RE: Authenticity of downloads

[jburzenski () americanhm com]

MD5 and SHA1 are standard hashing methods and there are (open source and
other) tools available on just about every OS for generating a hash.  I use
md5sum and sha1sum in linux.

Here is a way to do it with visual c# .net

There are some freeware tools on the web, just google for "md5 hash on
windows" and you'll see a bunch. 

Hope this helps.
