Hi,

I translate some functionality written in jsnode,
which contains a crypto library.

Although there is some sha256 support in
phobos I think, they do not provide all functionality
I need to translate following two functions.
(Input and output is ubyte[])

Is there a library which supports the methods
similiar (createHmac, update)... ?

function hmac(key, msg) {
  var hash = crypto.createHmac('sha256', key);
  hash.update(msg);
  return new Buffer(hash.digest(), 'binary');
}

function sha256(msg) {
  var hash = crypto.createHash('sha256');
  hash.update(msg);
  return new Buffer(hash.digest(), 'binary');
}

Kind regards
André

I am using  https://github.com/pszturmaj/phobos/tree/master/std/crypto

fantastic, thanks a lot.

Kind regards

Keep an eye on this one: Botan in D, https://github.com/etcimon/botan

Should be finished in a couple weeks.

e.g. from the TLS module:

auto hmac = get_mac("HMAC(SHA-256)");
hmac.set_key(secret_key);
hmac.update_be(client_hello_bits.length);
hmac.update(client_hello_bits);
hmac.update_be(client_identity.length);
hmac.update(client_identity);
m_cookie = unlock(hmac.flush());
