Our website uses query strings to allow third party venders to retrieve information. The problem is other people are using these string to attack and steal information from our site. I need to secure these strings so that only people I allow to use the query string can use it. I do not want un authorized access being used with the query string. I would also like to show an encrypted version of this so that people cannot see how the string is used. I also need to hide the javascript that is calling these methods to prevent unauthorized people from figuring out what need to be sent to the query string.

Hello, As an experienced asp.net developer, i am very much interested to resolve the issue. To avoid the query string problem, normally form authentication is used in asp.net which might be implemented in your case also. Let's discuss more. Thanks

I have experience in working with .NET & Microsoft SQL Server. I think I can do this project for you. I have some question though: 1. How many query string do you have? 2. Your system allows query directly to the database? 3. By "people I allow", do you mean you will need another login system? 4. Why do you need to encrypt the query string? I mean why do you need to show it to people?

Hi, Following are my suggestion for your work: 1. All request to your site must be authorized (token authentication) 2. Query-string data must be encrypted 3. JavaScript files must be minified, so that it is hard to read. 4. Data passed in Ajax calls must be encrypted About me: My name is Tahir; I'm a Microsoft Certified Solutions Developer(MCSD) located in Islamabad. I've a sound experience in c#, asp.net, mvc, entity frame work, sql server, web api and json/xml. I'm highly interested in your work, and i believe it fits my area of expertise.

Hi, I have read your job description and understand the situation you are facing. possible solutions: 1. If you can ask your vendors to use post request , i can convert all your methods to POST so this problem will be gone from root. 2. If 1 solution cant possible , we can go with a Key saved in config and shared with all vendors , so they will send the key also with other params. and also we will encrypt the whole query string part of the url so if they know all old querystring values , they cant access what they want as they cant get the key(secure key) Hope you will like the solutions i provided. Thanks, Rohit

Hi there, how are you today? I read your project description and I'd like to help you out with it. I would recommend including an authentication key with the request and at the same time, encrypting it before sending it to the server. When the legal user intend to use the api, he/she will be asked of his/her own secret key, the secret key will then be used to create an authentication key (with some additional dynamic data alike date,ip.....) and all the request query will then be encrypted before being sent to the server.
