Arguments: digest-name key string &key (external-format :default) (return :integer)

The digest-name argument determines the digest algorithm. Supported digests are :md5, :sha1, :sha224, :sha256, :sha384, and :sha512.

hmac-string returns the hash value of string, given key. 'key' can be a string or usb8 array (i.e (unsigned-byte 8) array). If it is a string, it will be internally converted to a usb8 array according to the external-format keyword argument (or the default external format if the keyword argument is not supplied).

return determines the form in which the hash value will be returned. See the documentation for hmac-final for details.

See MD*, SHA*, HMAC, and other message digest support in miscellaneous.htm.
