Only the +Makefile is modified. +----------------------------------------------------------------------- +This directory contains source code for the MD5 message-digest algorithm. + +MD5.tar.Z is a compressed tar file of all the other files in this directory. + +"md5-announcement.txt" is the announcement from RSA Data Security that +MD5 is being placed in the public domain for free general use. + +"rfc1321.txt" is the RFC that describes in detail the MD2, MD4, and MD5 +message-digest algorithms. + +The *.[ch] files were taken exactly from RFC 1321. +I wrote a simple Makefile to build an md5 executable by default, +with targets for "test" (which implements the test in Appendix A.5 in the RFC) +and "clean". Running Makefile with no targets will build the "md5" binary. + +There is a typo in the RFC Appendix A.4 (mddriver.c). +Line 20 sets MD to "MD5" by default, but the code wants +MD to be set to one of "2", "4", or "5". +I put a -DMD=5 in the Makefile to mask this problem so that the +code itself remains unchanged from what is in RFC 1321. + +Ric Anderson, ric@Artisoft.COM, provided a bug fix to the timing test +code that caused a divide by zero aborts on a Sun sparc station-10 +running soalris 2.3. This fix to mddriver.c is the only change to the +code in RFC 1321 and corrects only a problem with the timing tests. +No change to the code that implements the actual checksum has been made. + +Ric has also provided a man page - "md5.1". A postscript version +of this man page is in "md5.1.ps" and a text version in "md5.1.txt". + + -- Jim Ellis (jte@cert.org) |
