Hey all,

After searching everywhere last night, I have found several solutions to a problem I am experiencing, which don't work (yet). My Multibit Classic wallet is quite old, from 2013, using version 0.5.15, and I cannot decrypt the wallet, it rejects the password.. Apparently a common problem with the classic?

I have several rolling backups, a number of encrypted files, and a .key file, yet none seem to get decrypted properly with the password. I have used OpenSSL without succes.

Another thing I tried is a python script called Multibit Recovery by one of the forum members here. With the password, I am getting the Pubkey but not the privkey, it then shows the following output:

Traceback (most recent call last):
  File "decrypt_multibit_classic_walletkeys.py", line 215, in
    wallet = load_wallet(wallet_file, get_password)
  File "decrypt_multibit_classic_walletkeys.py", line 172, in load_wallet
    print("Privkey: " + bitcoin.encode_privkey(privkey, 'wif_compressed'))
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/bitcoin/main.py", line 224, in encode_privkey
    return encode_privkey(decode_privkey(priv), formt, vbyte)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/bitcoin/main.py", line 237, in decode_privkey
    if not formt: formt = get_privkey_format(priv)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/bitcoin/main.py", line 217, in get_privkey_format
    bin_p = b58check_to_bin(priv)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/bitcoin/main.py", line 427, in b58check_to_bin
    assert bin_dbl_sha256(data[:-4])[:4] == data[-4:]
AssertionError

I am hoping someone can make more sense of this than I can? Some of my files give an incorrect password message, some do give me back the PubKey but always the same error above.
