Question

An operating system

_ a password for a given user, converting it into a representation that cannot be understood without the appropriate algorithm.

Answer 1

what exactly are you asking? if you're trying to find out what encryption a certain OS uses then Google is great or if you're trying to convert your own string using programming then what language?

If you use python then import hashlib and use the print function, example:

pass = hashlib.sha512(b"Password").hexidigest()

print(Pass)
