RSA encryption front-end JS encryption, back-end ASP.

Reference: http://www.ohdave.com/rsa/'s JS Encryption library

Front-end JS encryption code:

{            debugger;            var pwdstr = document.getElementById ("Txtpasswordstr"). Value;            var uidstr= $ ("#<%=txtuserstr.clientid%>"). Val ();            if (!pwdstr | | pwdstr.length = = 0 | |!uidstr | | uidstr.length==0) {                return false;            }            var keye = "<%=PubRsaKeyE%>";            var Keym = "<%=PubRsaKeyM%>";            Setmaxdigits (131);            var key = new Rsakeypair (Keye, "", Keym);            var pwdrtn = encryptedstring (key, pwdstr);            var uidrtn = encryptedstring (key, uidstr);            $ ("#<%=txtpassword.clientid%>"). Val (PWDRTN);            $ ("#<%=txtuser.clientid%>"). Val (UIDRTN);}

Background Decryption Code:

        Try        {            rsacryptoserviceprovider RSA = (RSACryptoServiceProvider) cache.get ("Privatekey");            Byte[] result = RSA. Decrypt (hexstringtobytes (password), false);            Password = Encoding.UTF8.GetString (result);            result = RSA. Decrypt (Hexstringtobytes (UserName), false);            UserName = Encoding.UTF8.GetString (result);        }        catch (Exception ex)        {            showmessage ("Authentication failed! "," The account or password you logged in is wrong! "," ");            return;        }    

A "parameter error" exception is reported in some development environments. However, the other project or server environment is normal.

No reason found, unknown principle Ah!!

Just make a record of it.
