## 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
```

### WINDOWS
- testované na Windows 10.0.19043

**1. Príprava prostredia

Perl - stiahnutie Perl-u strawberry-perl-5.32.1.1-64bit zo stránky https://strawberryperl.com/

Cmake - stihnutie CMake-u cmake-3.26.3-windows-x86_64 zo stránky https://cmake.org/download/

Pridanie premenných prostredia:
```
D:\Strawberry\perl\bin
D:\Program Files\CMake\bin
```
pozn. v našom prípade premenná nepomohla a bolo nutné je nekonfigurovať manuálne v Powershelli príkazom
```
$env:path += ";D:\Program Files\cmake\bin"
```

**2. Stiahnutie OpenSSL, Open Quantum Safe OpenSSL repozitáru a liboqs**
OpenSSL - stiahnutie OpenSSL 1.1.1t zo stránky - https://www.openssl.org/source/
Stiahnutý súbor sme extrahovali do priečinka ProgramFiles a premenovali sme ho na openssl

OpenSSL OQS - stiahnutie OQS OpenSSL repozitáru z GITu - https://github.com/open-quantum-safe/openssl/tree/OQS-OpenSSL_1_1_1-stable
Presun stiahnutých súborov do openssl priečinku

Liboqs - stiahnutie súborov z GITu - https://github.com/open-quantum-safe/liboqs

**3. Príprava liboqs
- prípade chyby prístupu pri príkaze cmake alebo ninja je potrebné spustiť PowerShell ako administrátor
```
cd liboqs
mkdir build
cd build
cmake -GNinja -DCMAKE_INSTALL_PREFIX='D:\Program Files\openssl\openssl-OQS-OpenSSL_1_1_1-stable\oqs' ..
ninja
ninja install
```

**4. Build QS OpenSSL fork**
```
cd ./openssl
perl Configure VC-WIN64A no-shared
!!!nmake
```
