This article mainly introduces the MD5 encryption function and usage implemented in C#, and analyzes the definition and usage of the C# MD5 encryption class in the form of examples. Friends in need can refer to it. Next
The example in this article describes the MD5 encryption function and usage implemented in C#. Share it with everyone for your reference, the details are as follows:
1. Create MD5Str.cs encryption processing class
public class MD5Str { /// <summary> /// 字符串MD5加密 /// </summary> /// <param name="Text">要加密的字符串</param> /// <returns>密文</returns> public static string MD5(string Text) { byte[] buffer = System.Text.Encoding.Default.GetBytes(Text); try { System.Security.Cryptography.MD5CryptoServiceProvider check; check = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte[] somme = check.ComputeHash(buffer); string ret = ""; foreach (byte a in somme) { if (a < 16) ret += "0" + a.ToString("X"); else ret += a.ToString("X"); } return ret.ToLower(); } catch { throw; } } }
2. Run the test
static void Main(string[] args) { string data = "123456789"; //要加密的数据 string encodeStr = ""; //加密后文本 encodeStr = MD5Str.MD5(data); Console.WriteLine("原文本:{0}", data); Console.WriteLine("加密后文本:{0}", encodeStr); Console.Read(); }
