Android Base64编码和Apache编解码器解码

我们正在使用以下方法使用ANDROID Base64对字符串进行编码。

    public static String encrypt(String inputString, byte[] keyBytes) {
    Calendar cal = Calendar.getInstance();
    int mDay = cal.get(Calendar.DAY_OF_MONTH);
    // System.out.println("Day of month :::" + mDay);
    String encryptedString = "";
    Key publicKey = null;
    try {
        Random generator = new Random(mDay);
        int num = (generator.nextInt()) % 100;
        String salt = "WEER563784" + num;
        inputString += salt;
        X509EncodedKeySpec publicKeySpec = new X509EncodedKeySpec(keyBytes);
        KeyFactory keyFactory = KeyFactory.getInstance("RSA");
        publicKey = keyFactory.generatePublic(publicKeySpec);
    } catch (Exception e) {
        System.out.println("Exception rsaEncrypt:::::::::::::::::  "
                + e.getMessage());
        e.printStackTrace();
    }
    // Encode the original data with RSA public key
    byte[] encodedBytes = null;
    try {
        Cipher c = Cipher.getInstance("RSA");
        c.init(Cipher.ENCRYPT_MODE, publicKey);
        encodedBytes = c.doFinal(inputString.getBytes());
        encryptedString = Base64.encodeToString(encodedBytes,
                Base64.NO_CLOSE);
        System.out.println(encryptedString);
    } catch (Exception e) {
        System.out.println("Exception rsaEncrypt:::::::::::::::::  "
                + e.getMessage());
        e.printStackTrace();
    }

    return encryptedString;
}

生成的加密字符串正在使用以下方法在Android应用外部解密

public static String decrypt(String inputString, byte[] keyBytes) {
        String resultStr = null;
        Calendar cal = Calendar.getInstance();
        int mDay = cal.get(Calendar.DAY_OF_MONTH);
        Random generator = new Random(mDay);
        int num = (generator.nextInt()) % 100;
        String salt = "qqq" + num;
        PrivateKey privateKey = null;
        try {
            KeyFactory keyFactory = KeyFactory.getInstance("RSA");
            EncodedKeySpec privateKeySpec = new PKCS8EncodedKeySpec(keyBytes);
            privateKey = keyFactory.generatePrivate(privateKeySpec);
        } catch (Exception e) {
            System.out.println("Exception privateKey:::::::::::::::::  "
                    + e.getMessage());
        }
        byte[] decodedBytes = null;
        try {
            Cipher c = Cipher.getInstance("RSA/ECB/PKCS1Padding");
            // Cipher c = Cipher.getInstance("RSA");
            c.init(Cipher.DECRYPT_MODE, privateKey);
            // decodedBytes = c.doFinal(Base64.decodeBase64(inputString));
            decodedBytes = c.doFinal(Base64InputStream());

        } catch (Exception e) {
            System.out.println("Exception privateKey1:::::::::::::::::  "
                    + e.getMessage());
            e.printStackTrace();
        }
        if (decodedBytes != null) {
            resultStr = new String(decodedBytes);
            System.out.println("resultStr:::" + resultStr + ":::::");
            resultStr = resultStr.replace(salt, "");
        }
        return resultStr;

    }

我们正在遵循以下例外

javax.crypto.BadPaddingException: Decryption error

所以问题是

1）是否可以在Android外部使用ANDROID Base64.NO_CLOSE解密加密的字符串，我的意思是直接在IDE中？

2）在一篇文章中，我发现使用ANDROID Base64.NO_WRAP加密的字符串可以在Android env外部解密，这是正确的理解吗？

非常感谢您的提前帮助。

问候，阿米特
