Generate rebuildable strong passwords
Oneliner overview:
domain_password == base62(sha1(master_password + domain_key))[:8]
Goal
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.
Install
With pip:
$ pip install -U virtualkeyring
Usage
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']: foobar@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:
$ vkr-key
This will use your hostname as domain key. You can also set your domain key in
~/.virtualkeyring.
