Arguments: digest key &key external-format
The digest-name argument determines the digest algorithm. Supported digests are :md5, :sha1, :sha224, :sha256, :sha384, and :sha512.
hmac-init prepares and returns a context for use in subsequent calls to hmac-update and hmac-final. The context is initialized according to the key argument. key can be a string or (unsigned-byte 8) array. If key is a string, it is internally converted to an (unsigned-byte 8) array according to the external-format keyword argument (or the default external format, if the keyword argument is not supplied).
See MD5, SHA*, HMAC, RC4, and other message digest support in miscellaneous.htm.
