一天中的好时光，我需要以某种方式将 bouncycastle 库连接到 android studio。如何才能做到这一点？我以前从未处理过一个。这是我需要这个库的代码：

Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
        byte[] input = "www.javaCODEgeeks.com".getBytes();
        byte[] keyBytes = new byte[]{0x01, 0x23, 0x45, 0x67, (byte) 0x89, (byte) 0xab, (byte) 0xcd,


                (byte) 0xef};



        byte[] ivBytes = new byte[]{0x07, 0x06, 0x05, 0x04, 0x03, 0x02, 0x01, 0x00};


        SecretKeySpec pKey = new SecretKeySpec(keyBytes, "DES");

        IvParameterSpec ivectorSpecv = new IvParameterSpec(ivBytes);

        Cipher c = Cipher.getInstance("DES/CBC/PKCS7Padding", "BC");


        System.out.println("input : " + new String(input));


        // encryption pass


        c.init(Cipher.ENCRYPT_MODE, pKey, ivectorSpecv);


        byte[] encr = new byte;


        int ctLen = c.update(input, 0, input.length, encr, 0); …
