Class ServerComponentManager

java.lang.Object

com.maverick.sshd.components.ServerComponentManager

Direct Known Subclasses:

JCEServerComponentManager

public abstract class ServerComponentManager
extends Object

An abstract class that manages the components used by the SSH API. All algorithm implementations are obtained through a single provider. Two implementations are provided, the com.maverick.sshd.components.standalone.StandaloneServerComponentManager which uses internal algorithm implementations and the JCEServerComponentManager that uses the Java runtime JCE provider(s) algorithm implementations.

If both component managers are available on the classpath then the JCE version will be selected. Jar files have been provided that contain both:

• maverick-sshd.jar
• maverick-sshd-standalone-only.jar, standalone only
• maverick-sshd-jce-only.jar, JCE only.
