Added more helper methods (they just never stop, do they?)
Moved some stuff around because I want my chaos to be sorted
Actually made the server and clients interactive in the way they're supposed to be
Added CBC to NetClient to prevent ciphertexts from leaking info to malicious third parties
Removed the old (built in) AES implementation in favour of my own
Added a static salt to the AES implementation to heavily discrourage rainbowtables
Renamed a variable
Implemented a custom AES function as "Rijndael128"
- Built in key derivation at the moment (PBKDF2-HMAC-SHA1)
- Added built-in string encryption/decryption
- All encryption functions compute the results using the underlying mathematical models instead of using tables, simply to demonstrate the inner workings of AES
Simplified some methods for readability and convenience
Removed unnecessary use of BigInteger
Replaced manually (and terribly) calculated Galois field arithmetic with Galois2 methods to make the code simpler and more understandable
