## hmac-sha1-init

Arguments: key &key external-format

This function, while still supported, is out of date. See the new hmac-init, hmac-string, hmac-update, and hmac-final which handle additional digest algorithms.

hmac-sha1-init prepares and returns a context for use in subsequent calls to hmac-sha1-update and hmac-sha1-final. The context is initialized according to the key argument. key can be a string or usb8 array (i.e (unsigned-byte 8) array). If key is a string, it is internally converted to an usb8 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.
