    Substitution Cipher Solver

    I am trying to make a substitution cipher solver in vb.net but whenever I try to solve a cipher text using methods other than shift it goes back to the original. This is the code I have so far
    Code:
    Dim Ctl As Control, nAsc As Int16
            For Each Ctl In Panel2.Controls
                If TypeOf (Ctl) Is TextBox Then
                    nAsc = Asc(Microsoft.VisualBasic.Left(Ctl.Name, 1))
                    If Reverse.Checked
    ...

  • how to make a vigenere cipher solver in vb.net?

    I am making a cipher solver in vb.net 2008 and I have made it solve ciphers for most ciphers but I can't make it do vigenere. I have got three textboxes named "EncryptionVige nere", "SolutionVigene re" and "Key" and a button called "SolveVigen ere"

    Note this is not a homework project

    Decrypting encrypted HTML

    I’ve been working on this for a while, but my rudimentary knowledge of JavaScript has prevented me from figuring this out. I have an HTML file that has been encrypted with JavaScript (at least it seems so). The page displays fine, but the source is unreadable.

    Thanks for any help.

    Code:
    <!DOCTYPE html    PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    Ceasar Cipher help

    Hi all, im writing a caesar cipher and ive done most of the program (see below)
    Code:
    def decrypt(ciphertext, shift):
        decrytped_text = " "
    
    
        for letter in ciphertext:
            if letter.isalpha():
                num = ord(letter)
                num += key
    
                if letter.isupper():
                    if num > ord('Z'):
                        num -= 26

    Help with a simple encryption program?

    Hello,

    I'm trying to make a simple Caesar cipher however instead of A-Z i want to also include 0-9. where 9 wraps back to A.

    The best i could can do shift letters and integers independently so a string like "TESTING SHIFT Z 9" with a key of 1
    becomes
    "UFTUJOH TIJGU A 0"

    9 wraps to 0 and Z wraps to A

    here is how I did that:

    Code:
        private
