This example is in response to this customer question:
I have a question do you have any method that will encrypt the file in memory and then write it to the file system.

    CkCrypt2 crypt;
    crypt.UnlockComponent("30-day trial");

    crypt.put_CryptAlgorithm("aes");
    crypt.put_KeyLength(128);

    CkByteData secretKey;
    crypt.GenerateSecretKey("myPassword",secretKey);
    crypt.put_SecretKey(secretKey);

    // Load the contents of a file into memory.
    CkByteData dataToEncrypt;
    dataToEncrypt.loadFile("chilkatDude.jpg");

    // Encrypt it...
    CkByteData encryptedData;
    crypt.EncryptBytes(dataToEncrypt,encryptedData);

    // Save the encrypted data to a file.
    encryptedData.saveFile("encryptedDude.dat");
