Most security-conscious web sites provide a md5 checksum file for each downloadable file. Occasionally, you may also see a SHA1 checksum file (for the really paranoid).
SHA 1 stands for Secure Hash Algorithm 1. It is a newer, and safer hashing algorithm than md5. (For the geeks among us, md5 is 128-bit; sha1, 160-bit.)
Again, for Linux users, to compute a sha1 checksum for a file, enter
sha1sum /path/to/file
For Windows users, you need to install extra software. Luckily, digestit (the software mentioned yesterday) supports both sha1 and md5.
While md5 is secure enough, if a file you are about to download has both md5 and sha1 checksums, you may want to use the sha1.

Indeed, security is a major concern in nowadays computing network communication.
Peter, if you don’t mind; you may trash this comment from your blog if you feel I went overboard.
I would like to do a little advertisement for the company I am working for. If you are an enterprise application architect, security architect, development manager, I.T. security professional, developer interested in implementing solid message security protecting your enterprise web services, please visit http://www.layer7tech.com SecureSpan Solution supports encryption methods of AES 128bit, 192bit, 256bit, triple DES for SOAP and non-SOAP XML messages.
Yes, you can first develop web services, and then apply SecureSpan Solution on top to give you peace! Also, dynamically modify security assertions without modifying application source.
