Strong domain-specific passwords generator
Generate rebuildable strong passwords
domain_password == base62(sha1(master_password + domain_key))[:8]
This utility script helps generate a set of rebuildable domain-specific strong passwords out of a single easy to remember master password and domain specific keys such as “login@host”.
The generated passwords are strong since they use 8 characters out of a 62 characters long alphabet (lowercase and uppercase letters + digits) that are not to be found in any dictionary.
You can always re-generate your passwords by taking the base 62 encoding of the sha1 hash of the concatenation of your master password and domain key.
$ pip install -U virtualkeyring
Use the interactive command-line tool vkr that should now be in your PATH, and type in you master password and domain key:
$ vkr master password: mysecret domain key [e.g. 'login@host']: email@example.com Your password is available in the clipboard. You have 10s to paste it.
To generate passwords with length larger that 8 chars, for instance for an ssh key passphrase:
$ vkr -l 20
To generate passwords for a specific alphabet:
$ vkr -a 42aAuUTt
Add your ssh key with virtualkeyring
Add a ssh key to your ssh-agent:
This will use your hostname as domain key. You can also set your domain key in ~/.virtualkeyring.
1.6 (2013-07-21): use xerox to copy password to clipboard
1.4 (2010-04-01): hashlib support. add vkr-key script
1.3 (2008-06-01): add factorized out password fetching from stdin (thanks to gawel)
1.2 (2008-05-16): add -l and -a parameters
1.1 (2008-02-16) use getpass to read the master password from the keyboard
1.0 (2007-11-10) initial relase
