Password-App

1. Overview The password manager is a program that helps save and retrieve passwords securely. It uses strong encryption to make sure no one can read stored passwords without the master password.
2. Key Features

• Save a master password securely using hashing.
• Encrypt and store passwords safely in a file.
• Retrieve passwords only after logging in with the master password.
• Generate strong, random passwords.

3. How to Run It Install GCC and OpenSSL. Compile the program with this command: gcc -o password_manager password_manager.c -lcrypto Run the program with this command: ./password_manager
4. What the Program Does - First, it asks for a master password and saves it securely.

• It lets you save passwords for different accounts (like email or social media).
• All passwords are encrypted and saved in a file.
• You can see your passwords only after logging in with the master password.
• It also generates random, strong passwords if you need them.

5. Why It Is Secure

• It uses AES-256, a very strong encryption standard.
• It uses PBKDF2 to make the master password harder to guess.
• Each password has unique encryption data.

6. Conclusion This password manager is a simple and effective tool for keeping passwords safe. Future versions could include backups or a better user interface to make it more useful.
