Hi, This is Elias from Miami. I checked your project description and understand you’re looking to build a secure messaging app for iOS and Android with true end-to-end encryption, covering private text conversations and encrypted file sharing. I’ve worked on mobile apps with secure data handling and understand that for a product like this, the real priority is getting the encryption model, key management, and cross-platform messaging flow right from the start. My approach would be to build the app around a proven secure messaging architecture, with encrypted message/file transport, protected local storage, clean mobile UX, and a backend limited to delivery/orchestration so sensitive content stays private by design. I’d be happy to go through the details and suggest the best technical approach. I have a few questions to get a better understanding: Q1 – Do you want one-to-one messaging only in the first version, or should group chats be included as well? Q2 – For file sharing, what types and size limits do you expect to support in the initial release? Q3 – Do you want the app to use phone-number-based registration, email login, or another identity model? Looking forward to hearing from you.

Hello! We’re a team of mobile engineers with solid hands-on experience building secure, privacy-focused applications for both iOS and Android, including projects where data protection and encrypted communication were core requirements rather than add-ons. End-to-end encryption, secure file transfer, and careful handling of sensitive user data are areas we’ve worked with in real production environments, following modern security best practices and privacy regulations. For a messaging app like this, we would focus not only on implementing reliable text messaging and encrypted file sharing, but also on building a strong underlying architecture: key management, secure storage, encrypted transport, and protection against common attack vectors. Just as important is ensuring the app remains performant, stable, and intuitive while maintaining a high level of security behind the scenes. We would be happy to share examples of relevant work and discuss the approach we recommend for implementing end-to-end encryption in a scalable, maintainable way across both platforms. Looking forward to learning more about your vision for this app and how we can help bring it to life.

@techsty2014

Hi, I will build your encrypted messaging app for iOS and Android using Flutter for a shared codebase, with the Signal Protocol (Double Ratchet + X3DH key agreement) powering the end-to-end encryption for both text messages and file transfers. Messages will be encrypted on-device before they ever leave — the server will only relay ciphertext it cannot read. For file sharing, I will encrypt files client-side with AES-256, upload the encrypted blob to cloud storage, and share only the decryption key through the encrypted message channel. This keeps large files off the messaging server while maintaining full encryption. I will also implement key verification between users via QR code or safety number comparison, so users can confirm they are communicating with the right person and detect any man-in-the-middle scenarios. Questions: 1) Do you need group messaging in the initial release, or is one-to-one sufficient for MVP? 2) How should user registration work — phone number, email, or both? 3) Do you have specific compliance requirements (GDPR, HIPAA, or regional data residency)? You can check our mobile work here: StatStream and P2T Private on the Play Store. Looking forward to your response. Best regards, Faizan
