crypto-functions 2.0.0

A simple and secure Python module for hashing and encrypting data and files.

🔐 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
