I have talked recently about my pet project Yith Library. It's a free online password manager running live here. One of the cool features it has is that you can download a backup file with all your passwords, ciphered of course.
I have developed a command line tool to read the backups, it's called Yith Library CLI. Right now it only reads backup files, but someday it will be a complete command line client for Yith Library. Someday...That's a nice logo :D
