Title: Invalid private key error Post by: Tofee on December 07, 2022, 03:56:05 AM I am a novice as far as bitcoin is concerned. I lost my priv keys few years back and recently found while going through old lap top. However, I am unsuccessful as When trying to import private key in Bitcoin core v0.23.0 I'm getting:Invalid private key encoding (code -5). Private key starts with 5 and has total 51 digits.
I have created blank wallet in bitcoin-qt and encrypted with passphrase. I request your help. Thanks Title: Re: Invalid private key error Post by: Charles-Tim on December 07, 2022, 04:07:28 AM If the private key starts from 5, it supposed to be 51 characters, the characters are correct, but I do not know if the private key is valid, it can be invalid from typing error.
Maybe you do not get the right format of importing it. Read this: https://bitcoin.stackexchange.com/questions/5941/how-do-i-import-a-private-key-into-bitcoin-core. If not solved, Bitcoin Core users would be able help. Title: Re: Invalid private key error Post by: Tofee on December 07, 2022, 04:25:50 AM Thanks for your reply. I have strictly followed all the points mentioned in that post but still I am getting the error. I don’t have a clue. Let me know if I am missing any other points. Thanks

Thanks First check the validity of your priv. key on bitaddress.org . On the website go to wallet details tab and import the key in a plain text format. If it returns a valid bitcoin address, your key is correct otherwise some letters might be wrong. The error code you just mentioned usually occurs when one or more letters in the priv. key is invalid, might be a human error from your side.Title: Re: Invalid private key error Post by: NeuroticFish on December 07, 2022, 05:30:21 AM First check the validity of your priv. key on bitaddress.org .

OP, beware and make sure you don't enter the private key anywhere online. That's the recipe for disaster (ie getting your keys stolen). If you want to make this kind of tests, learn to get the source and open it in an offline (and safe) environment. My guess is also that you've probably mistyped something or confused some letters. Title: Re: Invalid private key error Post by: ABCbits on December 07, 2022, 12:13:50 PM Few suggestion,
1. Check whether all character on your private key is in Base58 symbol chart, https://en.bitcoin.it/wiki/Base58Check_encoding#Base58_symbol_chart (https://en.bitcoin.it/wiki/Base58Check_encoding#Base58_symbol_chart). 2. If you copy the private key, be careful you may copy invisible character which cause the error. On a side note, which software did you use to generate private key? Very old or unpopular wallet software may have implementation bug (such as wrong checksum calculation when generating WIF). Title: Re: Invalid private key error Post by: Tofee on December 07, 2022, 01:21:05 PM Thanks to all who replied. I appreciate your help and concern.
This key was received on purchase of bitcoins via PayPal about a decade back. Then, there was very little knowledge sources available online. I presume more than 400 attempts has been made to hack my bitcoins. Since the privkey has not been activated for many years, is there any possibility of keys invalidity? Also, can anybody suggest me what needs to do if few of the digits in privkey are not in base 58 table. I shall check Base 58 table and retry. Thanks to all. Title: Re: Invalid private key error Post by: NeuroticFish on December 07, 2022, 01:30:31 PM This key was received on purchase of bitcoins via PayPal about a decade back. Then, there was very little knowledge sources available online. This sounds like a scam to me. Only you should know the private key, since that's the only "thing" that allows spending coins. If the seller also knew the private key then: * there's a high probability he gave you from start a bad/invalid key * if by chance the key was good, there's a good chance that meanwhile the seller has checked back and spend those coins/sent them to his own wallet. When you buy bitcoin you should get your own wallet (if you are not knowledgeable about this and it's a meaningful amount of bitcoin then you should use hardware wallet) and give the seller an address of yours where he will send the coins. The coins are really yours only if they (are confirmed and) show up in a wallet only you can spend from = only you have the private keys. Since the privkey has not been activated for many years, is there any possibility of keys invalidity? Sorry, that's not how bitcoin works.

