View 1 RepliesI've been receiving pdf files that I have been processing with the PDFsharp libraries. These files where 128-bit RC4 encrypted. Now I getting files that are 128-bit AES encyption.
I'm getting this exception "The PDF document is protected with an encryption not supported by PDFsharp."
Is AES just not supported, or do I need to change the method in which I open the file? [code]...
I have to make files encrypt in my application. Now, I'm writing the encrypted data to temporary files (fsOutput in the code). I upload this file by FTP to the server. How should I rewrite my code if I want to upload without creating a temporary file and by using stream? My FTP client is able to upload from stream. My FTP client uses PutFile method to upload files ('Upload from stream by StarkSoft ftp.net in my code)

I am attempting to find some code to use in VB.NET to decrypt a string that has been encrypted using the Java crypto libary.All of the code I have found so far uses an Initialisation Vector and Key to decrypt but the string has been encrypted using the Key only. (Using an Initialisation Vector is apperently an optional step in Java).Does anyone know of code that I can use (preferably in VB.NET but i could convert C#) to decrypt AES 128 Bit encoded string without an Initialisation Vector?

View 7 RepliesI've mad a program that produces barcodes using crystal reports and I'm having trouble trying to get the dll file for the barcode to be moved into the folder where crystal reports looks for this.I'm using a development project to create an installer for the program in vb 2010.i have tried just copying the dll file during the program start up if its not in the correct location but get the error saying that i dont have a high enough permission level to do this, would registering the dll file work seeing as its a 3rd party file and crystal reports expects it in a specific location?
View 4 RepliesI have written a simple app that allows our clients to access documents they might need throughout their time of doing business with us. They access these document via a button click event. First off I'd like to publish this program and install it onto a CD so that the end user does not have to install anything on their machine. They just simply pop the CD in and the program runs and they can click on whatever document they need. I'm having to trouble figuring out how to install it on a CD. I am also pretty sure i've done my mouse click events incorrectly because i have the exact path to the documents in my resources file.
i'm currently using the "System.dianogistics...process"(i'm not sure if thats the exact syntax and i forgot a couple of the words) function(i'm not sure if this is a function or not. i'm not super familar with VB). but when i use this method it requires the exact path for the file. which doesn't make sense if i want it on a CD which would change the location of the file for my C: to E:.
I could not figure out the key to installing folders/subfolders/.rtf files during deployment/installation. The key here is to 'add' folders and subfolders to the project in solution explorer, then adding existing item (.text (.rtf files in my case) files) then selecting the .rtf file in solution explorer.go to its properties and under 'Build Action' select 'Content' (very Important!). Then under 'Copy to Output' select 'Copy if newer'!Then in code to access these files you use the following code:
Me.RichTextBoxDisplay.LoadFile(Path.Combine(Application.StartupPath, "KJV BibleOTExodusExodus KJV.rtf"))
Finally after 3 days of research and 2 days at the msdn forum picking peoples minds (smarter than mine) and lots of prayer, I got it!
I created a program and published it using the wizard through the "Property" in menu.
When I used the Published program to Install it in my same computer it got installed in "StartMenu".
I didn't get the option to select the Drive for Installing it like what we get when installing other program.
how to make that option to appear on installing the program?

View 2 RepliesI would like to know how I could encrypt the url and store the encrypted value in the dll?
And I would also like to decrypt it from the dll when I need it for later?
i am trying to decrypt a file that was encrypted with Des. However not all of the file is encrypted just a few lines are. Here is an example of the file im trying to decrypt:
Random text
Encrypted Text
MD5 Hash
Encryption Key(Only there for tests)
Number of encrypted lines
The idea is to read the last three lines into variables and use them to decrypt the text. At the moment i use the number of lines - (the number of encrypted lines + 3) to find where the encrypted text starts. Then i was trying to copy the encrypted text to a temp file so i could run the code bellow on it, however i am getting an encoding error apparently i need to be using base64 or something. So my question is can anybody explain to me or show me how i can pull the encrypted text out of the file so that i can use the code bellow on it.
Dim DES As New DESCryptoServiceProvider()
'A 64-bit key and an IV are required for this provider.
'Set the secret key for the DES algorithm.
