本文实例分享了使用.NET Core实现MD5加密解密字符串的具体代码，供大家参考。

csharpusing System;using System.Security.Cryptography;using System.Text;

public class MD5Encryptor{ public static string Encrypt(string text, string sKey) { using (MD5 md5=MD5.Create()) { byte[] inputBytes=Encoding.ASCII.GetBytes(text + sKey); byte[] hashBytes=md5.ComputeHash(inputBytes);

StringBuilder sb=new StringBuilder(); for (int i=0; i

public static string Decrypt(string text, string sKey) { using (MD5 md5=MD5.Create()) { byte[] inputBytes=Encoding.ASCII.GetBytes(text + sKey); byte[] hashBytes=md5.ComputeHash(inputBytes);

StringBuilder sb=new StringBuilder(); for (int i=0; i

本文实例为大家分享了.net core使用MD5加密解密字符串的具体代码，供大家参考，具体内容如下

/// <summary> /// 加密 /// </summary> /// <param name="Text">要加密的文本</param> /// <param name="sKey">秘钥</param> /// <returns></returns> public static string Encrypt(string Text, string sKey="test") { DESCryptoServiceProvider des = new DESCryptoServiceProvider(); byte[] inputByteArray; inputByteArray = Encoding.Default.GetBytes(Text); des.Key = ASCIIEncoding.ASCII.GetBytes(Md5Hash(sKey).Substring(0,8)); des.IV = ASCIIEncoding.ASCII.GetBytes(Md5Hash(sKey).Substring(0, 8)); System.IO.MemoryStream ms = new System.IO.MemoryStream(); CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(), CryptoStreamMode.Write); cs.Write(inputByteArray, 0, inputByteArray.Length); cs.FlushFinalBlock(); StringBuilder ret = new StringBuilder(); foreach (byte b in ms.ToArray()) { ret.AppendFormat("{0:X2}", b); } md4j= ret.ToString(); return ret.ToString(); }

/// <summary> /// 解密 /// </summary> /// <param name="Text"></param> /// <param name="sKey"></param> /// <returns></returns> public static string Decrypt(string Text, string sKey = "test") { DESCryptoServiceProvider des = new DESCryptoServiceProvider(); int len; len = Text.Length / 2; byte[] inputByteArray = new byte[len]; int x, i; for (x = 0; x < len; x++) { i = Convert.ToInt32(Text.Substring(x * 2, 2), 16); inputByteArray[x] = (byte)i; } des.Key = ASCIIEncoding.ASCII.GetBytes(Md5Hash(sKey).Substring(0, 8)); des.IV = ASCIIEncoding.ASCII.GetBytes(Md5Hash(sKey).Substring(0, 8)); System.IO.MemoryStream ms = new System.IO.MemoryStream(); CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(), CryptoStreamMode.Write); cs.Write(inputByteArray, 0, inputByteArray.Length); cs.FlushFinalBlock(); return Encoding.Default.GetString(ms.ToArray()); }

/// <summary> /// 32位MD5加密 /// </summary> /// <param name="input"></param> /// <returns></returns> private static string Md5Hash(string input) { MD5CryptoServiceProvider md5Hasher = new MD5CryptoServiceProvider(); byte[] data = md5Hasher.ComputeHash(Encoding.Default.GetBytes(input)); StringBuilder sBuilder = new StringBuilder(); for (int i = 0; i < data.Length; i++) { sBuilder.Append(data[i].ToString("x2")); } return sBuilder.ToString(); }

调用加密 解密看效果

public static string md4j = ""; static void Main(string[] args) { //加密 Encrypt("123456"); Decrypt(md4j); }