At least that's what I understand how you bought it. You shouldn't buy private keys from anyone, that is an unsafe method of transfer. Title: Re: Invalid private key error Post by: 2double0 on December 07, 2022, 06:11:11 PM Why buy private keys when you can get one with a wallet?
Is it like you bought it from some dark web source to get an 'advantage' of some Bitcoins in it as advertised by some dark web seller? Don't go for such deals if that's the case. And if you are skeptical about your wallet being a part of a possible hack, why not move your coins to a different wallet?

I proceeded with PayPal payment link and purchased with credit card. Little did I know anything at all except reading the white paper. After payment process, I received an email which stated to store the private keys in a safe location and to destroy the email. All the above happened more than a decade ago. So I thought that having private key is the confirmation and final step of the purchase. I was not aware that I need to have a wallet address and confirm the delivery. My fault is my loss.

Instead they will usually keep it in an "exchange account" for you and you have to withdraw it to your own wallet software.

Yes, you are right. Bitcoins was not worth even Pennie’s in those days. More over since the internet speed was in kb, hardly mining was worth. My case was in earliear days when people never gave any value to bitcoins. News spread about people loosing their assets only after MTGox was hacked.

Is there any possibility of finding the date of modification of the Base58 symbol chart omitting certain characters exclusive for use of bitcoin private keys and the corresponding version of the bitcoin core to that effect, as few characters in the keys not existing in the chart. Title: Re: Invalid private key error Post by: BlackHatCoiner on December 08, 2022, 07:37:04 PM Then I searched google how to buy bitcoins and those days it was a link which directed me to coinpal with PayPal link. Your story sounds very strange, and you must have been victim of fraud. First of all, CoinPal didn't give private keys. No legitimate business does. CoinPal, as far as I've read, was a service which asked you to submit a Bitcoin address, pay the Paypal invoice, and have the bitcoin received. Secondly, there's no way a legitimate business told you to "destroy the email". Emails from large email-corps don't get deleted either way, they sit on the email server's just in case. Have you deleted those emails? There's a chance you used a fake CoinPal site.

What makes you think that and how did you come up with that number? Why 400 and not 200 or 500?Hi, i see that you may need extra assistance you can contact me here: xxxxxxxxxxxxx Never under any circumstances share any sensitive information with this person or anyone else who contacts you privately. Do not click on any links or believe promises of magical software that will recover your coins just like that. Discuss the problem in public only. This does not apply to the FinderOuter software that nc50lc mentioned. I am only talking about things people could send you in private.CoinPal was a legit service back in the days, but it didn't work the way you described above. You can take a look at this YouTube video (https://www.youtube.com/watch?v=YmPg4V-YE0k) to see how the purchases used to work. The one thing CoinPal used to send to its customers via email is a transaction ID that could be entered into a blockchain explorer to check the transaction data online. But they didn't send private keys. Title: Re: Invalid private key error Post by: Tofee on December 11, 2022, 08:20:31 PM Thanks for the response and advice.The one charecter that does’nt fit the Base58 chart is ‘I’.

Sorry, it's quite funny that you're always coming-up with assumptions like the "400 hack attempts" and now "Bitcoin used to have different Base58 characters".I understand that thinking the latter is normal if you do not know Bitcoin's history. But the former... do the address in question perhaps shows 400+ inbound transactions in blockexplorers? Because that's normal for old dormant funded addresses, people tend to send dust to them for variety of reasons, but none for hacking attempt.

So if bitcoin qt does the same (not sure if it does) then create a new wallet, uncheck descriptor, wallet and import the keys into that new wallet as you cant use the importprivkey with a descriptor wallet afaik. looking more at your error message it might not be that though. worth a try i suppose either way easy enough to test.

Don't go for such deals if that's the case. And if you are skeptical about your wallet being a part of a possible hack, why not move your coins to a different wallet? do well to reread the message again before you make your contribution. You're wrong, read this OP's reply. This key was received on purchase of bitcoins via PayPal about a decade back. Then, there was very little knowledge sources available online. But just to give you an insight into what ops is asking, he said he want to recover his old bitcoin core wallet that he just recovered the private keys from an old computer but the wallet root is responding to an error message, which might be as a result of human mistake . Also wrong, 1. Bitcoin Core 23.0 was latest version when OP create this thread. 2. OP wanted to recover key he bought about a decade ago, not old Bitcoin Core wallet file. I am obliged to all who responded to my post and thank everyone for your response. I also found another post of someone stating purchase of bitcoins in 2009-2010 and receiving an email with private keys, advising the email recipient to delete the email after storing the key at a safe place. ###https://www.Reddit.com/r/Bitcoin/comments/7de7fa/i_found_out_i_bought_bitcoin_in_2009/ ### posted by u/DarkSchneider78 .

