Cryptgeon

Cryptgeon is a privacy-focused, open-source alternative to services like PrivNote, designed for sharing sensitive information securely. Built with a zero-knowledge architecture, it ensures that all encryption happens client-side in your browser, making it impossible for anyone - including server administrators - to access your unencrypted data. Messages self-destruct based on configurable rules, preventing sensitive information from lingering online.

Common Use Cases

Security teams use Cryptgeon to share passwords, API keys, and sensitive credentials with colleagues without leaving a permanent digital trail. Healthcare professionals leverage it to share patient information temporarily while maintaining HIPAA compliance through encryption and automatic deletion. Legal departments utilize it for sharing confidential documents with automatic expiration to ensure sensitive case information doesn't persist. IT administrators deploy it for secure transmission of configuration files, access tokens, and system credentials during onboarding or support sessions.
