我的後端服務器基於.NET。 在服務器上有使用Rfc2898DeriveBytes加密Rfc2898DeriveBytes for java?
這是淨
的代碼public static string Encrypt(string clearText)
{
string EncryptionKey = "abc123";
byte[] clearBytes = Encoding.Unicode.GetBytes(clearText);
using (Aes encryptor = Aes.Create())
{
Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
encryptor.Key = pdb.GetBytes(32);
encryptor.IV = pdb.GetBytes(16);
using (MemoryStream ms = new MemoryStream())
{
using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))
{
cs.Write(clearBytes, 0, clearBytes.Length);
cs.Close();
}
clearText = Convert.ToBase64String(ms.ToArray());
}
}
return clearText;
}
我寫的客戶端JAVA。這是代碼
try {
String encryptKey = "abc123";
byte[] salt = new byte[]{0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76};
SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
KeySpec spec = new PBEKeySpec(encryptKey.toCharArray(), salt, 1024, 128);
SecretKey tmp = factory.generateSecret(spec);
SecretKeySpec secret = new SecretKeySpec(tmp.getEncoded(), "AES");
System.out.println("Key:" + Base64.encodeToString(secret.getEncoded(), Base64.DEFAULT));
String cleartext = "12345";
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, secret);
AlgorithmParameters params = cipher.getParameters();
byte[] iv = params.getParameterSpec(IvParameterSpec.class).getIV();
byte[] ciphertext = cipher.doFinal(cleartext.getBytes("UTF-8"));
System.out.println("IV:" + Base64.encodeToString(iv, Base64.DEFAULT));
System.out.println("Cipher text:" + Base64.encodeToString(ciphertext, Base64.DEFAULT));;
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (InvalidKeySpecException e) {
e.printStackTrace();
} catch (NoSuchPaddingException e) {
e.printStackTrace();
} catch (InvalidKeyException e) {
e.printStackTrace();
} catch (InvalidParameterSpecException e) {
e.printStackTrace();
} catch (IllegalBlockSizeException e) {
e.printStackTrace();
} catch (BadPaddingException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
我在java中得不到與.Net相同的結果。 服務器上的12345
的加密值爲dAQWIrbtHv/eDbu+4oJD0g==
。
雖然我得到tcvGLK5r99jt6PFLALpRfQ==
什麼是修復我需要申請?
你需要從Java中的PBKDF2中獲得IV,但是你總是生成一個隨機的IV。 –
@ArtjomB。你可以分享代碼嗎? – WISHY
如果你寫了所有的代碼,那麼你也可以進行更改?還是你只是複製並粘貼你的安全代碼? –
