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

To reproduce the demonstration

  1. Declare the appropriate variables and constants.

    const string symmProvider = "symprovider";
string stringToEncrypt;
string encryptedContentsBase64;

    'Usage
Const symmProvider As String = "symprovider"
Dim stringToEncrypt As String
Dim encryptedContentsBase64 As String

  2. Obtain the text from the user.

    stringToEncrypt = "Sample text";

    'Usage
stringToEncrypt = "Sample text"

  3. Call the static EncryptSymmetric method of the Cryptographer class to perform the encryption, supplying the name of the configured symmetric provider to be used.

    encryptedContentsBase64 = Cryptographer.EncryptSymmetric(symmProvider, stringToEncrypt);

    'Usage
encryptedContentsBase64 = Cryptographer.EncryptSymmetric(symmProvider, stringToEncrypt)
