cryptography TransformFinalBlock 返回指定长度的哈希值

 1 MD5 md5 = MD5.Create();
 2             var by = md5.ComputeHash(Encoding.Unicode.GetBytes("123456"));
 3             StringBuilder sb = new StringBuilder();
 4             foreach (var item in by)
 5             {
 6                 sb.Append(item.ToString("x"));
 7             }
 8            
 9             Console.WriteLine(sb);
10             StringBuilder sbb = new StringBuilder();
11            var t = md5.TransformFinalBlock(by, 0, by.Length/2);
12            foreach (var item in t)
13            {
14                sbb.Append(item.ToString("x"));
15            }
16            Console.WriteLine(sbb);
17            
18             Console.ReadLine();

1，返回指定长度的哈希值

 

 

2.代码：

 

 1 MD5 md5 = MD5.Create();
 2             var by = md5.ComputeHash(Encoding.Unicode.GetBytes("123456"));
 3             StringBuilder sb = new StringBuilder();
 4             foreach (var item in by)
 5             {
 6                 sb.Append(item.ToString("x"));
 7             }
 8            
 9             Console.WriteLine(sb);
10             StringBuilder sbb = new StringBuilder();
11            var t = md5.TransformFinalBlock(by, 0, by.Length/2);
12            foreach (var item in t)
13            {
14                sbb.Append(item.ToString("x"));
15            }
16            Console.WriteLine(sbb);
17            
18             Console.ReadLine();
