Thread: Aika Bin files encryption-decryption

If you don't understand simple algorithm, I can't help.
buffer - array of bytes;

buffer = buffer_value - ( byte from cipher table ( ECX value mod length cipher_table) + ECX value )

Incorrect. Should be:
buffer = buffer_value - ( byte from cipher table ( CL value mod length cipher_table) + CL value )
