com.bitbucket.thinbus.srp6.js.SRP6JavascriptServerSessionSHA256

All Implemented Interfaces:

Serializable

public class SRP6JavascriptServerSessionSHA256
extends SRP6JavascriptServerSession
implements Serializable

Wrapper of a server session matching the Javascript client session SRP6JavascriptClientSession_N1024_SHA256. BigInteger values are communicated as hex strings. Hashing is done as string concat of hex numbers. Does not include any session timeout logic on the assumption that can be handled by web server session logic.

Specification RFC 2945.
