inferlock 0.4.0

File encryption and licensing for AI models

inferlock

Protect AI model files with encryption and license-based runtime loading.

inferlock encrypts model files and loads them securely with expiration-based licenses.

---

Features

• Model file encryption
• Runtime in-memory decryption
• License-based loading
• Expiration-based license
• Single-command packaging
• Bundle-based distribution
• CLI-first design

---

Installation

pip install inferlock

or local dev:

pip install -e .

---

Quick Start

Encrypt model and create license:

inferlock encrypt model.pt --expire 30d

Output:

model.inferlock/
 ├── model.inferlock
 └── license.inferlock

Load model:

from inferlock import load

model = load("model.inferlock")

---

CLI Usage

Encrypt model:

inferlock encrypt model.pt --expire 30d

Generate license manually:

inferlock license model.key --expire 30d

Show bundle info:

inferlock info model.inferlock

---

Device Binding

Bind license to machine:

inferlock encrypt model.pt --expire 30d --bind-device

The license will be tied to the current machine's MAC address and cannot be used on other devices.

Bundle Structure

model.inferlock/
 ├── model.inferlock
 └── license.inferlock

Load bundle:

from inferlock import load
