    Crysis 2 CryEngine 3 Crypto Toolkit

    Crysis 2 CryEngine 3 Crypto Toolkit by fairchild (www.360haven.com)
    ================================================== ===== version 1.1 ===


    After many hours of debugging Crysis 2 i realized no one else had made
    any program to decrypt / encrypt the "CRYe" encrypted files, so i created
    this little tool.

    It can be used to decrypt / encrypt any files from Crysis 2 as long as
    the first 4 bytes in the header are "CRYe". You can even convert savegames
    from different platforms if you wish.

    And YES! It's a console based application....


    Now enjoy! And give proper credits if used somewhere else!
