Aliases

CreateSubkeysFunc

alias CreateSubkeysFunc = BitArray[16] function(const(ubyte)[] key) pure

Pointer to a routine that generates the subkeys. The mixcrypt algorithm for example uses a custom routine.

ProcessBlockFunc

alias ProcessBlockFunc = ubyte[] function(const(ubyte)[] block, const BitArray[16] subkeys) pure

Pointer to a routine that processes one block (8 byte). The mixcrypt algorithm for example uses a custom routine.

Functions

createSubkeys

BitArray[16] createSubkeys(const(ubyte)[] key)

Creates 16 subkeys given the de-/encryption key.

decrypt

ubyte[] decrypt(const(ubyte)[] data, const(ubyte)[] key, size_t unencryptedSize)

* Decrypts data using a specific key. * * Calls decrypt2 with the subkeys function createSubkeys and * the process function processBlock. * * The input data must be a multiple of 8 bytes and the input key * must be exactly 8 bytes long. * * Params: * data = The data array to be decrypted * key = The key used to decrypt the data * unencryptedSize = The size/length of the unencrypted data. * The returning data will be truncated to this size if it has padding. * * Returns: An array of bytes containing the decrypted data * * See_Also: * decrypt2

decrypt2

ubyte[] decrypt2(const(ubyte)[] data, const(ubyte)[] key, size_t unencryptedSize, CreateSubkeysFunc ksFunc, ProcessBlockFunc processFunc)

* Decrypts data using a specific key. * * The input data must be a multiple of 8 bytes and the input key * must be exactly 8 bytes long. * * Params: * data = The data array to be decrypted * key = The key used to decrypt the data * unencryptedSize = The size/length of the unencrypted data. * The returning data will be truncated to this size if it has padding. * ksFunc = The function responsible for creating the subkeys * processFunc = The function responsible for processing one block of data * * Returns: An array of bytes containing the decrypted data * * See_Also: * decrypt

encrypt

ubyte[] encrypt(const(ubyte)[] data, const(ubyte)[] key)

Encrypts data using a specific key.

encrypt2

ubyte[] encrypt2(const(ubyte)[] data, const(ubyte)[] key, CreateSubkeysFunc ksFunc, ProcessBlockFunc processFunc)

* Encrypts data using a specific key. * * The input key must be exactly 8 bytes long. * * Params: * data = The data array to be encrypted * key = The key used to encrypt the data * ksFunc = The function responsible for creating the subkeys * processFunc = The function responsible for processing one block of data * * Returns: * An array of bytes containing the encrypted data * * See_Also: * encrypt

feistel

BitArray feistel(BitArray block, BitArray subkey)

Apply the feistel routine to a given block of data. Used by processBlock.

processBlock

ubyte[] processBlock(const(ubyte)[] block, BitArray[16] subkeys, int rounds)

Processes one block (8 bytes) of data.

processBlock

ubyte[] processBlock(const(ubyte)[] block, BitArray[16] subkeys)

ditto, except that rounds is fixed at 16.
