MD5

Command-line utility which computes and checks message digests (digital signatures) generated by the MD5 algorithm as defined by RFC 1321. This program is handy for software installation, file verification, and other system administration shell scripts and Perl programs. Includes complete C source code for Unix and a ready to run Win32 executable. New version 2.0 adds multiple file signature generation (including wildcard expansion in the Win32 version), tagging signatures with file names, and optional lower case letters in hexadecimal output.
