CPP Cryptographic service

I wanted to improve my CPP and Cryptography skills, so here is a POC for a CPP HTTP2 service that offers functionality for text messages encryption and decryption leveraging well known cryptographic algorithms.

Supported Algorithms

Currently only the Caesar algorithm is supported, it was used to bootstrap the project. Soon more algorithms will be implemented such as DES, AES, etc.

Used Technologies

• Docker: As platform tool.
• CPP: The project uses Boost, Nghttp2 as underlying HTTP/2 server and Google Test as unit test engine.
• CMAKE: As building tool.

How To:

Build it

You need to have docker installed on your machine.

Steps:

• scripts/buildBase.sh: It builds de cppcryptographicservicebase image, do it only once.
• scripts/build.sh: It will compile the code and build the cppcryptographicservice docker image that can be used to run the server.

Run and test it

Once that the image is build, you can run it with:

docker run -d -p 3000:3000 cppcryptographicservice:latest

And test the Caesar cipher encryption with:

curl -d '{"message":"This is a plain text message","key":"3"}' --http2-prior-knowledge localhost:3000/api/crypto/caesar/encrypt

And decryption:

curl -d '{"message":"Wklv lv d sodlq whaw phvvdjh","key":"3"}' --http2-prior-knowledge localhost:3000/api/crypto/caesar/decrypt
