Old multibit.key file

[DefaultAn]

I found an old multibit.key file from oct 2013.  It contains two lines the first is 76 characters and the second is 52.

Is there any way to find out if this contains anything?

If the first line starts with "U2F" and looks something like this:

Code:

U2FsdGVkX18LSYm98B5HRgLWHgx35xMcsSpjjtdC9XG6iEYh9OC+vfyQA1fNmjEKs64cm/bntH7g
/AMeb5NNSEe9hzYAgp/DRvOR+GX9E95pGcl4Gb2AHGMyUfAww7uV

Then it is encrypted and you would need to know what the passphrase was that encrypted this file to be able to recover the key(s) that are stored in it.

Sorry for not replying sooner... I keep forgetting to check this old Multibit board from time to time... it seems with the increase in BTC value there are more and more old multibit users coming out of the wood work

Anyway... have you tried using the openssl method to decrypt the .key file?

Code:

openssl enc -d -aes-256-cbc -p -md md5 -a -in multibit.key -out newtest.txt

This command (on Linux, but you can also install openssl for Windows) will prompt you for the password and then decrypt the .key file (simply change the multibit.key part to match your .key file) and create the .txt file that contains the decrypted text:

This is my "key_test.key" file:

Code:

This is what happens when I run the openssl command in linux:



This is the contents of newtest.txt:

If you're getting garbage output, it sounds like the .key file might be corrupt
