md5-string

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 calculates the checksum of the resulting context), this function computes the MD5 checksum for string.

The start and end arguments specify the portion of the string to be considered and the external-format argument specifies the external encoding 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.
