Authors:

class Cipher [abstract] ¶

Base symmetric cipher class

uint update(const(void[]) input_, void[] output_) [abstract] ¶

Process a block of plaintext data from the input array and place it in the output array.

Parameters:

input_	Array containing input data.
output_	Array to hold the output data.

Returns:

The amount of encrypted data processed.

const(char)[] name() [@property, abstract] ¶

Returns:

The name of the algorithm of this cipher.

void reset() [abstract] ¶

Reset cipher to its state immediately subsequent the last init.

void invalid(const(char[]) msg) [static] ¶

throw an InvalidArgument exception

Parameters:

msg	message to associate with the exception

bool initialized() [final, const] ¶

Returns:

Whether or not the cipher has been initialized.

class BlockCipher : Cipher [abstract] ¶

Interface for a standard block cipher.

uint blockSize() [@property, const, abstract] ¶

Returns:

The block size in bytes that this cipher will operate on.

class StreamCipher : Cipher [abstract] ¶

Interface for a standard stream cipher.

ubyte returnByte(ubyte input) [abstract] ¶

Process one byte of input.

Parameters:

input

Byte to XOR with keystream.

Returns:

One byte of input XORed with the keystream.

class BlockCipherPadding [abstract] ¶

Base padding class for implementing block padding schemes.

const(char)[] name() [@property, abstract] ¶

Returns:

The name of the padding scheme implemented.

ubyte[] pad(uint len) [abstract] ¶

Generate padding to a specific length.

Parameters:

len	Length of padding to generate

Returns:

The padding bytes to be added.

uint unpad(const(void[]) input_) [abstract] ¶

Return the number of pad bytes in the block.

Parameters:

input_

Padded block of which to count the pad bytes.

Returns:

The number of pad bytes in the block.

Throws:

dcrypt.crypto.errors.InvalidPaddingError if pad length cannot be discerned.

struct ByteConverter ¶

Converts between integral types and unsigned byte arrays

struct LittleEndian ¶

Conversions between little endian integrals and bytes

T to(T)(const(void[]) x_) [static] ¶

Converts the supplied array to integral type T

Parameters:

x_	The supplied array of bytes (ubytes, bytes, chars, whatever)

Returns:

A integral of type T created with the supplied bytes placed in the specified byte order.

void from(T)(T input, ubyte[] output) [static] ¶

Converts the supplied integral to an array of unsigned bytes.

Parameters:

input

Integral to convert to bytes

Returns:

Integral input of type T split into its respective bytes with the bytes placed in the specified byte order.

struct BigEndian ¶

Conversions between big endian integrals and bytes
