CodeCourier

Secure file sharing inside VS Code.
Encrypt locally, verify the sender, preview safely, and import only when you choose.

.codecourier packages • Signed shares • Approve before write

What It Does

CodeCourier helps developers share files securely from one VS Code workspace to another.

Instead of sending plain files and blindly writing incoming content into a project, CodeCourier packages the current file into an encrypted .codecourier file. The receiver can verify who sent it, preview the content, and decide whether to import it.

Where You See It In VS Code

CodeCourier is not only a Command Palette tool. It is also visible directly in the VS Code interface.

• Activity Bar icon: CodeCourier
• Side panel views: Overview, Recipients, Recent Activity
• Primary action: Secure Share Current File
• Available from commands and extension UI inside VS Code

This means you can open and use CodeCourier from the side panel, not just by typing commands manually.

Main Features

• Securely share files from inside VS Code
• Encrypt files locally before sending
• Verify the sender before importing
• Preview incoming content before writing to disk
• Import only when you approve
• Manage trusted recipients from the extension panel

• Trust is based on imported public identities
