==========================================================================
Deterministic password generator
Uses XORSHIFT64 Pseudo Random Number generator
Probably not cryptographically secure but useful nonetheless
All you need to store all your passwords is a root password and a small security key
You remember those two and the name of the password and you will always be able to get the same
password by running the program
==========================================================================Try
Root password = Ash921!
Security key = 827123
Password for google

Do you get 4f0c49edef1d04a7?
