黑莓TripleDESEncryption輸出轉換成字符串

Question

我試圖加密使用TripleDESEncryption一個字符串，跟着這個例子中，我發現在互聯網上（鏈接：http://www.blackberry.com/developers/docs/3.6api/net/rim/device/api/crypto/doc-files/CryptoTest.html#sampleMD5Digest）：

// sampleTripleDESEncryption 
private static int sampleTripleDESEncryption(byte[] secretKey, byte[] plainText, byte[] cipherText) throws CryptoTokenException, CryptoUnsupportedOperationException 
{ 
    // Create a new Triple-DES key based on the 24 bytes in the secretKey array 
    TripleDESKey key = new TripleDESKey(secretKey); 

    // Create a new instance of the Triple-DES encryptor engine, passing in the newly 
    // created key 
    TripleDESEncryptorEngine engine = new TripleDESEncryptorEngine(key); 

    // Encrypt one block (8 bytes) of plainText into cipherText 
    engine.encrypt(plainText, 0, cipherText, 0); 

    // Return the block size of the engine 
    return engine.getBlockLength(); 
} 

不過，我想加密的數據轉換字符串。我不確定cipherText變量是否是要轉換的變量。任何幫助？我將如何轉換它？

Answer 1

你只是不希望結果將通過參數返回。

所以首先在chiperText中分配足夠的緩衝區。調用方法，你將得到返回長度（返回值）的緩衝區chiperText。
