Automatic1111 Extension

The Certivu extension for the Automatic1111 / Forge WebUI signs every image you save, with no change to your generation workflow. It hooks the WebUI’s image-save callback and wraps the certivu Python SDK.

Install

Download and extract the extension into your WebUI’s extensions folder:

cd stable-diffusion-webui/extensions
curl -L https://cdn.certivu.ai/integrations/a1111-latest.zip -o certivu.zip
unzip certivu.zip -d certivu && rm certivu.zip

Restart the WebUI. On the next launch the extension installs the certivu package automatically.

Configure

Open Settings → Certivu and set:

Setting	Description
Enable Certivu signing	Master on/off switch (off by default).
API key	Your ctv_key_… key.
Generator ID	A generator that supports the image format.
API base URL	https://api.certivu.ai, or the sandbox URL to avoid consuming quota.
Model name	Recorded with the signature; blank uses the active checkpoint name.
Overwrite saved file	On replaces the saved file with the signed one; off writes a sibling *-certivu.png.

Apply settings. From then on, saved images are signed automatically.

Notes

• Signing failures never interrupt generation — the extension logs a warning and keeps your original image.
• Each signed image counts against your plan quota. Use the sandbox while testing.
