-// A tweaked version of HMACSHA1 that is more than twice as fast as the one above.
-// After this, more than 80% is spent in SHA1.
-// Optimizations:
-// - Avoids using ByteArray/std::vector
-// - Uses openssl's SHA1, which is slightly faster
-// - Does 'xor' on word basis
-// - Passes return value as a parameter
