Class EncryptionArtifactFactory

java.lang.Object

org.jivesoftware.openfire.spi.EncryptionArtifactFactory

public class EncryptionArtifactFactory
extends Object

Instances of this class will be able to generate various encryption-related artifacts based on a specific connection configuration. This implementation intends to centralize the implementation for generating the artifacts produced, which in earlier versions of the code-base was scattered (and duplicated) over various connection-type-specific implementations.

Throws:

UnrecoverableKeyException - if the key could not be recovered

NoSuchAlgorithmException - if the algorithm is not supported
