sha1-final

Arguments: context &key return

Compute and return the SHA1 digest from context, an integer of length 128 or less. 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 a usb-8 array containing the digest.
• :hex: return a string containing the hexadecimal representation of the digest. See hex-string-to-integer.

cl-user(4): (setq c (sha1-init))
#(1 35 69 103 137 171 205 239 254 220 ...)
cl-user(5): (sha1-update c "foo")
cl-user(6): (sha1-final c :return :usb8)
#(11 238 199 181 234 63 15 219 201 93 ...)
