This is a small command line utility to (re)generate passwords based on a master key, a domain name (or any other "domain" identifier), and optionnaly a username.
With the single master key to remember, you can regenerate the same password from the same inputs (domain and username) so you do not have to remember them.
The master key is not stored anywhere (only in your brain, so you need to have a little bit of it after all), not passed as a command argument and never displayed so it will not show in bash history, logs, etc.
Generated passwords contains letters, capitals, digits and special characters. We use a custom bas64 encoding on top of a PKBF2/SHA256 hash to provide those features with satisfying variety.
Passwords are 43 characters long most of the time.
$ nobrain example.com Master key: [hidden] Domain example.com Your password vh8n0+BXrsTzckt.n08r41n-sEpQKfD0MKXtL1j2Jfs
example.com is just an arbitrary identifier. It is a good practice
to use the domain name of the website you need a password for, so you do not
need too remember if you used
"Example Site" …
But any of those will work, too.
Simply add the
-u <username> option.
$ nobrain example.com -u lud Master key: [hidden] Domain example.com Username lud Your password eeovoS9HN9P:L4CsXf+Atw!6SHYehBjfBV:T.15CFF:
Note that the output is different, because the username is added to the hash. Any change to the username will result in a different password, so any username will have its own password.
