Pass-gen is a light password generator. Having multiple passwords or even a password per service is usually a secure practice but it can get quite annoying to generate password for it.

This tool comes with different options:

• -l NUMBER : specify the length of the password. It is possible to use a range like N1-N2.
• -s STRING : specify the string that pass-gen should use to generate the password. In short, it is all the characters possible in the password. This option will always be override by the usage of -a, -ac, -sp, -nu.
• -n NUMBER : The number of password pass-gen will generate.
• -a : Use only alphabetical characters.
• -ac : Use only alphanumeric characters.
• -sp : Use only alphanumeric and a few special characters.
• -nu : Use only numeric characters.