Thanks Title: Re: Invalid private key error Post by: Romoe on December 19, 2022, 06:24:57 AM How did you find your private key? Did you find it in an old email? or Was it handwritten?
if it's handwriting You might write it down wrong at some point. The private key that starts with '5' and has total 51 Char is Uncompressed WIF private key pattern (https://learnmeabitcoin.com/technical/wif). This type of key always has a checksum in the last position to check that all characters of the key are correct. When you try to import the key and got 'Invalid private key', It may be caused by having some characters wrong. If you write it down no more than 3 character wrong. you can recover it with this python script below. Code: import base58 You can adjust the code above to suit your case. Hope this help.

P2PKH stands for "Pay-To-Public-Key-Hash", which is when you pay to the hash of that public key, and not the public key per se. When you send coins to an address, you pay to the hash of a public key. P2PK is not used anymore (while it's perfectly valid), because P2PKH is smaller in size, and therefore cheaper. 1. P2PK and its corresponding privatekey 2. P2PKH and its corresponding privatekey. From standard wallet software, P2PK was never available (and if it was, it wouldn't be recommended). P2PK was used in the early days, because the first Bitcoin binaries were coded such so that the coinbase reward was sent to public key. I don't believe there was a specified reason for this selection. For example, this transaction is P2PK: 0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098 (https://mempool.space/tx/0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098). (it is labeled as "P2PK". mempool.space usually puts the address there, and P2PK doesn't have an address, but a public key, so it leaves it empty) On the other hand, this transaction is a P2PKH one, which spends two P2PK outputs: 7940cdde4d713e171849efc6bd89939185be270266c94e92369e3877ad89455a (https://mempool.space/tx/7940cdde4d713e171849efc6bd89939185be270266c94e92369e3877ad89455a). If you didn't mine coins in 2010/2011, then your money are sitting in a P2PKH output. It is likely that it's an uncompressed legacy address, which requires a WIF private key that starts with "5".

