cipher_wire

cipher_wire is a Python module that provides implementations of classical encryption methods like the Caesar cipher, Playfair cipher, Transposition Matrix, and Vigenère cipher. The module includes a Command-Line Interface (CLI) for ease of use and also offers a Graphical User Interface (GUI) for users who prefer a visual experience.

Usage

Command-Line Interface (CLI)

The cipher_wire CLI allows you to encrypt and decrypt text using classical encryption methods. Run the following command for usage information:

cipher_wire -h

CLI Syntax

cipher_wire [-h] [-o OUTPUT] [-f FILE] [-k KEY] [--method {ceaser_cipher,playfiar,transpositionmatrix,vaigenere}] [--gui] [input]

Arguments:

• input: The text to be encrypted or decrypted (optional if -f is used).
• -h, --help: Show help message and exit.
• -o OUTPUT, --output OUTPUT: File to write the output (encrypted/decrypted text).
• -f FILE, --file FILE: File containing the input text.
• -k KEY, --key KEY: Key to be used for encryption or decryption.
• --method {caesar_cipher,playfair,transpositionmatrix,vaigenere}: Specify the encryption method.
• --gui: Launch the GUI interface.

Examples:

Encrypt text using Caesar cipher:

cipher_wire --method caesar_cipher -k 3 "HELLO WORLD"

Decrypt a file using Playfair cipher:

cipher_wire --method playfair -k "SECRET" -f encrypted.txt -o decrypted.txt

Encrypt text using Vigenère cipher:

cipher_wire --method vaigenere -k "KEY" "HELLO WORLD"

Encrypt using Transposition Matrix:

cipher_wire --method transpositionmatrix -k 4 "HELLO WORLD"

Launch the GUI interface:

cipher_wire --gui

---

GUI Interface

The GUI provides a simple and intuitive interface for encryption and decryption. Launch the GUI by running:

cipher_wire --gui

From the GUI, you can:

• Choose the encryption method.
• Enter the input text or load a file.
• Specify the key for encryption or decryption.
• Save the results to a file.

Encryption Methods

Caesar Cipher

A substitution cipher that shifts the characters in the plaintext by a fixed number (key).

Playfair Cipher

A digraph substitution cipher that uses a 5x5 grid of letters constructed from the key.

Transposition Matrix

A cipher that rearranges the characters in the plaintext according to a specific matrix or grid pattern based on the key.

Vigenère Cipher

A polyalphabetic cipher that uses a keyword to shift the letters in the plaintext. The shifts are based on the corresponding letters of the keyword.
