How should I store KEY from AES encrypt?
SceAES secaes = new SceAES("pomboSenha","G567EF33WQ19PL1S",12,45,256,"SHA1","systemSCE"); "pomboSenha" is the secretKey above.
Is safe to mantain it hardcoded in a class?
I have an asp.net page i do authentication and authorization of a user and user can make several ajax requests from this page. What i want to ensure is that the request only from this page so i will store some data(or token)(possibly a function of userID + user IP address + current time) encrypted in the page aswell as in the session so the requests that come with this token will only get served.

hey folks I got a general question that maybe some of you can just weigh in. I developed an online store for a client and people place orders online for a food ordering place however I am trying to find the best way to have the orders show up for them at the store. Currently I am sending an email and an autoprint software prints it out which works most of the time but not good enough sometimes it doesn't print. Anyone had similar issues or have other alternative solutions you may have heard off? Like I said the site sends an email to the customer and the store's email account.

View 9 RepliesIs it better to store images directly in a database or to just store the name of the file in the db and display that file? I would think that just storing the filename of the image would keep the db size low...
View 1 RepliesWeb service error response (code/message etc) would you store it in a database? or would you keep the error response in a method.By the time I'm done with this, there will be hundreds of error response, maybe in the future, thousands? (I dont know yet, depends how large this web service grows).EDIT: error response is the response returned back to the application via the web service, (not to be confused with error logging).
View 1 RepliesWe are creating a Silverlight application and need to have a few parameters pass in with the url from calling site.
example: http://oursite.com/index.aspx?test=d53ae99b-06a0-4ba7-81ed-4556adc532b2
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.
The guids are as such:
d53ae99b-06a0-4ba7-81ed-4556adc532b2
8354b838-99b3-4b4c-bb07-7cf68620072e
Encrypted, the values are much longer:

WVMN7B0FPa18/Q7+U4njb5AOKnx6Ga9xoAsvCET6MyjM5TV6dO86OexaCXDiXaES
My question is, with security in mind, should we give them the guid encrypted or like it is unencrypted?
What is everyone's experience with this type of parameter passing?

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'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:
<asp:TextBox ID="txtcp" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="CP Errada"
Display="Dynamic" ControlToValidate="txtcp" ValidationExpression="admin"></asp:RegularExpressionValidator>
and in vb:
If txtcp is validated then Response.Redirect("mypage.aspx") end if
But the syntax on this IF is obviously not right

View 1 RepliesI 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!
