Hyperion is a runtime encrypter for 32-bit and 64-bit portable executables. It is a reference implementation and bases on the paper "Hyperion: Implementation of a PE-Crypter".
Changes: Hyperion now rejects unsupported .NET executables, preserves the GUI/Commandline PE flag, has a lower AV detection because static stuff was removed, and 64 bit output file size was reduced by 4 kilo bytes.
