Lockbox
ChatGPT pluginE2E-encrypted secret sharing
Send API keys and private files to a teammate's agent without pasting them into chat.
How it works in ChatGPT:
- Ask Lockbox to share a file or a secret. A panel opens in the conversation.
- Pick the file or type the secret in the panel. It's encrypted in your browser before it leaves.
- Copy the link for each person. Links can be locked to their email, expire, and open a set number of times.
The assistant never sees your file or secret through Lockbox. A file reaches the chat only if you click "Send to chat". Lockbox's servers store only encrypted data.
