HMAC

Overload of HMAC to be used if H doesn't provide information about its block size.

@safe

struct HMAC (

size_t hashBlockSize

) if (

hashBlockSize % 8 == 0

) {

enum blockSize;

this(const(ubyte)[] secret);

HMAC!(H, blockSize) start();

HMAC!(H, blockSize) put(ubyte[] data);

DigestType!H finish();

}

Constructors

this this(const(ubyte)[] secret): Constructs the HMAC digest using the specified secret.

Members

Functions

finish DigestType!H finish(): Resets the digest and returns the finished hash.
put HMAC!(H, blockSize) put(ubyte[] data): Feeds a piece of data into the hash computation. This method allows the type to be used as an std.range.OutputRange.
start HMAC!(H, blockSize) start(): Reinitializes the digest, making it ready for reuse.

Examples

import std.digest.sha : SHA1;
import std.string : representation;
string data1 = "Hello, world", data2 = "Hola mundo";
auto hmac = HMAC!SHA1("My s3cR3T keY".representation);
auto digest = hmac.put(data1.representation)
                  .put(data2.representation)
                  .finish();
static immutable expected = [
    197, 57, 52, 3, 13, 194, 13,
    36, 117, 228, 8, 11, 111, 51,
    165, 3, 123, 31, 251, 113];
