I believe this version was pre-256 and was hashed using MD5, I have managed to decrypt this file with OpenSSL, but now the file is some weird, non-human-readable format, a binary wallet file rather than plain WIF keys??

Looking at recovery guide provided by the author, i would guess you entered wrong password.

You now have your backup file on your PC. Wallet backups are encrypted. Let's decrypt it using:

Code:

openssl enc -d -aes-256-cbc -md md5 -a -in bitcoin-wallet-backup-testnet-2014-11-01 > bitcoin-wallet-decrypted-backup

It will ask you for a decryption password, which is your backup password. If it prints "bad password" you've got the wrong password, but if it doesn't print anything your password might still be wrong. We can only be sure by looking at the decrypted data.

The command specifically mentioned MD5 which should match your case. But it also mention possibility of entering wrong password without message "bad password".
