## Building
### LINUX
- testované na Ubuntu 20.04.5

1. Inštalácia potrebných nástrojov
`sudo apt install cmake gcc libtool libssl-dev make ninja-build git -y`

2. Stiahnutie Open Quantum Safe OpenSSL repozitáru
`git clone --branch OQS-OpenSSL_1_1_1-stable https://github.com/open-quantum-safe/openssl.git`

3. Stiahnutie a inštalácia liboqs

`git clone --branch main https://github.com/open-quantum-safe/liboqs.git
cd liboqs
mkdir build && cd build
cmake -GNinja -DCMAKE_INSTALL_PREFIX=../../openssl/oqs ..
ninja
ninja install`

4. Build QS OpenSSL fork

`cd ./openssl
./Configure no-shared linux-x86_64 -DOQS_DEFAULT_GROUPS=\"kyber1024:p521_kyber1024:kyber90s1024:p521_kyber90s1024\" -lm
make -j 1
sudo make install
`
5. Vytvorenie CA kľúča a certifikátu

cd ./openssl/apps
./openssl req -x509 -new -newkey p256_dilithium2 -keyout p256_dilithium2_CA.key -out p256_dilithium2_CA.crt -nodes -subj "/CN=oqstest CA" -days 365 -config ./openssl.cnf

6. Vygenerovanie privátneho kľúča pre server
./openssl req -new -newkey p256_dilithium2 -keyout p256_dilithium2_srv.key -out p256_dilithium2_srv.csr -nodes -subj "/CN=localhost" -config ./openssl.cnf

7. Vygenerovanie certifikátu s CA podpisom pre server

./openssl x509 -req -in p256_dilithium2_srv.csr -out p256_dilithium2_srv.crt -CA p256_dilithium2_CA.crt -CAkey p256_dilithium2_CA.key -CAcreateserial -days 365

8. Spustenie serveru a klienta
./openssl s_server -cert p256_dilithium2_srv.crt -key p256_dilithium2_srv.key -www -tls1_3
./openssl s_client -groups kyber1024 -CAfile p256_dilithium2_CA.crt -connect localhost
