Just to follow up on that last sentence, if you are going to keep the secret around and use it later to derive more keys, then you want to protect its secrecy. For this reason, the secret should be used as the key in an HMAC rather than placing it into an unpadded hash, since the HMAC has been proven to protect the secrecy of its key.
