zgrf.crypto.desbroken

Broken Data Encryption Standard (DES) implementation.

From the author of grftool: > GRAVITY's DES implementation is broken in that it uses > a bitwise AND instead of a bitwise OR while creating the keyschedule > causing the keyschedule to always be 0x80 bytes of 0. Additionally only 1 round is being used when processing a 64 bit block.

Functions

createSubkeys BitArray[16] createSubkeys(const(ubyte)[] key): Creates 16 subkeys all of them being 0x00.
decrypt ubyte[] decrypt(const(ubyte)[] data, const(ubyte)[] key, size_t unencryptedSize): Decrypts data using the key 0x00. Key parameter is ignored.
encrypt ubyte[] encrypt(const(ubyte)[] data, const(ubyte)[] key): * Encrypts data using the key 0x00. Key parameter is ignored. * * Params: * data = The data array to be encrypted * key = Ignored. Should be empty * * Returns: An array of bytes containing the encrypted data
processBlock ubyte[] processBlock(const(ubyte)[] block, BitArray[16] subkeys): Processes one block (8 bytes) of data.
