As a special service "Fossies" has tried to format the requested source page into HTML format using (guessed) C and C++ source code syntax highlighting (style: standard) with prefixed line numbers and code folding option. Alternatively you can here view or download the uninterpreted source code file. For more information about "md5.h" see the Fossies "Dox" file reference documentation.

   26   Independent implementation of MD5 (RFC 1321).
   27 
   28   This code implements the MD5 Algorithm defined in RFC 1321.
   29   It is derived directly from the text of the RFC and not from the
   30   reference implementation.

   32   The original and principal author of md5.h is L. Peter Deutsch

   34   that follows (in reverse chronological order):
   35 
   36   1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
   37   1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
   38     added conditionalization for C++ compilation from Martin
   39     Purschke <purschke@bnl.gov>.
   40   1999-05-03 lpd Original version.
