示例1: CreateDERForRecipient

            DerObjectIdentifier derob = new DerObjectIdentifier(s);
            byte[] keyp = IVGenerator.GetIV(16);
            IBufferedCipher cf = CipherUtilities.GetCipher(derob);
            KeyParameter kp = new KeyParameter(keyp);
            byte[] iv = IVGenerator.GetIV(cf.GetBlockSize());
            ParametersWithIV piv = new ParametersWithIV(kp, iv);
            cf.Init(true, piv);
            int len = cf.DoFinal(inp, outp, 0);

            byte[] abyte1 = new byte[len];
            System.Array.Copy(outp, 0, abyte1, 0, len);
            DerOctetString deroctetstring = new DerOctetString(abyte1);
