hmac-sha1-final

Arguments: context &key return

This function, while still supported, is out of date.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.

Compute and return the HMAC-SHA1 checksum from context, an integer of length 128 or less. hmac-sha1-init returns a context, in a format determined by the return keyword argument.

return can be one of the following values:

• :integer (the default): the return value is an integer (typically a large integer) representing the digest.
• :usb8: return an usb-8 array containing the digest.
• :hex: return a string containing the hexadecimal representation of the digest. See hex-string-to-integer.

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