Cryptgeon is a secure, open-source note and file sharing service inspired by PrivNote, built with Rust and Svelte. Notes are encrypted client-side with AES-GCM, stored in memory only, and self-destruct after view or time limits; it ships as a self-hostable server, web app, and CLI client.

Use cases

• share a self-destructing secret note
• send sensitive files with a one-time link
• self-host a privnote alternative
• share passwords securely with expiration
• send encrypted notes from the command line
• share secrets without the server being able to read them

When to choose

• you need ephemeral, zero-knowledge sharing of text or files
• you want to self-host a PrivNote-like service
• you need view-count or time-limited secret links
• you want a CLI for scripted secret sharing

When to avoid

• you need persistent, long-term document storage
• you require guaranteed view limits across multiple server instances behind shared Redis
• you need compliance-grade audit logging or access controls
