Eclyptic is a lightweight Python library that implements a streamlined ECIES‑style encryption scheme utilizing:

• Elliptic‑Curve Diffie‑Hellman (ECDH) for key agreement
• HKDF‑SHA256 for symmetric key derivation
• AES‑GCM for authenticated encryption
• Compressed ECC public keys with compact Base64 URL-safe encoding (no padding)

Designed for ease of use, forward secrecy, and efficiency with arbitrary binary and text payloads.

Installation

# install from PyPI
pip3 install eclyptic

Quick Start

import eclyptic

# generate a compact base64-encoded keypair
priv, pub = eclyptic.keypair()

# encrypt data (bytes or UTF-8 string)
data = "secret data"
encrypted_data = eclyptic.encrypt(pub, data)

# decrypt back into raw bytes or UTF-8 text
decrypted_bytes = eclyptic.decrypt(priv, encrypted_data)
plaintext = decrypted_bytes.decode('utf-8')
