我在Visual Basic中有一个加密的字符串。NET 2008，加密和解密的功能如下：
Imports System.Security.Cryptography
Public Shared Function Encriptar(ByVal strValor As String) As String
Dim strEncrKey As String = "key12345"
Dim byKey() As Byte = {}
Dim IV() As Byte = {&H12, &H34, &H56, &H78, &H90, &HAB, &HCD, &HEF}
Try
byKey = System.Text.Encoding.UTF8.GetBytes(strEncrKey)
Dim des As New DESCryptoServiceProvider
Dim inputByteArray() As Byte = Encoding.UTF8.GetBytes(strValor)
Dim ms As New MemoryStream
Dim cs As New CryptoStream(ms, des.CreateEncryptor(byKey, IV), CryptoStreamMode.Write)
cs.Write(inputByteArray, 0, inputByteArray.Length)
cs.FlushFinalBlock()
Return Convert.ToBase64String(ms.ToArray())
Catch ex As Exception
Return ""
End …我需要将下面的C#代码翻译成Java,但是,我找不到任何与C#的Rfc2898DerivedBytes和Rijndael相当的Java.
private static string Encrypt(string sData, string sEncryptionKey)
{
string str = null;
string str2;
try
{
Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(sEncryptionKey, 8);
Rijndael rijndael = Rijndael.Create();
rijndael.IV = bytes.GetBytes(rijndael.BlockSize / 8);
rijndael.Key = bytes.GetBytes(rijndael.KeySize / 8);
byte[] buffer = Encoding.Unicode.GetBytes(sData);
using (MemoryStream stream = new MemoryStream())
{
using (CryptoStream stream2 = new CryptoStream(stream, rijndael.CreateEncryptor(), CryptoStreamMode.Write))
{
stream.Write(bytes.Salt, 0, bytes.Salt.Length);
stream2.Write(buffer, 0, buffer.Length);
stream2.Close();
str = Convert.ToBase64String(stream.ToArray());
str2 = str;
}
}
}
catch (Exception exception)
{
System.out.println(exception.getMessage());
}
return …
