# Password Management

For Generating password hashes, see [[password.hashes]]

Password management is a critical role for any sysadmin. These four functions can help you with password management.

Append these lines at the end of ~/.profile:

    # Generates a new random password 80 chars in length
    function newpass {
           jot -rc -s _ 80 33 127
    }
    # Generates a new alphanumeric password 80 chars in length
    function alnumpass {
            cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w ${1:-80} | head -n 1
    }
    # Pages through all your passwords
    function getpass {
            openssl aes-256-cbc -d -a -in $HOME/password.asc | less
    }
    # Writes all your passwords to ~/password
    function allpass {
            openssl aes-256-cbc -d -a -in $HOME/password.asc -out $HOME/password
    }
    # Takes your passwords in ~/password, encrypts them, then overwrites password.asc
    function savepass {
            openssl aes-256-cbc -a -in $HOME/password -out $HOME/password.asc && rm -P $HOME/password
    }


To use the functions, first source the file:

    $ . .profile


Afterwards, type the function in the command line:

    $ newpass
