java.lang.Objectorg.pfsw.security.crypto.HashedString
public class HashedString
Container for a SHA hashed strings including salt for SSHA. Supports SHA-1 (160 bit) as well as SHA-2 (256, 383, 512 bit). SHA-2 224 bit is not supported before Java 8 or with a crypto provider explicitly added to the classpath.
