This message digest program works like a checksum program. It takes a file and produces a 20 byte fingerprint of that file. You can use this program to compare files and to verify that files haven't been altered. Download rmd160.tar.gz .
Documentation is included.
Examples First, let's obtain the message digests for a few files in a directory. Now let's append a line to one of the files and see if rmd160 detects the change. The command line interface and output format for rmd160 is based on md5sum from the GNU textutils collection. Last modified January 12, 1997. Copyright information is available.
