The code posted in post #5 correctly calculates HMACSHA1. Your mistake is somewhere else. Are you decoding the key? It is base64 encoded.

Hash = one directional function. In this case it is used to verify the integrity of the original message. A bit like an extended version of checksum. It is not an encrypted version of the message.
