C#生成MD 5代码示例

//Use input string to calculate MD5 hash

MD5 md5=System.S ec urity.Cryptography.MD5.Create();byte[] inputByt es=Sys tem.Text.Enc oding.AS CII.GetBytes (input);byte[]has hBytes=md5.ComputeHas h(input Bytes);

//Convert the byte array to hexadec imal string

StringBuilder sb=new StringBuilder();for(int i=0; i hashBytes.Length; i++)sb.Append(hashBytes[i].ToString(“X2”));

//To force the hex string to lower-case letters instead of

//upper-case,use he following line instead:

//sb.Append(hashBytes[i].ToString(“x2”));return s b.ToS tring();

}

用法string md5hash=CreateMD5 Hash(“abc defghijklmnopqrstuvwxyz”);

执行结果md5hash will contain this string:“C3FCD3D76192E4007DFB496CCA67E13 B”.C#里也可以直接使用S y st em.Web.S ec ur ity命名空间生成MD 5
