We want to give the calling website 'test' string that links back to the guid of our table which tells the Silverlight application what it's task is when they arrive. We also use this guid for authentication on our application among other things.
I have a URL www.site-address/site-page/page1.aspx?username=deepu&password=deepu how can i change the URL to www.site-address/site-page/page1.aspx?username=232322323232&password=2323232322323 ie i want to encrypt the fields i pass through the URL to encrypt and decrypt the URL in C# using .net,now i am using response.redirect and pass these values as query string...
A folder on File System contains .xml files, .txt files and a file exposed by third party tool. Using c# (in VS 2008), I want to encrypt the whole folder in someway before transferring it through FTP.
I have followed the method in this article, but it has the drawback that is uses reflection on an internal method. This has caused it to be flagged in a code review -- it is not future-proof as the internal implementation may change.
Is there a method with identical functionality which doesn't require using encryption on internal methods?
I am using .NET Framework 3.5 SP1 (Assume I cannot change framework versions)
I'm very new to asp and vb.net, I've just learned about regular expression validation but one thing is bugging me: How can I hide my expression from being viewed on my source code?
The plan is to make a very simple 'login' type of page. I know this goes against all that is holy in this kind of operations, but it's just something I'd like to try out.
Also, after the expression has been validated, I want to load another page, I was thinking of achieving this with:
i am sending pdf attachment mail through the vb.net program .it will go and save in the mail. i want to encrypt and send this pdf. if user open that pdf document trough the it should ask username/password and allow it save local system how to achieve this.
I have a website which has reference to a service layer through which it calls the procedures.I have a web.config file in my service layer.I want to know is that possible to encrypt the database password alone in connection string.if so how it could be done using Enterprise library 5.0.And whether encrypted password should be decrypted before procedure call or it would automatically take decypted value for procedure call.
I am looking into the possibility of shortening / encrypting a url which will be from 150 to 250 characters in length to maximum 12 characters using an algorithm. Initially I am doubting it's possible but I wanted to leverage the great minds of StackOverflow :)
the algorithm should be one that can be written in classic asp, sql, c#, vb, or foxpro or other language.
Is that even possible without a database centric approach?
I was reading here that AES in CFB mode, will do a stream cipher and the output length will be the same as the input length. Is there any way to shorten it even more?
I was wondering how you could encrypt/decrypt your querystring in a simple asp.net page? some values need to be passed between different pages but the querystring cannot be changed or read.
Some say httphandles could be the solution for this.
MORE BACKGROUND INFO:
this is the problem, sometimes the sessions disappear without any reason (well there must be one but I don't know it yet). I've looked into the possible reasons but nothing that could cause it is happening. Therefore I cannot rely on it anymore. The cookie solution is a possibility but it will be more work to implement than simply using the querystring. The url can be copied at any time just not changed!
I am having an algorithm for validating my license file, i need to encrypt the license file validation code in my project, So that even the hacker decompile the dll, he could not decrypt the license validating code, is it possible?
We can precompile our (ASP.NET) websites and can publish only the IL code, so that the source code is not available to the customer.
But how do we do it for stored procedures written in SQL Server. I mean, when we give the customer the DB, he could see all my stored procedures and can modify the same..
I have table of users with their passwords. Can I just manually encrypt the passwords now till the app is fixes that would make the encrytion process in this program? and if yes how do I do this?
