My bitcoin address is in my profile page here https://bitcointalk.org/index.php?action=profile;u=325680

Since version 0.4.0 multibit classic wallet files are in a format called Google protocol buffer format (protobuf). Open a file with a .wallet extension in a hex editor and look for the following sequence of bytes 08 01 12 20. The next 32 bytes after that should be your private key in hex format. After you get your private key in hex format you can convert it to a normal format using an offline copy of the bitaddress website.

I tested this on an unencrypted wallet (one with no password) in multibit version 0.5.1.6 and it worked for me.

This is the hex editor I used, although any other is probably sufficient.

This is the bitaddress website. I advise you not to directly paste private keys into it.

https://www.bitaddress.org/

Instead look for this link at the bottom of the page and use it to download a zipped copy you can run offline.

This is my multibit wallet's address 1F84fkbMng6dJpGZmtycRbUe72B7XSYbeT shown on the right hand side of bitaddress. Every raw private key can convert into two different bitcoin addresses, which is why there's two.

You can import your private key into the wallet of your choice to get control of yours coins back. Electrum's a good choice.



Well thank you , but today my computer was hacked first time in my entire life . Probably one of two sources stealing bitcoins !

If it's encrypted you can still get the private key, but it's more complicated. These instructions should work.

Download this and extract it.

https://indy.fulgan.com/SSL/openssl-1.0.2k-x64_86-win64.zip

Put the extracted folder in your C: drive root folder.

Put your encrypted wallet file in the same folder.

Open the windows command prompt by selecting run as administrator.

Type the line below into it and press your enter key/

cd /openssl-1.0.2k-x64_86-win64

Type the line below into it, but replace Untitled.key with your encrypted key file's name and password with your password, then press enter.

openssl enc -d -p -aes-256-cbc -a -in Untitled.key -out Unencrypted.txt -pass pass:password

Open the newly created Unencrypted.txt file in notepad to get your private key.

In the example file below the private key is the bit in red.
