Cryptgeon

Overview:

cryptgeon is a secure, open source sharing note or file service that is inspired by PrivNote. It consists of a server, a web page, and a CLI (command-line interface) client. This service allows users to send encrypted text or files, and the server is unable to decrypt the contents due to client-side encryption. The data is stored in memory and is never persisted to disk, ensuring the privacy and security of the shared notes or files.

Features:

• Client-side Encryption: The notes or files are encrypted on the client side using AES in GCM mode with a generated key, ensuring that the server cannot decrypt the contents.
• View or Time Constraints: Users can set constraints on the notes or files, such as limiting the number of views or setting an expiration time.
• In-memory Storage: The data is stored in memory and is never persisted to disk, providing an extra layer of security.

Summary:

cryptgeon is a secure sharing note or file service that ensures the privacy and security of the shared content. With features such as client-side encryption, view or time constraints, and in-memory storage, users can safely share sensitive information without the risk of unauthorized access or data being persisted on the server. The installation process is straightforward, making it easy for users to set up and start using cryptgeon.
