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
cl-user(5): (md5-string "foo" :return :usb8)
#(172 189 24 219 76 194 248 92 237 239 ...)

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.

SeeMD*, SHA*, HMAC, and other message digest support in miscellaneous.htm. See also digest-string.
