Password Manager

My personal password management system implemented in C. This project allows users to securely store, retrieve, delete, and list passwords for services.

Features

• Add a Password: Securely store a password associated with a service.
• Retrieve a Password: View stored passwords after decryption.
• Delete a Password: Remove specific service-password entries.
• List Services: Display all stored services.
• Encryption: Uses a simple XOR-based encryption for educational purposes.

Requirements

• Compiler: GCC (or any C compiler)
• Operating System: Windows, Linux, or macOS

Compilation and Execution

Without Makefile

1. Navigate to the src directory:

   cd pass-manage

2. Compile the source files:

   gcc -o program main.c manage.c encryption.c -Wall -Wextra -std=c99

3. Run the executable:

   ./program

With Makefile