P2PK was used in the early days, because the first Bitcoin binaries were coded such so that the coinbase reward was sent to public key. I don't believe there was a specified reason for this selection. For example, this transaction is P2PK: 0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098 (https://mempool.space/tx/0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098). (it is labeled as "P2PK". mempool.space usually puts the address there, and P2PK doesn't have an address, but a public key, so it leaves it empty) On the other hand, this transaction is a P2PKH one, which spends two P2PK outputs: 7940cdde4d713e171849efc6bd89939185be270266c94e92369e3877ad89455a (https://mempool.space/tx/7940cdde4d713e171849efc6bd89939185be270266c94e92369e3877ad89455a). If you didn't mine coins in 2010/2011, then your money are sitting in a P2PKH output. It is likely that it's an uncompressed legacy address, which requires a WIF private key that starts with "5". Thanks for your response. I received the private key by email which starts with 5 and has 51 characters. I tried to sweep the key in electrum standard legacy wallet but it gave ‘invalid key’ error. After several attempts to sweep the key in specter and sparrow legacy wallets, I received the same error. Then I tried Bitcoin core v 23.0 Bitcoin-qt blank wallet and again I get the error of ‘invalid key encoding - error -5’. As per advice from this forum members, I tried to repair the key with FinderOuter but the result came as failed. I tried Python script posted on this forum but that did not work. Yesterday, I was watching a YT video of Bitcoins in early days of 2009 to 2011 era and the presenter was speaking about P2PK and P2PKH. Since the keys was received in early 2011, I presume the keys belong to P2PKH address. I am trying to figure out which wallet would be able to recognize my keys and point me in the right direction. Once again, thanks for your prompt response. Title: Re: Invalid private key error Post by: BlackHatCoiner on December 23, 2022, 10:49:23 PM Thanks for your response. I received the private key by email which starts with 5 and has 51 characters. Can you write exactly what Electrum returns you during import? A private key is invalid if it either isn't correct WIF (e.g., doesn't start with 5, isn't 51 characters, checksum isn't valid etc.) or if it's outside the range of valid private keys (which is between 1 and a little less than 2^256 - 2^32).I tried to sweep the key in electrum standard legacy wallet but it gave ‘invalid key’ error. Provide some log (or just the specific Electrum error if it isn't just "invalid key"), and we can verify about it being inside the allowed range. Title: Re: Invalid private key error Post by: nc50lc on December 24, 2022, 04:16:00 AM -snip- Unfortunately, that has nothing to do with the private key's invalidity.Yesterday, I was watching a YT video of Bitcoins in early days of 2009 to 2011 era and the presenter was speaking about P2PK and P2PKH. Since the keys was received in early 2011, I presume the keys belong to P2PKH address. It's all about the script type of the transaction of which the P2PK may have incompatibility with some wallets like Electrum. The private key should work, still valid today, the issue would be failing to sync (find) the transactions if the outputs are P2PK. (Bitcoin Core will work just fine) P2PKH on the other hand are the common "legacy" transactions that we see today, there shouldn't be any issue syncing those. Title: Re: Invalid private key error Post by: o_e_l_e_o on December 24, 2022, 01:00:53 PM As far as the private key is I feel I have been scammed. The key is an invalid key. As per advice from this forum members, I tried to repair the key with FinderOuter but the result came as failed. Given that you say your private key starts with 5 and has 51 characters (as it should), then it sounds very much like that one or more characters in your private key is incorrect.Have you tried substituting every character in FinderOuter for a wildcard one at a time and running it? Beyond that, the next thing I would suggest would be to use btcrecover (https://btcrecover.readthedocs.io/en/latest/). It supports raw private key recovery. You would feed it your private key, along with telling it to search for x number of typos, and let it do its thing. Note that 3 typos gives around 220 billion possible combinations, while 4 gives around 2.6 trillion, so the process might not be quick (or even possible, if you have more typos than this).

Title: Re: Invalid private key error Post by: o_e_l_e_o on December 25, 2022, 09:21:28 PM It means that the checksum (the last 5-6 characters of the private key) are not valid and do not match up with the rest of the private key. In other words, you still have one or more errors somewhere and have not yet found a valid key.
Is this error showing up on btcrecover? Can you share exactly the command you are running? Does it give you that error immediately or does it perform a search first?

If you find it in an original email, it's high likely that it's a scam because it's wrong from the beginning. but if it in the text file you created, The mistake might be that you recorded it incorrectly, for example You may alternate lowercase letters with uppercase letters. (Base58 is case sensitive), The more mistakes you make,the more time it takes to find. It may take an hours to find valid key in 3 letters wrong. But for 4 letters wrong, It may take months or even years to find the valid key [Run on one simple CPU 24hr/day] In this case, I think the first thing to do is you should try to find the private key form your original email. Title: Re: Invalid private key error Post by: Romoe on December 26, 2022, 04:14:39 AM This python script below can create new valid checksum, It probably won't help much. But you should at least give it a try.
Code: import base58 I can create the code that specific on your case, but I need more information [ex. how many 'I' and 'l' in your key and Where is it located?]. May be a months or a years, If you tried every possible way but still can't find the valid key, contact me at telegram or email on my profile.

If it is showing up immediately, then it means FinderOuter is simply checking the string you have entered and telling you it has an incorrect checksum.

Thanks for your response. Wish you and all a very very happy New Year 2023. May year 2023 bring peace, prosperity and good health to all. Regarding the invalid key which I have is as follows. The result in FinderOuter is “finished fail”. The key has checksum error along with several characters not at the right positions. It starts with 5 but the second character is ‘F’ followed by other characters with two invalid Base 58 characters and checksum error which makes me understand that last four characters are not correct. So, in total the key has the atleast 7 characters wrong and could be more. I am frustrated because I purchased Bitcoins via PayPal with my debit card in 2010/11 and least expected to be scammed on Bitcoins then because they were not worth even Pennie’s as of early days. I tried to sweep key from the key produced by FinderOuter in Electrum but it results in ‘No count’ I feel the entire key is invalid. If anybody can help me to get contact details of Blackschneider78 who has posted on this forum of having purchased Bitcoins in 2011, via email/PayPal, please do. Appreciate your suggestions and advice.

