Class SRP6JavascriptServerSessionSHA1

java.lang.Object

com.bitbucket.thinbus.srp6.js.SRP6JavascriptServerSession

com.bitbucket.thinbus.srp6.js.SRP6JavascriptServerSessionSHA1

All Implemented Interfaces:

Serializable

public class SRP6JavascriptServerSessionSHA1
extends SRP6JavascriptServerSession
implements Serializable

Wrapper of a server session matching the Javascript client session SRP6JavascriptClientSession_N256_SHA1. 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.
