Class Inheritance
Imports
java.security.*, java.security.spec.AlgorithmParameterSpec, javax.crypto.*, javax.crypto.spec.*, sun.security.internal.spec.TlsPrfParameterSpec, sun.security.pkcs11.wrapper.*
KeyGenerator for the TLS PRF. Note that although the PRF is used in a number of places during the handshake, this class is usually only used to calculate the Finished messages. The reason is that for those other uses more specific PKCS#11 mechanisms have been defined (CKM_SSL3_MASTER_KEY_DERIVE, etc.).

This class supports the CKM_TLS_PRF mechanism from PKCS#11 v2.20 and the older NSS private mechanism.
