Python KeySaver

This is a small tool to create random passwords and store them in a file (pwdic). A master password is used to encrypt the data. Technical details can be found in the source.

Dependencies

• python3.8 or newer
• argon2 pip install argon2-cffi
• msgpack pip install msgpack
• pyperclip pip install pyperclip
• tabulate pip install tabulate
• ntlib.fctthread from here

Usage

Start the script with python3 -i keysaver.py [<pwdic>] or ./keysaver.py [<pwdic>]. It will open or create an encrypted file <pwdic> where your passwords are stored.

After 5 minutes without interaction you have to enter the master password again.

A password expires after a random time between 400 and 600 days. In that case you will be asked if you want to change it or not.

Commands

The following commands are probably self-explanatory. name is the name of a password-line.

• add_pw_line(name)
• delete_pw_line(name)
• copy_pw_line(name): duplicate the pw_line
• move_pw_line(name): rename the pw_line
• edit_pw_line(name): modify additional informations
• list_pw_lines(keys=('description', 'username')): show names and info for all saved password-lines, keys=None will show all keywords.
• pw_info(name): show all information assigned to name
• show_pw(name, info=False)
• copy_pw(name, info=False)
• open_pw(name): open website if available and copy password to clipboard
• change_pw(name)

To change the master password call change_mpw().

Security

For a higher complexity of your password you can use method b'\x00\x02':

change_mpw(b'\x00\x02')
