This walkthrough demonstrates how to use the Cryptography Application Block to check whether a previously generated hash matches the hash for some text.

To reproduce the demonstration

  1. Declare the appropriate variables and constants.
  2. Obtain the text from the user.
  3. Call the static CompareHash method of the Cryptographer class to obtain the hash, supplying the name of the configured hash provider to be used. This code assumes that the member variable generatedHash contains a previously generated hash for some text.
