WinMD5 for Windows 95

WinMD5 is freeware distributed by ING America, Inc. (www.ingamerica.com)

WinMD5 will create a message digest file for any file you select. The 
message digest file is created by default in the same directory as the
target file. WinMD5 will verify any message digest file and its 
corresponding target file. 

The message digest algorithm used is MD5, invented by Ron Rivest. The
message digest code used was written by Colin Plumb in 1993 with no copyright
claimed.  It has been tested against the RSA Data Security, Inc., reference
implementation, but does not use that implementation.  The MD5SUM main
program was written by Branko Lankester in 1993, and modified slightly by
Colin Plumb.  The getopt.c source code is public domain code from AT&T.
