MAPLE

Maple Metamorphic Stream Cipher

Maple is a metamorphic stream cipher based off "HC256" stream cipher, modified the cipher to include metamorphic crypto logic unit (CLU) is based off Magdy M. Saeb's work in the field of metamorphic encryption: Stone Cipher, the metamorphism are units of uint8_t BYTE's occuring before the final xor function of the stream cipher.
