GlTF-Crypto

This package implements adaptive, hierarchical encryption and decryption of 3D .glTF or .glb files It is suppprted for Python3.10 and above.

Quickstart

Install:

pip install crypto-gltf

Loading a .gltf or .glb file:

from crypto_gltf import Asset

filepath = 'example/path/to/an/asset.glb'
asset = Asset.load(filepath)

Encrypting an asset:

encryption_response = asset.encrypt()

Exporting an encrypted asset:

save_directory = 'example/save/directory'
export_path = asset.save(save_directory)

Accessing encryption keys:

encryption_key = encryption_response.key
k1 = key.k1
k2 = key.k2
k3 = key.k3

Decrypting an asset:

Here k3 can be replaced by k1 or k2.

encrypted_asset = Asset,load(export_path)
encrypted_asset.decrypt(
    k3=encryption_response.key.k3,
)
encrypted_asset.save(save_directory)

Advanced Usage:

Encrypting images:

mesh_and_image_encryption_response = asset.encrypt(encrypt_images=True)

Configuring parameters:

configured_encryption_response = asset.encrypt(
    meshes_cipher_params=(1, 3, 10), #(p,q,r)
    images_cipher_params=(1, 1, 6), #(p,q,r)
    encrypt_images=True,
)
