CryptDeCrypt - Password Manager

Description

CryptDeCrypt is a secure password manager designed to encrypt and manage user passwords. The program utilizes encryption and hashing techniques to ensure the confidentiality and integrity of stored passwords.

Features

• Secure Password Storage: Passwords are encrypted using Fernet symmetric key encryption, and user-specific keys are stored in separate key files.

• User Authentication: Users are required to authenticate themselves with a master password before accessing the password manager.

• Password Strength Check: The program checks the strength of passwords against predefined criteria, ensuring they meet minimum requirements.

• SQLite Database: Passwords and user information are stored in an SQLite database, providing a structured and secure way to manage data.

• Password History: The program keeps track of password changes, maintaining a history of encrypted passwords associated with each user.

• GUI Interface: The graphical user interface (GUI) is built using Tkinter, providing a user-friendly experience for interacting with the password manager.

Modules Required

1. cryptography - Cryptography Library

   • Used for Fernet symmetric key encryption and hashing algorithms.

2. ttkthemes - Themed Tkinter Widgets

   • Provides additional themed styles for Tkinter widgets.

3. password_strength - Password Strength Library

   • Used for checking password strength against predefined criteria.

Requirements

• Python 3.x
• Install required modules: pip install -r requirements.txt

Getting Started

1. Clone the repository: git clone <repository-url>
2. Install required modules: pip install -r requirements.txt
3. Run the program: python main.py
4. Enter your master password to access the password manager.

Usage
