Backend side of End-to-end encryption messaging app created with React Typescript and NodeTS

This app is a secure messaging application that provides application layer security, end-to-end encryption, and digital signatures. It is available for web and mobile-website.

Application layer security is implemented using Elliptic-curve Diffie–Hellman (ECDH) and Block Cipher to protect the communication between the client and the server.

End-to-end encryption is implemented using Elliptic Curve Cryptography (ECC) to ensure that only the sender and intended recipient can read the messages.

Digital signatures are used to verify the authenticity and integrity of messages. They are generated using the Schnorr signature scheme and are based on the content of the message and the signer's private key. Digital signatures can be viewed by the recipient but are not stored with the message. The recipient can also verify that the signature is valid, which proves that the message has not been tampered with and that it came from the claimed sender.

$ npm run dev

If you do it correctly, and set the environemnt using configuration in .env file (Example in .env.example), the pogram should be running on localhost:4000. Don't forget to run the frontend side also. Further explanation on how to run the frontend development server stated on this repository

In the project directory, you can run:

Ths runs the app in the development mode.

Ths runs database instance in the docker image.

The page will reload if you make edits.
You will also see any lint errors in the console. You can also use the environment by appyling the basic .env configuration on .env.example file.
