- Rename HashResult to EncryptedPassword to reflect its broader use - Use EncryptedPassword in methods that require the hash and the salt, instead of passing them as strings separately - Store EncryptedPassword as field in PlayerAuth; updatePassword() thus processes the entire data in the EncryptedPassword object
