在很多情況下，程序員都會將數(shù)據(jù)庫的連接字符串放在web中進行配置，它包含許多敏感信息，包括連接到數(shù)據(jù)庫的用戶名和密碼，那么asp.net 對中文漢字的加密與解密代碼大家了解多少呢？下面就跟著錯新技術(shù)頻道小編來了解吧！

復(fù)制代碼代碼如下:

protected void Page_Load(object sender, EventArgs e)
{
//加密算法
string username = "我是陳建勇";
//MD5加密 - 得到32位加密數(shù)據(jù),數(shù)據(jù)不好解密。過于復(fù)雜。
username =FormsAuthentication.HashPasswordForStoringInConfigFile(username, "MD5");
//SHA1加密 - 得到40位加密數(shù)據(jù),數(shù)據(jù)不好解密。過于復(fù)雜。
string username1 = FormsAuthentication.HashPasswordForStoringInConfigFile(username, "SHA1");
Response.Write(username+"
");
Response.Write(username1+"
");
//解密算法
//普通加密
string s = "我是陳建勇";
string encodestr = "";
byte[] bytes = System.Text.Encoding.GetEncoding(0).GetBytes(s);
try
{
encodestr = Convert.ToBase64String(bytes);
Response.Write("aa");
}
catch
{
encodestr = s;
Response.Write("bb");
}
Response.Write(encodestr+"
");
//普通解密
string decodestr = "";
byte[] bytes1 = Convert.FromBase64String(encodestr);
try
{
decodestr = System.Text.Encoding.GetEncoding(0).GetString(bytes1);
Response.Write("cc");
}
catch
{
Response.Write("dd");
decodestr = encodestr;
}
Response.Write(decodestr+"
");
//普通加密
string myname = "陳建勇";
myname = System.Web.HttpUtility.UrlEncode(myname, System.Text.Encoding.UTF8);
Response.Write(myname+"
");
//普通解密
myname = System.Web.HttpUtility.UrlDecode(myname, System.Text.Encoding.UTF8);
Response.Write(myname);
}
