Examples of com.nimbusds.srp6.SRP6ServerSession.step1()

com.nimbusds.srp6.SRP6ServerSession.step1()

Increments this SRP-6a authentication session to {@link State#STEP_1}.

Argument origin:

From client: user identity 'I'.
From server database: matching salt 's' and password verifier 'v' values.

@param userID The identity 'I' of the authenticating user. Must not be {@code null} or empty. @param s The password salt 's'. Must not be {@code null}. @param v The password verifier 'v'. Must not be {@code null}. @return The server public value 'B'. @throws IllegalStateException If the mehod is invoked in a state other than {@link State#INIT}.

    System.out.println("Client session step 1");
    
    SRP6ClientSession client = new SRP6ClientSession();
    
    User user = getUser("\t");
    client.step1(user.I, user.P);
  
    System.out.println();
    
    
    // Step 2

    BigInteger s = readBigInteger();
    
    System.out.print("\tEnter password verifier 'v' (hex): ");
    BigInteger v = readBigInteger();
    
    BigInteger B = server.step1(I, s, v);
    
    System.out.println();
    System.out.println("\tComputed public server value 'B' (hex): " + BigIntegerUtils.toHex(B));
    System.out.println();
