Secrets Manager

This project is a simple application built using Python and Tkinter for encrypting and decrypting secret messages. The application allows users to save their secrets securely with encryption and decrypt them when needed.

Features

• Encrypt secret messages with a master key.
• Save encrypted messages to a file.
• Decrypt messages using the master key.
• Simple and user-friendly GUI.

Getting Started

Prerequisites

Ensure you have Python installed on your machine. This project was developed with Python 3.8.

Installation

1. Clone the repository:

   git clone https://github.com/YusufCelebii/SecretNotes
   cd secrets-manager

2. Install required packages (Tkinter is usually included with Python):

   pip install tkinter

Running the Application

1. Navigate to the project directory.
2. Run the main.py file:

   python main.py

Usage

1. Enter your title: Provide a title for your secret.
2. Enter your secrets: Type your secret message.
3. Enter your master key: Provide a master key for encryption.
4. Encrypt & Save: Click this button to encrypt and save your message.
5. Decrypt: To decrypt a message, paste the encrypted text into the text area, provide the master key, and click this button.

GUI Overview

The GUI consists of the following components:

• Title Entry (title1): A text entry field where you enter the title for your secret.
• Secrets Textbox (text1): A text box where you enter the secret message that you want to encrypt or decrypt.
• Master Key Entry (master_key): A text entry field where you enter the master key used for encryption and decryption.
• Encrypt & Save Button (save_button): A button that, when clicked, encrypts the entered secret using the master key and saves it to the file My Secrets.txt.
• Decrypt Button (decrypte_button): A button that, when clicked, decrypts the entered encrypted message using the master key and displays the decrypted message in the secrets textbox.

Files

• main.py: The main script containing the application code.
• My Secrets.txt: The file where encrypted secrets are stored.

Code Explanation

The application uses the Tkinter library to create a GUI and the base64 module for encoding and decoding the messages.

Encryption Function

def encode(key, clear):
    enc = []
    for i in range(len(clear)):
        key_c = key[i % len(key)]
        enc_c = chr((ord(clear[i]) + ord(key_c)) % 256)
        enc.append(enc_c)
    return base64.urlsafe_b64encode("".join(enc).encode()).decode()
