securChat vs VeliKey Messenger

SecureChat is a decentralized, encrypted messaging application built on the Nostr protocol. Features: • End-to-end encrypted messaging • Works seamlessly on your iPhone, iPad, and other devices • QR code scanning for adding contacts • Push notifications for messages • Decentralized architecture using Nostr relays • Privacy-focused design Stay connected with friends and family through secure, private conversations that put your privacy first.

VeliKey Messenger is private 1:1 messaging with end-to-end encryption you don't have to think about. • End-to-end encrypted. Messages are encrypted on your device and can only be read by you and the person you're talking to. • Forward secrecy. Every message uses a fresh key (X3DH + Double Ratchet), so a key compromise can't unlock your past conversations. • Minimal retention. The server stores messages only as opaque ciphertext until they're delivered, then deletes them. No plaintext, ever. • No account, no tracking. No phone number or email required. Add a contact by scanning their QR code in person (or sharing a contact code). No ads, no analytics SDKs, no contact-list upload. • Built on VeliKey Aegis. Messenger is a working demonstration of provider-managed cryptography: the operator can upgrade the whole fleet's cipher suites centrally, with staged rollouts, without an app update. VeliKey Messenger is an early release from VeliKey Technologies.
