Node Encrypt

ComfyUI-NodeEncrypt

Encrypt sensitive node parameters in ComfyUI workflows. Widget values are encrypted in-browser and stored in the workflow JSON — the password never leaves your machine.

Features

• Per-node encryption: Right-click any node → Encrypt Node. Its widgets are replaced by a lock overlay.
• Group encryption: Right-click a group → Encrypt Group. All nodes inside the group are encrypted at once.
• Multi-select encryption: Select multiple nodes, right-click the canvas → Encrypt Selected.
• Decrypt on demand: Right-click an encrypted node → Decrypt Node. Enter the same password to restore values.
• Survives save/load: Encrypted workflows can be saved, shared, and loaded. Only someone with the password can decrypt.

How it works

| Step | Detail | |------|--------| | Encryption | PBKDF2 (100 000 iterations) + AES-256-GCM via browser Web Crypto API | | Storage | __ENCRYPTED__:<base64(salt+iv+ciphertext)> in widgets_values[0] | | Security | Password is never sent to the server or stored anywhere |

Installation

1. Clone into ComfyUI/custom_nodes/:

   cd ComfyUI/custom_nodes/
   git clone https://github.com/your-name/ComfyUI-NodeEncrypt
   

2. Restart ComfyUI (or refresh the browser page).
3. Right-click any node → Encrypt Node.

The plugin is also available through ComfyUI Manager.

Usage

Encrypt a single node

Right-click the node → 🔒 Encrypt Node → enter + confirm a password.

The node becomes locked with a dark overlay. To decrypt, right-click the overlay → 🔓 Decrypt Node → enter the password.

Encrypt a group

Right-click the group border → 🔒 Encrypt Group → enter a password. All nodes whose bounding box is fully inside the group are encrypted.

Encrypt multiple selected nodes

Select nodes (Ctrl+click / drag-select), right-click canvas → 🔒 Encrypt Selected.

Decrypt

Right-click any locked node → 🔓 Decrypt Node. If the password is wrong, the values stay encrypted.

Technical notes

• The original node title is saved alongside encrypted values so it can be restored on decryption.
• After decryption, values are re-populated in the node widgets and the overlay is removed.
• Encrypted nodes export with full encryption metadata in the workflow JSON — no plaintext values leak.
• Overlay uses a position: fixed DOM element that covers the node (including the title bar) at z-index: 99999.
