md5-final

Arguments: context &key return

Compute and return the MD5 checksum from context, an integer of length 128 or less. md5-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.

In an earlier version, the keyword argument to md5-final was named :usb8-result rather than :return and only two return modes were provided: :integer (with ':usb8-result nil') and :usb8 (with ':usb8-result t'). The :usb8-result is no longer supported.

cl-user(4): (setq c (md5-init))
#(1 35 69 103 137 171 205 239 254 220 ...)
cl-user(5): (md5-update c "foo")
cl-user(6): (md5-final c :return :usb8)
#(172 189 24 219 76 194 248 92 237 239 ...)
