All Implemented Interfaces:

SRP6IntegerVariable

public final class SRP6ServerPublicKey
extends AbstractSRP6IntegerVariable

SRP-6 Server Public Key (B).

This variable is computed as:

 B = k*v + g^b
 

where ^ is modular exponentiation modulo N.

Refer to the package docs for more info on notation used.

SRP6ServerPublicKey

public SRP6ServerPublicKey(SRP6IntegerVariable prime,
                           SRP6IntegerVariable generator,
                           SRP6IntegerVariable multiplier,

                           SRP6IntegerVariable serverEphPrvtKey)

Constructs a new SRP-6 Server Public Key from prime, generator, multiplier, verifier and server ephemeral private key.

Parameters:

prime - SRP-6 Integer Variable: prime (N)

generator - SRP-6 Integer Variable: generator (g)

multiplier - SRP-6 Integer Variable: multiplier (k)

verifier - SRP-6 Integer Variable: verifier (v)

serverEphPrvtKey - SRP-6 Integer Variable: server ephemeral private key (b)

Method Detail

bytes

public Bytes bytes(ByteOrder preferredOrder)

Description copied from interface: SRP6IntegerVariable

Returns this SRP-6 Integer Variable as a byte sequence in the preferred byte order.

The representation returned must be minimal. That is, all leading (or trailing, depending on the preferredOrder) zero bytes have to be trimmed.

Number zero is hence defined as an empty byte sequence.

Parameters:

preferredOrder - the preferred byte order of the byte sequence that represents this SRP-6 Integer Variable

Returns:

the byte sequence that represents this SRP-6 Integer Variable in the preferred byte order
