All Implemented Interfaces:

Comparable<SASLMechanism>

Direct Known Subclasses:

ScramSha1PlusMechanism

public abstract class ScramPlusMechanism
extends ScramMechanism

SCRAM-X-PLUS implementation. Due limitations of the Java API, this mechanism only supports the 'tls-server-end-point' channel binding type. But on the other hand, the other relevant channel binding type 'tls-unique' has some flaws (see 3SHAKE, RFC 7627).
