C#實現MD5加密

C#實現MD5加密。

1、創建MD5Str.cs加密處理類

?

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、運行測試

?

static?void?Main(string[]?args)??
{??
????string?data?=?"123456789";??//要加密的數據????
????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();????
}??
