create web api for exposing login to .Net Website from Android App

[anoop m]

Hello,

I have created a ASP.Net Web forms Website in which forms authentication is done

FormsAuthenticationTicket tkt;
string cookiestr;
HttpCookie ck;
tkt = new FormsAuthenticationTicket(1, txtuserid.Text, DateTime.Now,
DateTime.Now.AddMinutes(30), false, "your custom data");
cookiestr = FormsAuthentication.Encrypt(tkt);
ck = new HttpCookie(FormsAuthentication.FormsCookieName, cookiestr);
//if (chkPersistCookie.Checked)
// ck.Expires = tkt.Expiration;
ck.HttpOnly = true;
ck.Secure = true;
ck.Path = FormsAuthentication.FormsCookiePath;
Response.Cookies.Add(ck);

moreover - Salted MD5 is implemented for hashing the password with md5 and server side random number on ASPX and same process in ASPX.cs and checking the password for any tampering in server side. (every time a different hash of the password is transferred from client to server)

Now I want to create a web api that is to be used by Android App for authentication into the website. How can I do it, Is there a some other way.

Thanks
