A?a?ydaki kodda önemli olan System.Web.Security synyfyny import etmemiz.E?er import etmezseniz “FormsAuthentication.HashPasswordForStoringInConfigFile “ de?eri hata verecektir.?ifreleme butonuna vermi? oldu?umuz olayda ise ilk textbox de?erini “FormsAuthentication.HashPasswordForStoringInConfigFile” olayyny kullanarak ?ifrelememiz.” FormsAuthentication.HashPasswordForStoringInConfigFile(sifrelenecek.text, “SHA1”)” olayynda SHA1 .net framework tarafyndan desteklenen bir algoritma. SHA1 yerine MD5 yazarsanyz de?i?ik bir algoritmayla ?ifrelemi? olursunuz.Yyi Çaly?malar
