Cryptographic Hash Algorithms Let You Detect Malicious Code in ASP.NET
Cryptographic hash algorithms produce fixed-length sequences based on input of arbitrary length. A given input always produces the same output, called a hash code. Using these algorithms, you can compute and validate hash codes to ensure that code running on your machine has not been tampered with or otherwise changed. ASP.NET provides a software mechanism for validating hash code fingerprints for every page requested by a client. In this article, the author shows how to use hash codes with ASP.NET applications to detect tampering and prevent malicious code from running when tampering is detected.
