easygen

Easygen is a lightweight, easy-to-integrate library that allows you to generate and validate software licenses in Python using digital signatures. Protect your applications from unauthorized use by linking licenses to the user's machine via HWID, all without relying on external servers.

Features

• Digital signature with private key (RSA)
• Local validation without internet
• Licenses linked to the HWID machine
• Expiration date validation

Usage/Examples

License validation

from easygen.license_validator import validate_license

if validate_license("license.lic", "public_key.pem"):
    print("Valid license")

License generation

from easygen.license_generator import generate_license

generate_license(
    user="pc-i5-2024",
    hwid="EXAMPLE_12345_6789",
    expiry_date_str="2025-12-31",
    private_key_path="private_key.pem",
    output_path="license.lic"
)

Installation

Before using, you need to generate the private and public keys

# Private key (DO NOT SHARE)
openssl genrsa -out private_key.pem 2048

# Public key (This one must be included with the software)
openssl rsa -in private_key.pem -pubout -out public_key.pem
