这个C#类封装了一些hash加密的成果，，可以用于得到随机哈希加密字符串使用非常便利
using System; using System.Text; using System.Security.Cryptography; namespace DotNet.Utilities { /// <summary> /// 得到随机安适码（哈希加密）。 /// </summary> public class HashEncode { public HashEncode() { // // TODO: 在此处添加结构函数逻辑 // } /// <summary> /// 得到随机哈希加密字符串 /// </summary> /// <returns></returns> public static string GetSecurity() { string Security = HashEncoding(GetRandomValue()); return Security; } /// <summary> /// 得到一个随机数值 /// </summary> /// <returns></returns> public static string GetRandomValue() { Random Seed = new Random(); string RandomVaule = Seed.Next(1, int.MaxValue).ToString(); return RandomVaule; } /// <summary> /// 哈希加密一个字符串，sharejs.com /// </summary> /// <param></param> /// <returns></returns> public static string HashEncoding(string Security) { byte[] Value; UnicodeEncoding Code = new UnicodeEncoding(); byte[] Message = Code.GetBytes(Security); SHA512Managed Arithmetic = new SHA512Managed(); Value = Arithmetic.ComputeHash(Message); Security = ""; foreach(byte o in Value) { Security += (int) o + "O"; } return Security; } } }
