I have an Android backup that I am sure I am using the right password. I have exported the file, and trying to decrypt it with openssl:

openssl enc -d -aes-256-cbc -md md5 -a -in ./backup_carteira_2017

or

openssl enc -d -aes-256-cbc -a -in ./backup_carteira_2017

I fill in the password when prompted and it seems to decrypt as I don't get a "bad decrypt", however the output is not readable at all. Any password different from the right one throws a bad decrypt error.

Am I missing anything here?

The backup has been generated in Jun, 2017, not sure if this matters.

Regards,
