Overview
HMAC-SHA1 is an HMAC (hash-based message authentication code), a type of message authentication code using a cryptographic hash function and a secret cryptographic key, generated by the SHA-1 hash algorithm.
It is implemented in FPC trunk revision 27319 of March 2014.
Example code: packages/hash/examples/hsha1.pp
// See some samples in: http://en.wikipedia.org/wiki/Hash-based_message_authentication_code
program hsha1;
{$mode objfpc}{$H+}
uses
HMAC;
begin
// for HMAC_SHA1("", "") = 0xfbdb1d1b18aa6c08324b7d64b71fb76370690e1d
WriteLn('Example 1: ', HMACSHA1Print(HMACSHA1Digest('', '')));
// for HMAC_SHA1("key", "The quick brown fox jumps over the lazy dog") = 0xde7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9
WriteLn('Example 2: ', HMACSHA1('key', 'The quick brown fox jumps over the lazy dog'));
end.
