The problem Stealth Sphere solves

StealthSphere provides a platform for fully secured messaging on Ethereum with End-To-End encryption. The sender can encrypt a message that can only be decrypted by the intended recipient. For encryption and decryption, a PGP key pair is used and not the Ethereum private and public keys are not used; thus, there is no threat of private key exposure.

Challenges I ran into

I had some doubts about implementing encryption during the project ideation phase, which was resolved after having a great chat with my mentor. The project integration was a nightmare as I only had a little experience in frontend development. The only option was tackling the errors one at a time and rigorous doc reading. For designing and integration, I also took some guidance from my university friends. Overall the project was a great learning experience.
