Implementation

static final SignatureMethod hmacSha1 =
    SignatureMethod('HMAC-SHA1', (String key, String text) {
  final Hmac hmac = Hmac(sha1, key.codeUnits);
  final List<int> bytes = hmac.convert(text.codeUnits).bytes;

  // The output of the HMAC signing function is a binary
  // string. This needs to be base64 encoded to produce
  // the signature string.
  return base64.encode(bytes);
});
