pgman is a program to manage and guard your all passwords
The security is based on GnuPG/PGP. And the decrypted data file is in plain text format, which is editable by hands.
pgman runs in a interactively way, you can add, edit, list passwords.
It's not very well tested, please backup you encrypted password file! But it's usable, I am using it, it works fine for me. Use it at you own risk.
pgman has only one file, which based on python-pyme, readline.
