Function `std.digest.hmac.HMAC.start`

Reinitializes the digest, making it ready for reuse.


						
				ref HMAC!(H,blockSize) start() return;

Note

The constructor leaves the digest in an initialized state, so that this method only needs to be called if an unfinished digest is to be reused.

Returns

A reference to the digest for convenient chaining.

Example

import std.digest.sha : SHA1;
import std.string : representation;
string data1 = "Hello, world", data2 = "Hola mundo";
auto hmac = HMAC!SHA1("My s3cR3T keY".representation);
hmac.put(data1.representation);
hmac.start();                   // reset digest
hmac.put(data2.representation); // start over
static immutable expected = [
    122, 151, 232, 240, 249, 80,
    19, 178, 186, 77, 110, 23, 208,
    52, 11, 88, 34, 151, 192, 255];
writeln(hmac.finish()); // expected
