Description

wallet.aes.zip

I think there is an error the blockchain2john on changing old blockchain.info wallets to hash.
Please see attached files and paste it on offline blockchain wallet decrypter.
The password works on the decrypter but john or hashcat cannot find it.

Research direction

Start with the blockchain2john entry point and the attached wallet.aes.zip, then compare the generated hash with the linked offline decrypter and the referenced blockchain.info discussion. Done means John or hashcat accepts the converted wallet and can recover the password that works in the offline decrypter.
