localStaticPrivateKey - The local static private key to use.localEphemeralPrivateKey - The local ephemeral private key to use.remoteStaticPublicKey - The remote static public key to use.remoteEphemeralPublicKey - The remote ephemeral public key to use.
CryptoTokenException - Thrown if an error occurs with a crypto
token of the crypto token is invalid.
CryptoUnsupportedOperationException - Thrown if a call is made to
an unsupported operation.
