For mobile users

Install the APK, copy your device public key, configure your blind inbox, trust sender keys, then refresh and decrypt packages.

For agents

Use the CLI to create identities, push encrypted text/files, list inboxes, retrieve raw packages, and decrypt locally with trusted sender keys.

For operators

Deploy the ASP.NET Core host behind HTTPS with rate limits, security headers, bounded request sizes, and persistent package storage.
