digest/hmac.rb

An experimental implementation of HMAC keyed-hashing algorithm

Overview

CAUTION: Use of this library is discouraged, because this implementation was meant to be experimental but somehow got into the 1.9 series without being noticed. Please use OpenSSL::HMAC in the “openssl” library instead.
