Crypt::RIPEMD160 Extension Version 0.04 Crypt::RIPEMD160 adcO "RIPEMD-160 message digest algorithm" CHGEUER ######################################################################### CHANGES: Crypt-RIPEMD160-0.04 now supports BigEndian architectures (thanks to Ken Neighbors) ######################################################################### INSTALLATION: This is a Perl5 extension interface to the RIPEMD-160 Message Digest algorithm. Documentation is in RIPEMD160.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 try a 'make test' and wait for performing all tests. ######################################################################### SOURCES: All files in doc/ and the rmd160.*-files are taken from a sample implementation of RIPEMD-160. see also the RIPEMD160-Homepage: http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html The wrap_160.*-files are wrapper-code to allow the user to add small pieces of data to the message digest and to have the same convenient API like MD5 and SHA give. The Wrapper-Code was written by Christian Geuer. The rest (RIPEMD160.pm, RIPEMD160.xs, typemap, test.pl and Makefile.PL) are stolen and modified from MD5-1.7 and SHA-1.1. Thanks to Neil Wilton and Uwe Hollerbach for writing this code. Thanks to Ken Neighbors who updated this module to support big-endian systems in April 2001. Enclosed his comments: I changed three files: RIPEMD160.xs, wrap_160.h, wrap_160.c In RIPEMD160.xs, the section commented /* Little Endian (1234) */ actually works for big-endian systems as well, so I deleted the section commented /* Big Endian (4321) */. In wrap_160.h I added a buffer called "data" to hold the unprocessed bytes. The buffer "X" is now only used to hold bytes for processing. In wrap_160.c I used a trick from hashtest.c (available at http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html) to do the correct byte-ordering. ######################################################################### ADRESSES: Christian Geuer-Pollmann: geuer-pollmann@nue.et-inf.uni-siegen.de Uwe Hollerbach: uh@alumni.caltech.edu Ken Neighbors: ken@nsds.com Neil Wilton: N.Wilton@axion.bt.co.uk ######################################################################### TEST-VECTORS: RIPEMD-160 test suite results (ASCII): * message: "" (empty string) hashcode: 9c1185a5c5e9fc54612808977ee8f548b2258d31 * message: "a" hashcode: 0bdc9d2d256b3ee9daae347be6f4dc835a467ffe * message: "abc" hashcode: 8eb208f7e05d987a9b044a8e98c6b087f15a0bfc * message: "message digest" hashcode: 5d0689ef49d2fae572b881b123a85ffa21595f36 * message: "abcdefghijklmnopqrstuvwxyz" hashcode: f71c27109c692c1b56bbdceb5b9d2865b3708dbc * message: "abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq" hashcode: 12a053384a9c0c88e405a06c27dcf49ada62eb2b * message: "A...Za...z0...9" hashcode: b0e20b6e3116640286ed3a87a5713079b21f5189 * message: 8 times "1234567890" hashcode: 9b752e45573d4b39f4dbd3323cab82bf63326bfb * message: 1 million times "a" hashcode: 52783243c1697bdbe16d37f97f68f08325dc1528 #########################################################################
