BLAKE2

BLAKE2 structure template.

It is recommended to use the BLAKE2p512 and BLAKE2s256 aliases. However, if you wish to use a custom digest size, this is the structure to use.

Example definitions for BLAKE2s-160:

alias BLAKE2s160 = BLAKE2!(BLAKE2Variant.s, 160);
auto blake2s160_Of(T...)(T data) { return digest!(BLAKE2s160, T)(data); }
public alias BLAKE2s160Digest = WrapperDigest!BLAKE2s160;

struct BLAKE2 (

BLAKE2Variant var

uint digestSize

) {

alias IV = B2B_IV;

alias inner_t = ulong;

alias IV = B2S_IV;

alias inner_t = uint;

@safe @nogc nothrow pure

enum blockSize;

void start();

void put(const(ubyte)[] input);

ubyte[digestSizeBytes] finish();

@safe @nogc nothrow pure

ubyte[32] key;

}

Aliases

IV alias IV = B2B_IV: Undocumented in source.
IV alias IV = B2S_IV: Undocumented in source.
inner_t alias inner_t = ulong: Undocumented in source.
inner_t alias inner_t = uint: Undocumented in source.

Functions

finish ubyte[digestSizeBytes] finish(): Returns the finished hash.
put void put(const(ubyte)[] input): Feed the algorithm with data. Also implements the std.range.primitives.isOutputRange interface for ubyte and const(ubyte)[].
start void start(): Initiate or reset the state of the structure.

Manifest constants

blockSize enum blockSize;: Digest size in bits

Variables

key ubyte[32] key;: Undocumented in source.

Parameters

var: BLAKE2 hash variation.
digestSize: Digest size in bits.
