Class HostKeyHelper

java.lang.Object
hudson.plugins.ec2.ssh.verifiers.HostKeyHelper
public final class HostKeyHelper extends Object
Helper methods to allow loading and saving of host keys for a computer. Verifiers don't have a reference to the Node or Computer that they're running for at the point they're created, so can only load the existing key to run comparisons against at the point the verifier is invoked during the connection attempt.
