Hi HCP,

Thanks for your reply, and your script! I ran your mod and it gives me a 94 character long output, which I guess it is not supposed to do. The error after that is:

Traceback (most recent call last):

When I run the script for the .key file, it tells me the password is incorrect. I was wondering about the password, but if it decrypts the PubKey correctly it must be the right one, right? I am afraid the .key and other files are corrupted? All the files I have give the same output btw, I have a saved file from when I installed Multibit, and one from after that. Another option I guess would be to decrypt the wallet.cypher files, I havent managed to do that with OpenSSL yet though, because it is more than 64 char, and my knowledge of it is little.

Would it be possible to decrypt the .wallet file and look at where the problem lies in the code? I have encoded and decoded a wallet file with the same password and name, which decrypted perfectly with your script! If I can put those decrypted next to each other, I might be able to spot the difference.

The output PrivKey I guess is wrong, but would it be decrypted correctly, just with a few to many characters?

I am using a mac btw
