1 ;;;; This file implements The MD5 Message-Digest Algorithm, as defined in
2 ;;;; RFC 1321 by R. Rivest, published April 1992.
4 ;;;; It was written by Pierre R. Mai, with copious input from the
5 ;;;; cmucl-help mailing-list hosted at cons.org, in November 2001 and
6 ;;;; has been placed into the public domain.
8 ;;;; $Id: md5.lisp,v 1.3 2003/05/04 19:12:26 kevin Exp $
10 ;;;; While the implementation should work on all conforming Common
11 ;;;; Lisp implementations, it has only been optimized for CMU CL,
12 ;;;; where it achieved comparable performance to the standard md5sum
13 ;;;; utility (within a factor of 1.5 or less on iA32 and UltraSparc
16 ;;;; Since the implementation makes heavy use of arithmetic on
17 ;;;; (unsigned-byte 32) numbers, acceptable performance is likely only
18 ;;;; on CL implementations that support unboxed arithmetic on such
19 ;;;; numbers in some form. For other CL implementations a 16bit
20 ;;;; implementation of MD5 is probably more suitable.
22 ;;;; The code implements correct operation for files of unbounded size
23 ;;;; as is, at the cost of having to do a single generic integer
24 ;;;; addition for each call to update-md5-state. If you call
25 ;;;; update-md5-state frequently with little data, this can pose a
26 ;;;; performance problem. If you can live with a size restriction of
27 ;;;; 512 MB, then you can enable fast fixnum arithmetic by putting
28 ;;;; :md5-small-length onto *features* prior to compiling this file.
30 ;;;; Testing code can be compiled by including :md5-testing on
31 ;;;; *features* prior to compilation. In that case evaluating
32 ;;;; (md5::test-rfc1321) will run all the test-cases present in
33 ;;;; Appendix A.5 of RFC 1321 and report on the results.
34 ;;;; Evaluating (md5::test-other) will run further test-cases
35 ;;;; gathered by the author to cover regressions, etc.
37 ;;;; This software is "as is", and has no warranty of any kind. The
38 ;;;; authors assume no responsibility for the consequences of any use
39 ;;;; of this software.
