Need to design a program that can encrypt and decrypt messages stored in simple text files using a private key stored in a separate file. Software should also be able to allow the users to enter simple messages that either displays the encrypted or decrypted message. The encryption method should use a simple substitution method. It should be set out in the following format:
Example (the "@" is the separator):
@
The character The Code End of line
A @ 4gh EOL
B @ 84!9 EOL
Has to use the 256 ASCII character codes. The separator will be used to separate the character and its corresponding code.Here are the pseudocodes I have come up with:
� Read any private key file
separator = readline(file);
while not EOF(file) do
tempStr = readline(file);

View 2 RepliesI want to make a program to encrypt and decrypt messages using a word cipher or random lettering(no duplicate letters) etc.
I've got 2 input boxes:
input text and keyword box
Two Buttons:
encrypt and decrypt
This is about all I have coded so far
Code:
Private Sub Encrypt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Encrypt.Click
Dim EncryptInput As String
[Code]....
I have a few guess how to do this (not 100%) but setting up some sort of array might be one (not sure if it's the easiest)
Edit: one thing for sure I want to be able to separate the characters in the keyword into the start of an array (if the array is the best option)
I don't necessarily need code, I just need some advisement on how to approach this with commands. I don't know too many commands (only remember some fortran)

View 1 RepliesI am interested in knowing if non-text files like .xls/.xlsx or .doc files can be encrypted... From the Devlopers Guide on MSDN, I found code snippets that allow encryption / decryption of .txt files. This works absolutely fine.

View 4 RepliesI save data from datagridview to text file . I also load the same data from text file into datagridview for edit and update the same thing to text file. Now i want to make my Drill layer header.txt in encrypted format to prevent anyone to open that file and modify out of program. They only can modify it through the program How can we do like this?
My Drill Layer Header.txt file is like this
T240C3.175F012S27H2000
T239C0.95F034S55H1000
T236C1.2F029S48H2000

This code can encryp the text file. But accrding to this code EncryptFile("c:\Drill Layer Header.txt", _ "c:\Drill Layer Header original1.txt", _ sSecretKey) It ask for input and output file. So it take data from Drill Layer Header then encrypt the save in drill layer header original.txt. I want it to take data from drill layer header and encrypt and save in same file.
