🔐 Crypto Tools — Secure Hashing & Encryption for Python

A lightweight, beginner-friendly yet secure cryptography toolkit for Python. It supports password hashing, data hashing, and AES-GCM-based file encryption & decryption — all using modern, industry-standard cryptographic practices.

🚀 Features

✅ Password Hashing — Uses Argon2 (the most secure modern algorithm)
✅ Data Hashing — Fast and deterministic SHA-256 hashing
✅ File Encryption — AES-GCM authenticated encryption (confidentiality + integrity = security Pro Max)
✅ File Decryption — Securely decrypts files encrypted with the same password
✅ Key Derivation — PBKDF2-HMAC-SHA256 with 500,000 iterations
✅ Simple API — Four clean, easy-to-use functions

📦 Installation

1. Clone the repo:
git clone https://github.com/Anish-Sethi-12122/Crypto-Tools
cd Crypto-Tools

2. Install dependencies:
pip install -r requirements.txt

Or even better !!

Download it directly as a module and use it in your python projects.
pip install crypto-functions argon2-cffi cryptography

Caution- Always store your encryption passwords safely — losing them makes decryption impossible.

Security Pro Max:

AES-GCM for authenticated encryption
PBKDF2-HMAC-SHA256 with 500,000 iterations for key derivation
Argon2 for password hashing

🧪 Example Files

An example script is provided to demonstrate how to use each function.
