HMAC.start

Reinitializes the digest, making it ready for reuse.

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.

struct HMAC(H, size_t hashBlockSize)

ref return

HMAC!(H, blockSize)

start

()

if (

hashBlockSize % 8 == 0

)

Return Value

Type: HMAC!(H, blockSize)

A reference to the digest for convenient chaining.

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);
hmac.put(data1.representation);
hmac.start();                   // reset digest
hmac.put(data2.representation); // start over
