asp.net c＃中的加密和解压缩 [英] encrption and decrption in asp.net c#

问题描述

有什么方法可以像任何字符一样加密像657这样的整数字符串，但这不包括'+'和'/'和'\'

解决方案

由于您使用的是ASP.NET， MachineKey 类 [ ^ ]可能是最简单的选项。

 私人 静态  readonly   string  [] QueryStringPurposes = {  ProtectQueryString}; 
 
  public   static   string  EncryptQueryString（ string  plainText）
 {
  byte  [] userData = Encoding.UTF8.GetBytes（明文）; 
  byte  [] encryptedData = MachineKey.Protect（userData，QueryStringPurposes）; 
  string  encodedData = Convert.ToBase64String（encryptedData）; 
  return  HttpUtility.UrlEncode（encodedData）; 
} 
 
  public   static   string  DecryptQueryString（ string  cipherText）
 {
  string  decodingData = HttpUtility.UrlDecode（cipherText）; 
  byte  [] userData = Convert.FromBase64String（decodingData）; 
  byte  [] decryptedData = MachineKey.Unprotect（userData，QueryStringPurposes）; 
  return  Encoding.UTF8.GetString（decryptedData）; 
} 

使用MachineKey API保护ASP.NET中的值brockallen [ ^ ]

您可以使用标准加密例程（例如，参见 System.Security.Cryptography命名空间 [ ^ ]）然后使用获得的字节的十六进制表示

Hi ,

is there any way i can encrypt the integer string like "657" to any character but this will not include '+' and '/' and '\'

解决方案

Since you're using ASP.NET, the MachineKey Class[^] is probably the simplest option.

private static readonly string[] QueryStringPurposes = { "ProtectQueryString" };

public static string EncryptQueryString(string plainText)
{
    byte[] userData = Encoding.UTF8.GetBytes(plainText);
    byte[] encryptedData = MachineKey.Protect(userData, QueryStringPurposes);
    string encodedData = Convert.ToBase64String(encryptedData);
    return HttpUtility.UrlEncode(encodedData);
}

public static string DecryptQueryString(string cipherText)
{
    string decodedData = HttpUtility.UrlDecode(cipherText);
    byte[] userData = Convert.FromBase64String(decodedData);
    byte[] decryptedData = MachineKey.Unprotect(userData, QueryStringPurposes);
    return Encoding.UTF8.GetString(decryptedData);
}

Use the MachineKey API to protect values in ASP.NET | brockallen[^]

You could use a standard encryption routine (see, for instance System.Security.Cryptography Namespace[^]) and then use the hexadecimal representation of the obtained bytes.
