MD5 encryption examples

[Kenneth]

Hi,

I need an example on MD5 encryption.

In a ascii textfile I have a date in string format. I need
an example how to compute a hash value on the datestring
and another method to compare the two with each other.

TIA

/Kenneth

Kenneth,

If you want to use MD5 (or SHA-1) hashing, the easiest way would be to call
the HashPasswordForStoringInConfigFile method, which returns a bas64-encoded
hash value. e.g.:

// C# code
using System.Web.Security;
....
string base64HashValue =
FormsAuthentication.HashPasswordForStoringInConfig File
("1/2/2003 7:04 PM", "md5");

Then you can simply compare strings. If you want to keep the hashed value in
the byte array format (or want to do something more sophisticated), check
this example: [url]http://www.obviex.com/samples/hash.aspx[/url].
