public String Encryption(String toEncrypt) throws Exception
{
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
EditText et = (EditText) findViewById(R.id.entry);
byte[] input = toEncrypt.getBytes();
byte[] keyBytes = "hello".getBytes();
// et.setText("in encryption");
SecretKeySpec key = new SecretKeySpec(keyBytes, "AES");
Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding", "BC");
// et.setText("in encryption");
cipher.init(Cipher.ENCRYPT_MODE, key);
et.setText("in encryption");
byte[] cipherText = new byte[cipher.getOutputSize(input.length)];
int ctLength = cipher.update(input, 0, input.length, cipherText, 0);
ctLength += cipher.doFinal(cipherText, ctLength);
// et.setText("in encryption");
// return "abc";
return cipherText.toString();
从我加粗的代码行(cipher.init(Cipher.ENCRYPT_MODE, key);
)程序不工作 - 我得到一个异常。这条线有什么问题?我试图基本上加密一个字符串,并用这个函数返回它。这个在android中的加密代码有什么问题?
尝试重新格式化,并且还包含异常的内容。否则,真的很难回答你的问题。 – 2011-02-09 23:53:57
