ComfyUI Encryption Scripts - Cross-Platform Decryption
|
||||
Works with both DropSend and DriveSend nodes
|
||||
Compatible with macOS, Windows, and Linux
|
||||
|
||||
============================================================
|
||||
LOCAL USE ONLY - Run this on your local machine to decrypt
|
||||
.enc files downloaded/synced from Dropbox or Google Drive.
|
||||
Do not run on cloud instances (RunPod, etc.)
|
||||
============================================================
|
||||
|
||||
Key retrieval methods (checked in order):
|
||||
- COMFYUI_ENCRYPTION_KEY environment variable
|
||||
- comfyui_encryption_key environment variable
|
||||
- DROPSEND_ENCRYPTION_KEY environment variable
|
||||
- DRIVESEND_ENCRYPTION_KEY environment variable
|
||||
- macOS Keychain (ComfyUI_Encryption_Key, DropSend_Encryption_Key, or DriveSend_Encryption_Key)
|
||||
- Linux Secret Service (ComfyUI, DropSend, or DriveSend)
|
||||
- Manual input
