Usage

Generate a random password

Prints a random cryptographically secure password to the terminal

$ newpass

Generate a password from a SHA256 hash of a string

This option can be used to print a 'memorable' password to the terminal. Which is to say, the outputted password will always be the same if the passed in string is identical.

It requires a unique string longer than 8 characters with a mixture of upper and lower case, numbers and special characters. The password will always be the same if the passed in string is the same.

While this option uses SHA256 hashing, it is less secure than generating a random password.

$ newpass -s "Some unique string 123!"
