An event-based and multi-threaded hybrid server with SSL implementation.

Hybrid Server

Introduction

Setup

Dependencies

Coded with boost version 1.62 (From version 1.66 io_service class is changed to io_context) apt install make g++ libboost-all-dev sqlite3 libsqlite3-dev libjsoncpp-dev libcppnetlib-dev openssl

Compilation

make

SSL Setup

1. DHPARAM File - for key exchange (Diffie-Hellman) openssl dhparam -out dhparam4096.pem 4096
2. Generate a private key and csr for CA openssl req -new -newkey rsa:4096 -nodes -out ca.csr -keyout ca.key
3. Generate a self-signed certificate for CA openssl x509 -signkey ca.key -in ca.csr -req -days 365 -out ca.crt
4. Generate server private key and certificate request

openssl genrsa -out server.key 1024
openssl req -new -key server.key -out server.csr

5. Sign certificate with CA and generate public certificate for server openssl x509 -req -days 365 -in server.csr -out server.crt -CA ca.crt -CAkey ca.key -set_serial 01
6. Make a chain file with CA and server public certificates to use it later in client cat server.crt ca.crt > ca-chain.cert.pem

Database Setup

Enter postgreSQL shell with the postgres user $ sudo -u postgres psql Create new user with createdb permission postgres=# CREATE USER repomaster WITH password 'repomaster' CREATEDB;
