Description:

An end-to-end encrypted imageboard offers significant benefits in terms of privacy and security for users. With end-to-end encryption, all content, including images, messages, and posts, is encrypted on the sender’s side and can only be decrypted by the intended recipient, ensuring that no third parties, including the imageboard administrators or hackers, can access the information.

Features:

• End-to-end encryption for all user data
• Small codebase
• Server runs even on cheapest hardware
• Docker support
• Built in Rust
