bitchat is a decentralized peer-to-peer messaging app that operates over Bluetooth mesh networks, enabling local group chats without the need for internet, servers, or phone numbers. It is designed with privacy and security in mind, offering encrypted private messages and channels alongside a public local chat that requires no registration.

Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the...
