After the C # sha256 sha256 encryption and encryption js in C #, encryption is 44, two js or some online sites are 64-bit encryption, change how to choose the same encryption algorithm js and C # encryption result.

C # class library that comes with sha265 returns a byte [] array

The length of this array is 32, js is the sha265 64, each byte is to be directly converted into 2 hex string.

After encryption is C # 44 is due to the array would be base64 encoded string.

C # also directly converted into the corresponding byte to hex string and the js are the same.

Further, str converted into byte [] Encoding If different arrays, SHA different, are generally js utf8.

 

  public static string SHA256(string str)

         {

             //如果str有中文，不同Encoding的sha是不同的！！

             byte [] SHA256Data = Encoding.UTF8.GetBytes(str);

            

             SHA256Managed Sha256 =  new  SHA256Managed();

             byte []  by  = Sha256.ComputeHash(SHA256Data);

             

             return  BitConverter.ToString( by ).Replace( "-" ,  "" ).ToLower();  //64

             //return Convert.ToBase64String(by);                         //44

         }

 

         static  void  Main( string [] args)

         {

             string  s =  "hello world" ;    

//sha265=b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9

             string  sha = SHA256(s);

             Console.WriteLine( "{0}\n{1} \nLength: {2}" ,s, sha, sha.Length);

         }

I personally use! I do not know if you can add Q: 961823316
