oracle.security.crypto.core.DHKey
oracle.security.crypto.core.DHPrivateKey
*** For internal use only *** A Diffie-Hellman private key.
The Diffie-Hellman private key contains a DHParams
and the private key value x. The encoding is based on the PKCS #8 type PrivateKeyInfo.
Status: Provisional (may be changed in future releases.)
