Attribution notice for RunUO-Encryption
---------------------------
The client encryption support in ModernUO (Projects/Server/Network/Encryption/)
is based on protocol research and reverse engineering originally performed by
Sebastian Hartte (DarkStorm) for the RunUO-Encryption project.

His work identified:
- The login packet XOR cipher algorithm used by the Ultima Online client
- The Twofish + MD5 game packet encryption scheme
- The login key values for client versions prior to 6.0.5

The Twofish block cipher implementation used in RunUO-Encryption was a C# port
by Shaun Wilde, originally published at:
http://www.codetools.com/csharp/twofish_csharp.asp

ModernUO's implementation is a clean rewrite using modern C# (Span<T>, SIMD,
BitOperations) but the underlying protocol knowledge originates from
Sebastian Hartte's reverse engineering effort.