There are a lot of red flags here which make me think this is a scam, from the "seller" sending OP a raw private key instead of making a transaction, through to the key containing invalid characters.

I strongly suspect OP has been scammed and there are no coins to recover, but we can at least try. you may be right. the only thing is this was back in like 2010. i'm not sure how people sold bitcoin back then. maybe it was accepted to just sell the private key and not actually send bitcoin to the person's address. obviously that seems like a really bad idea today and you would think it would seem like one to people back then too but they didn't have all the different wallets and things they do now. so i guess it was harder to create your own wallet/address. there is also the remote possibility that the OPs laptop got some data corruption and the private key is not correct due to that. that's probably very unlikely but i guess it is a remote possibility.Quote You can correct me if I'm wrong (since I've never used PayPal), but my understanding is that there is a time limit of 180 days to open a dispute.

Unfortunately, the seller has never disclosed to me the address of my purchase hence I don’t have any clue as to what I own or I need to take into consideration before engaging third party wallet recovery. Though it is prophesied that ‘Your private key - your bitcoins” - in my case I was in the impression that I can trust the seller because it was purchased with escrow as PayPal. Currently after recovering the key, I feel that the seller has taken advantage of my trust and executed his stealth scamming game by advising me to store the private keys at a secret or safe place and to delete the email.

I don't trust PayPal in the slightest, so I would never suggest either buying from PayPal nor using PayPal to buy from a third party.Quote The best way to trade bitcoin is via a good decentralized exchange which has a built in trustless escrow such as Bisq, using a fiat method which is not easy for one party to reverse. thanks for pointing out that service. never heard of it before but i think the problem with services like this (DEXs) is they typically have low volume which means if you want to buy any significant amount of btc ( or sell), you're going to get price slippage. as an example lets look at Bisq's order book: Code: Sell Offers coinmarketcap says the current bitcoin price is around $16,827 but even if you only wanted to buy $3000 or so worth of bitcoin, your average price in that case is going to sit around $17,250. the more you want to buy, the worse your average price will be too! someone is making a profit and it's not YOU. :o yes you can place buy limit orders the problem with that is no guarantee they will get filled and you put yourself at risk of the market moving against you and then your order is out there like a sitting duck.

This much is true, but if I was selling a large amount I would never go to the order book on a single platform and just start scooping up all the orders there.

In terms of reversibility, then yeah, really the only completely safe payment method is cold hard cash. Any electronic fiat method can ultimately be reversed, although some are obviously much harder to do than others, and with PayPal it is almost trivial to scam the other party. I generally stick to cash or bank transfers when trading peer to peer, and have never had a problem with someone trying to reverse a bank transfer, although I am quite selective with whom I choose to trade.

Once or twice, but only ever with another party whom I have traded with several times before and built up some trust and rapport with.The main problems with cash via mail are privacy and security. The bitcoin seller must obviously give an address, and from our discussions regarding how to anonymously receive a hardware wallet, that can be difficult to do without compromising your privacy. However, if you do have a way to anonymously receive packages, then this can be an extremely private way to sell, and can be completely anonymous for the bitcoin buyer. There is also the security of sending large amounts of cash through the mail, and how to verify that neither party is attempting to scam the other. Bisq have a great tutorial on how to do it as safely as possible here: https://bisq.wiki/Cash_by_mail. I still probably wouldn't pick it as a method with a first time trading partner, though.

This search will take a very very long time for completion.

You have three unknowns for the first character, and 58 unknowns for the character in the middle. Even assuming the worst case scenario of the checksum only being 5 characters, giving you another unknown character in the 6th from last position, then there are only 3*58*58 possibilities, since the last 5 characters don't need to be brute forced since they will be calculated from the rest of the key. This is only 10,092 possibilities, which can be searched in under a second.Title: Re: Invalid private key error Post by: Tofee on January 16, 2023, 01:34:50 PM Hence, in FinderOuter, I have last six unknown characters and one unknown character in the middle of the key as basic search.

