Retyc CLI

Official command-line interface for Retyc - send transfers and manage datarooms directly from your terminal. With RetycFS, mount your datarooms as a local folder on Linux. Also runs as a local MCP server: connect your AI agent and control Retyc in plain language.

What is Retyc?

Retyc is a European sovereign file-sharing platform with end-to-end post-quantum encryption. Data stays in Europe, GDPR-compliant by design.

retyc-cli lets you integrate Retyc transfers and datarooms into your scripts, pipelines, and workflows - no browser required.

Security

• Authentication: OIDC device flow (no password ever stored locally)
• File data + metadata: end-to-end encrypted with AGE post-quantum hybrid keys
• Private key caching (Linux only): the decrypted AGE identity is stored in the kernel session keyring and is never written to disk. It is scoped to the current terminal session, isolated from other users and sessions, and uses a sliding TTL (default: 60 seconds). Each access refreshes the expiration timer.
• Transport: TLS enforced by default
