Security work
- Rewrote Crypto.Encrypt & Crypto.Decrypt; Readability mostly.
- Removed SafePC bool and functionality; ultimately it caused no slowdown to have in-memory encryption.
- The rewrite of encrypt/decrypt made the code overall less cluttered, by removing the salt. It is now automatically generated, retrieved and used.
... and I think that's about it for the overhaul of Encryption/Decryption.
