java.lang.Object
de.das.encrypter.examples.CryptoServiceUser
All Implemented Interfaces:
DataReceiver, ActionListener, EventListener
public class CryptoServiceUser extends Object implements ActionListener, DataReceiver
This example requests a key from the Encrypter-X crypto service, encrypts an image, and writes it back encrypted to a file. The requested and used key is in memory only for a short time and only during use. After running this example, the encrypted file can be viewed using the Encrypter-X browser function.

The requirements for running this example are that the Encrypter-X is running on this or another machine, its crypto service is configured (port is defined), the Encrypter-X and this example know the same keyring, and this example knows the IP address of the crypto service's home (usually localhost="127.0.0.1").
