Overrides org.conscrypt.OpenSSLCipher.engineGetParameters.

Doc from javax.crypto.CipherSpi.engineGetParameters.

Returns the parameters used with this cipher.

The returned parameters may be the same that were used to initialize this cipher, or may contain additional default or random parameter values used by the underlying cipher implementation. If the required parameters were not supplied and can be generated by the cipher, the generated parameters are returned. Otherwise, null is returned.

Returns:AlgorithmParameters
