Make An Encryption Program?
May 12, 2010My idea is to have an input and an output text box. When the user presses a button the program will encode what is in the input text box and output it into the output text box.I also want to encrypt it with a secret key where the user enters a letter or set of letters into a separate text box which will effect the output. This process can be reversed to decrypt

May 15, 2010I'm trying to do an encryption program that encrypts with AES256. I have searched for source codes, but I could not find proper result. Most of programs use Rijndael as algorithm, but I don't want using this class. I searched MSDN for AES classes, and I found AESCryptoServiceProvider, but I don't know how to use it.

Secure Program Data Encryption?
Sep 25, 2011What would be the best way of storing data securely away from users. What I have is a stack of files that get downloaded by the program, at the moment they COME encrypted, and stored in a temp location. Now where would be the be place to store them, and how would I store them? The program reads normal unencrypted files but in order for me to open them at the moment I nee to decrypt them in the temp folder and open them from there.This is bad because anyone could find the temp folder and simply copy out all the unencrypted files.Opening the files and then decrypting the bytearray is out of the question because the program only takes a filename as a option.

Mar 6, 2009I am currently working on a simple data encryption program in VB 2008 express. Basically, I want the user to be able to select any file type and the program will read the data and store it in a text box. The user would then input a key, push the encrypt button and the program would XOR each byte of data with each character from the key and store the data in the third text box. I have written a program that has similar functionality only, it will not read from files, it simply reads data from a text box, so I have a encryption algorithm that works.Here is my

Encryption / Decryption Program - Slow Process
Jul 18, 2010I was board making web browsers and OS so, I tried making an Encryption/Decryption program. I surfed the net and found a source code. But, after doing everything, I debug it, click the encrypt btn and nothing happens. I though the encrypting is a slow process. The thing is the process should be immediate cause I downloaded this web browser called 'Areo Pack'. It comes with a few other program and one of them in an Encryption/Decryption program. I tried it and it was done in a few seconds. I tried opening the encrypted file with notepad and I see a text file with Chinese, Japaneses, Korean, etc.

View 1 RepliesEncryption Of A Text File + Decryption For Security Program?
Feb 10, 2011What I've decided to start working on is pretty much a personal project but something I may use in my UNI course in due time. I'm creating a security program with a set of access codes (yes I am a bit of a star trek fan) - 4 in total to be exact. I want to be able to use an Encrypted key file in form of a simple notepad created text file to update the codes at any due time. All I'm looking to do is write the access codes to the text file (say for a friend to use the program), Encrypt the file through the program and be able to also decrypt to obtain the new access codes on demand also via the same program. Once decrypted the codes can be read and verified if the user has entered each one correctly. I could hard code the access codes into the program but would rather do it the way I've thought of.
Back in the days of the old VB6 there was a simple method but for some reason that doesnt work any more. What I guess I'm looking to do is have 4 text fields where 4 digit access codes are typed into, have the program take them and encrypt each one is then written to the text file. Hoping that will make it a bit clearer what I'm trying to achieve as I think I made it sound like I want to encrypt the text file after the info has been written to it, which is of course one option so wouldn't mind know how to do that too!

View 3 RepliesVS 2010 - File Saving - Simple Pseudo-encryption Program That Changes Each Character Into Another
Apr 22, 2011I recently made a simple pseudo-encryption program that changes each character into another. It is capable of encrypting and decrypting a string. This can also be done to any text file as well. The characters range from ASCII 32-254 (This on it's own may be an issue because of #127 being DEL).
Because I believed my own coding may be at fault, I attempted this with Triple Des with identical results.For Triple Des, the requirements for en/decryption was:
Encrypt: String to Byte
Decrypt: Byte to String
And to change them either direction, I used UTF8. I also attempted ASCII and UTF32, but I don't know what I should do. I am considering dropping this but I want to learn problems like this because I am currently in college and haven't started my core classes for programming yet and want the head start.
The point where I have come into a problem is attempting to do this to another file type like an image. I looked at the results from encrypting then decrypting and the results were similar, but it seems file encoding must be the culprit.
Generics - List(Of T) - Use It To Hold Items Of Several Types?
Oct 3, 2009Assuming a base type of "Message"...
[Code]...
I would like to have one collection of Message objects which can be either PhoneMessages or MailMessages, so that I can iterate through the list and deal with each message based on what type it happens to be.
Attempting just to use .Add() fails, saying that I can't add an item of type PhoneMessage to a List(Of Message). Is there some elegant way to accomplish what I'm trying to do? I had thought I could accomplish this with generics, but I think there's a gap in my understanding. If it can be accomplished in .NET 2.0, that would be ideal.

However, the list types are different. I want only to select based on column comparisons.

.net Encryption Result Does Not Match The Xcode Encryption Result Given The Same Input Parameters?

Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
May 27, 2012I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?
