This walkthrough demonstrates how to use the Cryptography Application Block to decrypt text.

To reproduce the demonstration

  1. Declare the appropriate variable and constants.
  2. const string symmProvider = "symprovider";
    string encryptedContentsBase64;
  3. Call the static DecryptSymmetric method of the Cryptographer class to perform the decryption, supplying the name of the configured symmetric provider to be used. The following code assumes the member variable encryptedContentsBase64 contains a string that was encrypted using the same symmetric provider.
  4. string decryptedContents = Cryptographer.DecryptSymmetric(symmProvider, encryptedContentsBase64);
