Digest::MD4 Extension Version 1.0 This is a Perl5 extension interface to the RSA Data Security Inc. MD4 Message Digest algorithm. Documentation is in MD4.pm. To build the extension, unpack this distribution under the ext/ directory of your Perl source distribution, create the Makefile using 'perl Makefile.PL' and do a 'make', then 'make test', then 'make install'. Note that the MD4.xs file uses the "PROTOTYPES: DISABLE" facility which only became available in late betas pf perl 5.002. If you are using a version which does not support this then merely remove this line. The mddriver.pl script gives a simple example of how to use the routines. In particular 'perl mddriver.pl -x' will perform a quick test of the routines to see if they produce the expected output. The use of "make test" will perform a more comprehensive test. (WARNING: You should not run mddriver.pl directly in the MD4 directory when using dynamic linking as on some systems it will dynamically link to object files in the current directory which may not give the correct behaviour. This is believed to affect at least AIX and IRIX. A similar caveat applies to the direct use of the test.pl script). The module is known to work (using static or dynamic linking) on at least AIX, Solaris, HP-UX and IRIX. It should work on other "reasonable" UNIX-like platforms (for an unspecified definition of the word "reasonable" :-) Support is also provided for 64-bit platforms. This should be detected and handled automatically. See the entry for version 1.7 in the Changes of MD5 for further details. The Digest::MD4 module was based entirely on the MD5 module by Neil Winton, and the MD4 code is from RFC 1320.
