Examples of sun.security.internal.spec.TlsRsaPremasterSecretParameterSpec

sun.security.internal.spec.TlsRsaPremasterSecretParameterSpec
Parameters for SSL/TLS RSA Premaster secret generation. This class is used by SSL/TLS client to initialize KeyGenerators of the type "TlsRsaPremasterSecret".
Instances of this class are immutable. @since 1.6 @author Andreas Sterbenz @deprecated Sun JDK internal use only --- WILL BE REMOVED in Dolphin (JDK 7)
