- # 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.
- #
- # == Examples
- #
- # require 'digest/hmac'
- #
- # # one-liner example
- # puts Digest::HMAC.hexdigest("data", "hash key", Digest::SHA1)
- #
- # # rather longer one
- # hmac = Digest::HMAC.new("foo", Digest::RMD160)
- #
- # buf = ""
- # while stream.read(16384, buf)
- # hmac.update(buf)
- # end
- #
- # puts hmac.hexdigest
- #
- class HMAC < Digest::Class
-
- # Creates a Digest::HMAC instance.
