happens with the latest block, do you had this problem or an idea what went wrong? Rik EDIT: We have a solution thanks again (The orphan blocks are missing the merged mining informations. I dont know why but the namecoinwallet always thinks the latest block is an orphan. It then iscard the mmm info and the diff. check fails- so we included the memi infos in orphan blocks).

I am thinking I would want something similar to Bitcoin wallet which takes a smaller amount of space and doesn't hold the entire chain, nor does it need to Stake.

This is a known issue. This wallet is based on Bitcoin Wallet and the Bitcoin Wallet developers removed the "Disconnect" feature because it never worked properly all the time. What the wallet will do is keep track of how often it is used. If it is not used often, then it will less often start itself and sync the blockchain. There are no plans to fix it as there is no known solution to the issue. For the Dash Wallet, I removed disconnect, then received many complaints. So I added it back in. Its possible that other developers who do these apps know what to do. I will check with the Dogecoin developer.

Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on October 14, 2017, 01:37:55 PM We don't do POS coins. That requires an external server running a special block explorer. To date none have provided me with a working block explorer to serve that function.

Unobtanium wallet for Android. I am trying to restore a backup file with the Unobtanium Wallet which was created by the wallet. When I try to restore, by opening the backup file with the app, I enter my password and get a success screen, but the UNO never appears in my wallet. Also, when trying to send UNO from the wallet it just doesn't work. Is there a way to get the private key / decrypt the backup file so that I can sweep the wallet into another wallet? Please help I'm very concerned. Title: Re: HashEngineering - Android Wallet Creation Service Post by: HashEngineering on October 19, 2017, 03:12:17 PM Hey guys. Unobtanium wallet for Android.

Please help I'm very concerned. This sounds like this app is not connecting to the UNO network, so it cannot determine your balance. Sending will not work either if there is no network connection. Currently my app is connecting to one peer, but it is not syncing the blockchain. DECRYPTING YOUR WALLET FILE. You will need a PC with openssl and git. And your backup file. You now have your backup file on your PC. Wallet backups are encrypted. Let's decrypt it using: openssl enc -d -aes-256-cbc -a -in unobtanium-wallet-backup-2014-11-01 > unobtanium-wallet-decrypted-backup It will ask you for a decryption password, which is your backup password. If it prints "bad password" you've got the wrong password, but if it doesn't print anything your password might still be wrong. We can only be sure by looking at the decrypted data. RECOVERING FROM PROTOBUF WALLET FORMAT We need wallet-tool from bitcoinj. First, in a working directory, let's get bitcoinj: git clone -b release-0.12 https://github.com/hashengineering/unobtaniumj.git Make sure everything is compiled and ready to go by using once: cd unobtaniumj/tools ./wallet-tool Now use wallet-tool to sync the wallet from your backup: ./wallet-tool reset --wallet=unobtanium-wallet-decrypted-backup ./wallet-tool sync --wallet=unobtanium-wallet-decrypted-backup --debuglog The sync process will take anywhere from a few minutes to hours. Wallet-tool will return to the shell prompt if its finished synching. Have a look at the wallet: ./wallet-tool dump --wallet=/tmp/bitcoin-wallet-decrypted-backup --dump-privkeys You can skip the sync to the wallet if you don't think you received any coins in new addresses since you made your last backup. The last command will dump onto the screen all your private keys and your seed (12 word recovery phrase). The phrase may be able to be used in other unobtainium software that can read BIP32 / BIP39 phrases. Good Luck.

When I run the openssl enc -d -aes-256-cbc -a -in unobtanium-wallet-backup-2014-11-01 > unobtanium-wallet-decrypted-backup it asks me for my password, as expected. Except when I enter my password it returns a string of bizarre symbols and an error message. The password is apparently wrong. Nonetheless this is the very password that works each time I open the backup file on my Android device with the Unobtanium Wallet. Does the Unobtanium Wallet convert/translate the password I've chosen into something else, something which would yield a success in openssl?
