View 3 RepliesVS 2008 AVRdude Encrypt/decryption HEX File On The Fly In VB?
Oct 8, 2010i am looking to decrypt my HEX code file for an ATTiny chip and programming it using the AVRDude command line interface. Problem being, i do not want the user to be able to see what the HEX file is at any given time. VB.net Cryptography crypt the HEX file before i put it onto the server and then decrypt it after the program downloads it from the server and runs it through the program without seeing the decrypted HEX file?
Obviously the HEX file can not stay encrypted while being programmed to the ATTiny chip so how can i go about it so that i can create the original HEX file to be programmed within the program without having to worry about it writing a temporary file to the hard drive and then deleting it afterwards? (Because they could close the program after it does that temp file and they would be able to navigate and open it and see the code)

View 4 RepliesVS 2008 Save File And Encrypt Or Have Unique Save Name?
Mar 19, 2009My question is simple (the answer may not be...), What I am looking for is a way to save a file as an encrypted file (so know one can open it except in visual basic or a way to save it with a unique ending that only visual basic will recognize. I will also need to know of a way to open or load the file to.
This is going to be used in a game I am working on (and yes...I know visual basic isn't really meant for games, but it is coming together pretty well). I was originally going to have it save as a text file, but then everyone could open, read it and even change there stats. That is what this file will contain, the stats for their character, and when they load it, it will place the values into the correct spot.
I am a partial beginner or intermediate coder, I can understand code, I just don't know all there is, like saving and loading, and this is probably a little harder.

Dec 23, 2011I ended up getting this properly working, as far as encrypting a file goes:How to encrypt and decrypt a file by using Visual Basic .NET or Visual Basic 2005 However, the catch is I have to change the name of the output file. What I was hoping to do is overwrite the original with the encrypted file, but when I tried that on a large file, it ended up only getting about 8 bytes of it.
Does anybody have any suggestions or recommendations? The overall idea is that I want to keep a file encrypted until it needs to be unencrypted for use by a program, but I'm not sure if there are better tools out there or if there's a better way of accomplishing this.
Question 2: I would really, really like to encrypt an entire folder, which I'm guessing would be faster than file by file, but when I try I keep getting access denied errors, even with DOS Cipher. Is there a way to do this with a key?
Encrypt Data And Put It On A Txt File?
Apr 23, 2009I made a program that encrypts data and puts it on a txt file. There are two parts of information that need to be "linked" to the other. Say its Person 1, then Person 1 gender, they need to be placed together. Each encrypted piece of seperated by a ";". I have it read the file and place the information on a Rich Text Box. How can I read all the encrypted info and stop at ";" then place that into a variable then read the next bit? I did this a while back but I used StreamReader/StreamWrite and can't remember how I did it. Right now it reads through the open file dialog and writes it to the Text Box with this command writetext.LoadFile(sFilePath, RichTextBoxStreamType.PlainText)

Feb 4, 2011I have a page that has a few text boxes on it and are filled based upon a persons information. Like Name, telephone number, address etc
The data is stored in an Access DB.
I want to add a check box and have a label beside it that if it's checked it shows a hyperlink to a pdf file, if its not checked the link disappears, so toggle between the two.
Here's the check box I have so far, which isn't much:

I need this hyperlink/ string to be encrypted based upon the persons name, so each person has its own pdf file and no one can just guess anothers pdf file and have access to it....
The pdf file will be stored in a virtual directory within the site.

Allowing VB To Encrypt A Txt File And Read It?
Jan 13, 2009I have been successful in making an anti-hack program that uses a list from the local computer, this is at the moment a text file that can easily be modified, so my question is.Is there a way to replace this .txt file with a more secure format, one that cannot be decrypted (or is very hard to decrypt) without changing all my code?
the only thing i have to use the txt file for is adding the contained items to a listbox. Also, it would be possible for be to use SQL as i am using a dedicated server for the automatic update, so can use it as a remote library for the app the connect to.

By the way, it is ok to convert the text to a byte array using the system.text.encoding.ascii.getbytes() right? The reason i want to encrypt/compress only a part of a file is because i don't want to encrypt or compress the file header. That way the program can gather info about whether the file is compressed or encrypted.
