我有一个Base64编码的图像.在Java中解码它的最佳方法是什么?希望仅使用Sun Java 6附带的库.
我试图解决这个问题,但我从来没有找到适合我的解决方案.问题是我正在接受有关BASE64Encoder的警告.没有BASE64Encoder,有没有其他方法可以做到这一点?
代码:
public static String Encrypt(String Data) throws Exception
{
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.ENCRYPT_MODE, key);
byte[] encVal = c.doFinal(Data.getBytes());
String encryptedValue = new BASE64Encoder().encode(encVal); //Here is the problem
return encryptedValue;
}
public static String Decrypt(String encryptedData) throws Exception
{
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.DECRYPT_MODE, key);
byte[] decordedValue = new BASE64Decoder().decodeBuffer(encryptedData); //Another problem
byte[] decValue = c.doFinal(decordedValue);
String decryptedValue = new String(decValue);
return decryptedValue;
}
private static Key generateKey() throws Exception

BASE64Decoder decoder = new BASE64Decoder();
byte[] saltArray = decoder.decodeBuffer(saltD);
byte[] ciphertextArray = decoder.decodeBuffer(ciphertext);

并希望将其转换为org.apache.commons.codec.binary.Base64.我已经浏览了API,文档等,但我找不到似乎匹配的东西并给出相同的结果值.
