PBKDF2 Based Password Hashing

[Sephus]

PBKDF2 (Password-Based Key Derivation Function 2) is a key derivation function that is part of the PKCS #5 standard. It is used to derive cryptographic keys from a password. PBKDF2 applies a pseudorandom function, such as HMAC (Hash-based Message Authentication Code), to the input password along with a salt value and repeats the process many times to produce a derived key. This process makes it computationally expensive to perform brute-force attacks.

PBKDF2 was introduced in Horizon's newer releases for the safekeeping of passwords and user information. New commands were added in to the `auth` server along with this update - Command `reset-password <username> <password>` will reset the password for the given username. Command `create-account` will generate a hash for the given text password input in the command.
