如何解密使用以下函数加密的字符串?
private static byte[] salt = new byte[] { 23, 21, 32, 33, 46, 59, 60, 74 };
private static int iterations = 1000;
private static int cb = 32;
public static string GetEncrypt(string plainText)
{
Rfc2898DeriveBytes k = new Rfc2898DeriveBytes(plainText, salt, iterations);
byte[] data = k.GetBytes(cb);
return Convert.ToBase64String(data);
}
