TCPEncryptedServer

Intended to be a TCP SECURE communications server in order to interperate TCP traffic as commands to be ran on a Linux system. E.g. An app from a phone could be used to adjust volume, shutdown/sleep pc, turn off monitors, etc...

In essence, this is a bog standard TCP socket listener with middle layer encryption and decryption functionality, using openssl; a long winded way of not using CSR lol.

New private/public keys should be generated, if secure usage is intended, with openssl genrsa -out private.pem 2048 to generate private key and openssl rsa -in private.pem -pubout -out public.pem to devise the public key.

Dependencies

openssl-1.1.1

TODO

Create functionality to encrypt/decrypt input.

Create TCP Socket for communications.

Enforce RSA Encryption to prevent eavesdropping.

Allow for pointing to pem files.

Create client counter part.

Compile Instructions

git clone "..."
cd TCPEncryptedServer
make release
bin/Release/TCPEncryptedServer

Bugs

When decrypting base64 sometimes random text will be dumped into the terminal. Possible unsafe read.
