androidjava中的三重DES算法

我不熟悉Android Java。我在C#中有以下用于加密（三重DES）的函数

我已经尝试了以下代码，以便在Android平台上使用相同的加密功能：

public static String EncryptText(String message) throws Exception {
        MessageDigest md = MessageDigest.getInstance("SHA-1");
        byte[] digestOfPassword = md.digest(secretKey.getBytes("utf-8"));
        byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);

        SecretKey key = new SecretKeySpec(keyBytes, "DESede");
        Cipher cipher = Cipher.getInstance("DESede");
        cipher.init(Cipher.ENCRYPT_MODE, key);

        byte[] plainTextBytes = message.getBytes("utf-8");
        byte[] buf = cipher.doFinal(plainTextBytes);
        byte [] base64Bytes = Base64.encode(buf,Base64.DEFAULT);
        String base64EncryptedString = new String(base64Bytes);

        return base64EncryptedString;
}

但是，两种平台上的加密结果不同？如果有人能帮我指出Android功能的问题

提前感谢。

我写了下面的三重DES ECB模式PKCS5/7填充模式加密解密课程，它对我有效：
