Authenticated and Encrypted Requests

If privacy has been activated, the content of the request is encrypted, using the DES encryption protocol provided by the Java cryptography extension (JCE) from JDK 1.4. The secure hash algorithm (SHA) and MD5 encryption protocols provided in JDK 1.2 are also used. The requests are decrypted and forwarded once the identity of the sender and the timeliness of the request have been established.