Ripemd160 is not working and tests are not working. I assume the last seven characters on a private key is based on checksum then the search would have been 3*58. I tried it on FinderOuter but the search is 3*58*58*58*58*58*58*58*58. Ie 3=first character after 5. Than 58 for one invalid character. Then last seven characters for checksum ( 58 x 7 ). Had FinderOuter provisions for elimination of checksum and calculated only the main characters then the search for valid key would have been very simple. If the seller who emailed me the private key has given me a valid key. As one of the response stated that if the seller has scammed me then none of the above search efforts are of any use. Hence, currently the task is unpredictable. Thanks Title: Re: Invalid private key error Post by: Tofee on January 16, 2023, 02:29:05 PM Unfortunately, the seller has never disclosed to me the address of my purchase hence I don’t have any clue as to what I own or I need to take into consideration before engaging third party wallet recovery. You don't need to know an address in order to attempt to brute force. The checksum will only be valid for 1 out of every ~4.3 billion possibilities, meaning you can easily simply look up the address of any valid key that you find.Here is the statement I am curious about: None of this is relevant to you. It does not matter what type of wallet created the WIF private key you are trying to recover. It is either a valid WIF key, or it isn't. The only thing that might change is the locking script related to your private key, but you won't be able to even start thinking about that until you have successfully brute forced the private key.“On March 7, 2014, Mt.Gox Co., Ltd. confirmed that an old-format wallet which was used prior to June 2011 held a balance of approximately 200,000 BTC," the statement said.” As reported CNN money - https://money.cnn.com/2014/03/21/technology/mt-gox-missing-bitcoin/index.html. I am trying to locate the seller or the sellers who had the capability of selling bitcoins during the period 2009 to 2011 and the name a few of them arise are Mt.Gox and Coinpal. If X = Mt.Gox (exchange ) or wholesale provider. If Y = marketer or internet marketing links/blogs administrator or distributor If Z = purchaser or buyer. What if the selling system was designed that bitcoins would be sold by the exchange Mt.Gox X (first party) on an order placement basis by second party Y (person who is marketing through link advertisements on internet such as Yahoo finance and other blogs) to third party Z (third party is purchaser or me in this case) then in this scenario X is instructed for delivery of bitcoins by providing the access authority or Privatekey to Z ( delivery destination email address). In this above mentioned scenario, if I am the legal owner for accessing those bitcoins but by virtue if the privatekey provided by X without providing details explanation of how to execute the key and if it is not valid key then how am I going to own them. There are other arguments which arise apart from this as well. Please give it a thought of the scenario I mentioned above and please let me know your opinion. Critics are welcome.

Had FinderOuter provisions for elimination of checksum and calculated only the main characters then the search for valid key would have been very simple. 1. Checksum part for WIF private key starting with '5' is only last 5 character (Not 7) 2. If you assured that there are 2 Char wrong, So all possible valid key that can generated is only 3x58. ( = 174 key) 3. After convert those key to P2PKH address (BTC address starting with '1'),You can check all of that 174 address if it have balance or not. (It takes less than 1 minute in bitcoin blockchain inquiry API) All the above processes can be done with one python script Title: Re: Invalid private key error Post by: Tofee on January 24, 2023, 06:57:37 PM Quote I assume the last seven characters on a private key is based on checksum then the search would have been 3*58.

As per your response, in FinderOuter, I will have to include 5 x 58 in place of checksum. Accordingly, the search would be 2 (for missing chapters) + 5(for checksum characters) = 7 * characters. Unfortunately, I don’t have the python script you referenced. If you can, please send me the link. Thanks.

I can create it for you, but I need to known where the wrong position is. For example, 5JXB[]hvvfQaT7GxoN7BGicZST25uGhLJ5aK9y3SS3LL[]766tfaS, the wrong position is '5' and '44' I don't check this site often, Can you contact me in telegram? [Telegram: @Panadawn] |
