Show HN: Raven – Encrypted messages hidden inside ordinary text

Solo developer OAraLabs released Raven, an encrypted messaging app that hides ciphertext inside ordinary text and stores it on the Solana blockchain, with a white paper and open-source core available. The app encrypts text on-device, uses pairwise keys with no accounts, and is available for iOS and Chrome, though it has not been audited and the relayer is run by the developer.

Solo dev. built in my spare time. Raven uses a combination of steganography and cryptography to create a metadata resistant messenger. It encrypts any piece of text on your device and stores the ciphertext on Solana. It works pairwise with keys, users decrypt locally on their device- no accounts. I do run the relayer and a retention sweeper not claiming peer to peer . One more thing, every write is signed by the same pool wallet, so anyone can see volume/timing. Check the white paper below and there’s been no audit. Several variations include: public, private, and stealth for fun, i’ve hidden a public raven in this post White Paper: https://oara.ai/raven-whitepaper https://oara.ai/raven-whitepaper The crypto and encoding core is open source.
