wouldn't it be nice to have a option in the install process to choose between "normal" and "portable" installation?

Greetz!

@bitcoinspot.nl

Good idea to have an option in the installer for 'normal' and 'portable' installs.
It would save the fiddling around copying files around.

I have added it to the future features list on the wiki:
https://github.com/jim618/multibit/wiki


RE: Two wallets that have the same bitcoins in.
Here is a how-to guide:

1.) How to see if two wallets are the same.
To work out if two wallets are copies of each other, you need to check whether the receiving addresses are the same.  
(There is one receiving address for each private key - it is these that allow you to spend.)
Steps:
1.1) Start MultiBit.
1.2) Compare the receiving addresses between the two wallets.   If they are identical then one wallet is a copy of the other.
1.3) If they are the same, choose the wallet that you want to get rid of.   Let us say it is a wallet called "MyExpensesCopy" that you no longer want.
1.4) Make a note of the file path for the "MyExpensesCopy" wallet. If you hover over the filename in the "Your Wallets" screen you get a tooltip with the full path.
1.5) Shut down MultiBit.

2.) Preparing an unwanted wallet for deletion.
2.1) Make sure MultiBit is shut down.
2.2) In your filemanager, go to where the MyExpensesCopy wallet is stored.
2.3) Rename the file "MyExpensesCopy.wallet" to "readyToDelete.wallet".
2.4) Rename the file "MyExpensesCopy.info" to "readyToDelete.info".

3.) Checking everything is ok and deleting the unwanted wallet.
3.1) Start MultiBit.
3.2) Your unwanted wallet will no longer appear in the "My Wallets" screen.
3.3) Check that the wallet you intend to keep is ok.  (It should be - this is just double checking).
3.4) If the wallet you intend to keep is ok you can safely delete the "readyToDelete.wallet" and "readyToDelete.info" files.

Is there any planning for some more advanced wallet-handling in the future ?
- like deleting or archiving a wallet from multibit ?

Thanks again for the swift replies!

Greetz from holland.

Hi bitcoinspot.nl,

Yes.   The main reason you cannot remove wallets in MultiBit is that until recently there has been no block chain replay.

Imagine you remove a wallet from MultiBit on Monday (but it is still on your disk).
On Tuesday you think - oh I just need to look at that again and open it up.

Because there has been a day's worth of blocks the "Monday wallet" needs to be refreshed with the day's worth of blocks.

Block replay is more-or-less working but needs a bit more work to be 100%.   Once that is rock solid it will be easier to remove wallets and then reopen them.

Deleting wallets (as in total destruction) would be doable now as it is just deleting the files.

Hi speedbus,

I have been working on ironing out a few bugs this week - the 0.3.0beta3 release I had to release a bit earlier than I wanted because of some network code that needed updating.

I should get a new release back to the normal quality by Monday so if you could hang on until then that would be good.
(Under the covers I have been updating to a much more recent version of bitcoinj so there have been a few things to sort out).

Bear with me.

Can you please fix the bug where Multibit won't connect or download the blockchain since 20/2/2012? I really want to move my BTC to the main client as the official client tends to be more stable thanks.

Let me know if it is not.

Yes - you just have to move the files multibit.wallet and multibit.info to your usb key. (The info file contains things like your address labels).   Just put them anywhere convenient.

You can also rename the multibit.wallet and multibit.info to, say MyCash.wallet and MyCash.info if you do not like the default name.  The prefix has to be the same on both files.

When you next open multibit you will see an autogenerated empty wllet with the name "multibit".   Just ignore that and go to "Open Wallet" and find your wallet you just moved and select it.   It should then appear on the "Your Wallets" page.

I've tested this and this works fine.For those of you having issues with blocks not downloading,please use Multibit V0.30 beta 3 to rectify the issue that cropped up from 20/2/2012 onwards.Thanks.

@film2240 - that is good to hear.   I think it is a good idea to have the bulk of your BTC on the Satoshi client as you are right it is more mature (and it has wallet encryption).   Please try out the Multibit updates from time to time to see it's progress though !   :-)

@speedbus - thanks!   I have got the newer version almost there - just testing it now.

@Nachtwind.  The installer for Windows is actually written in Java so if that runs you definitely have it one your system (which you also indicate with your comment).  

The multibit.exe searches for a copy of Java to run using this order:
<JVMSearchPath>registry</JVMSearchPath>   << Registry settings
<JVMSearchPath>javahome</JVMSearchPath> << JAVA_HOME environment variable
<JVMSearchPath>jrepath</JVMSearchPath>
<JVMSearchPath>jdkpath</JVMSearchPath>
<JVMSearchPath>exepath</JVMSearchPath>   << PATH environment variable
<JVMSearchPath>jview</JVMSearchPath>

I suspect either your registry settings or JAVA_HOME are pointing somewhere it does not expect.

You could try explicitly manually installing Java from:
http://www.java.com/en/download/help/windows_manual_download.xml

That might put in the correct registry settings which, as they are top of the list, the multibit.exe will look for first.

I have just been preparing screenshots for the main feature in the next MultiBit release:


Encrypted private key export files
These will enable you to safely transfer private keys from computer to computer and you can use them for wallet backup.

Here is the screen shot and how-to for the export:
http://multibit.org/help_exportingPrivateKeys.html

And here is the screenshot and how-to for the import:
http://multibit.org/help_importingPrivateKeys.html


OpenSSL compatibility
For maximum compatibility I have used the same encryption methodology as in OpenSSL so you can also encrypt and decrypt the files using the command line utility 'openssl'.

To decrypt an encrypted MultiBit private key export file use:
openssl enc -d -p -aes-256-cbc -a -in <ciphertext file> -out <plaintext file> -pass pass:<password>

To encrypt a plaintext MultiBit private key export file use:
openssl enc -p -aes-256-cbc -a -in <plaintext file> -out <ciphertext file> -pass pass:<password>


File specification and an example
The spec for the export files is pretty straightforward - it is basically just the private key in sipa wallet import format and its creation date.  More details: MultiBit private key export specification

Edit: here is the contents of an encrypted private key file for a single key:

U2FsdGVkX18qFcs9rcWzN2vFRqK/KgcHerb9aQkbVrr2UD60T/QOjMY+UlOLb8OWrPOX7fRzBF9s
ycM46QVERkoYOlZu/9dtwV2P/UFXk+W/tkTrxn/0ymWmQqsj8rZq

And here it is decrypted with the password 'jim':
5JiGQHkFCFiAictiaWx5LkKP4ZTPz4GZ8vF9KLQoc2itvRke8J2 2012-03-02T23:29:33Z

(I've taken the BTC out!)



The next release of MultiBit should be in a day or two - just got some testing and tidying to do.
