compute hash value for a string

Cool, Alan !

I thought I should just add that the choice of methods depends on the level of security you need i.e. the lower the chance of producing a collision, the more secure the hash is.

String.GetHashCode() only produces a hash which is 32 bits long and so is not very secure.

In practice most people use the MD5 method (the one you mentioned) which produces a 128 bit hash or SHA1 which produces a 160 bit hash though both have been compromised in recent years.

For bullet-proof security, .NET also supports the SHA256, SHA384 and SHA512 algorithms.

Thanks Bechir Bejaoui,

 string oString = "Google";
            int hash = oString.GetHashCode();
            MessageBox.Show("OString hash code is : " + hash.ToString());
