c#实现md5加密示例

public static string  encryptwithmd5(string source)
    {
        byte [] sor=encoding.utf8.getbytes(source);
        md5 md5=md5.create();
        byte [] result= md5.computehash(sor);
        stringbuilder strbul=new stringbuilder(40);
        for(int i=0;i<result.length;i++)
        {
            strbul.append(result[i].tostring("x2"));//加密结果"x2"结果为32位,"x3"结果为48位,"x4"结果为64位

        }
        return strbul.tostring();
    }
