Demonstrates how to decrypt a string that was previously encrypted using 256-bit AES encrypted where the result is encoded to a hex string.

    // Decrypt a string using 256-bit AES encryption.  The encrypted
    // data is passed as a hexidecimalized string.
    CkCrypt2 crypt2;
    crypt2.UnlockComponent("anything for 30-day trial");

    crypt2.put_CryptAlgorithm("aes");
    crypt2.put_KeyLength(256);
    crypt2.put_EncodingMode("hex");

    // We are going to call DecryptStringENC which returns a string.
    // If the string that was encrypted was represented in some non-ascii
    // character encoding, we'll need to know about it in order to
    // interpret the characters of the decrypted string correctly.
    // In this case however, the string we are decrypting is us-ascii,
    // so we can leave the Charset alone...
    //crypt2.put_Charset("us-ascii");

    // Generate a binary secret key according to the KeyLength.
    // The SecretKey property is a byte array that can be set
    // directly by passing a byte array equal in bit-length to
    // the KeyLength, or you can let the CkCrypt2 class generate
    // a binary secret key given a password string.
    CkByteData secretKey;
    crypt2.GenerateSecretKey("myPassword",secretKey);
    crypt2.put_SecretKey(secretKey);

    CkString strDecrypted;
    crypt2.DecryptStringENC("4D55BBE6DFA47582EA3BC95D1EA8BBD6",strDecrypted);

    // The output of this example is: "Encrypt This!"
    printf("%s\n",strDecrypted.getString());
