Arguments: string &key start end external-format return
Using md5-init (which creates a context), md5-update (which updates the context with the argument string), and md5-final (which finalizes the hash), this function computes the MD5 hash for string.
The start and end arguments specify the portion of the string to be considered and the external-format argument specifies the external hashing of the string that will be used to update the context. start defaults to 0, end defaults to the length of string, and external-format defaults to the default external format. These arguments, along with string, are passed to md5-update.
The format of the result, just as for md5-final, is determined by the return keyword
argument. The possible values are :integer
,
:usb8
, and :hex
. See md5-final for information on these
values and the corresponding formats of the returned value.
cl-user(4): (md5-string "foo") ;; default return format :integer 229609063533823256041787889330700985560 cl-user(5): (md5-string "foo" :return :usb8) #(172 189 24 219 76 194 248 92 237 239 ...) cl-user(6):
An earlier version of md5-string only accepted the single keyword
argument :usb8-result
(which, when specified true,
produced a result equivalent to specifying ':return :usb8'). That
keyword argument is no longer supported.
See MD5, SHA1, HMAC, and RC4 support in miscellaneous.htm.
