Constructor Details

ServerKeyExchange

public ServerKeyExchange(BigInteger par1, BigInteger par2, BigInteger par3, byte[] hash)

Creates outbound message

Parameters:

par1 - rsa_modulus or dh_p

par2 - rsa_exponent or dh_g

par3 - dh_Ys for ServerDHParams; should be null for ServerRSAParams

hash - should be null for anonymous SignatureAlgorithm

ServerKeyExchange

public ServerKeyExchange(HandshakeIODataStream in, int length, int keyExchange) throws IOException

Creates inbound message

Parameters:

in -

length -

keyExchange -

Throws:

IOException

Method Details

toUnsignedByteArray

public static byte[] toUnsignedByteArray(BigInteger bi)

Remove first byte if 0. Needed because BigInteger.toByteArray() sometimes returns a zero prefix.

updateSignatureRsa

public static void updateSignatureRsa(DigitalSignature ds, BigInteger modulus, BigInteger publicExponent)

updateSignatureDh

public static void updateSignatureDh(DigitalSignature ds, BigInteger p, BigInteger g, BigInteger y)

verifySignature

public boolean verifySignature(DigitalSignature ds)

isAnonymous

public boolean isAnonymous()

Will return true if the signature is null since this is considered anonymous.

send

public void send(HandshakeIODataStream out)

Sends message

Parameters:

out -

getRSAPublicKey

public RSAPublicKey getRSAPublicKey()

Returns RSAPublicKey generated using ServerRSAParams (rsa_modulus and rsa_exponent).

Returns:

getType

public int getType()

Returns message type

Returns:
