#### Setup
On a macOS VM:
1. Generated a certificate with Cyrillic characters in CN and O fields:
```bash
openssl req -x509 -newkey rsa:2048 -keyout newkey.pem -out newcert.pem -days 365 -nodes -utf8 -subj "/CN=АБВГДЕЖЗИКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯа/O=АБВГДЕЖЗИКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯа"
```
2. Installed the certificate:
```bash
sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain newcert.pem
```
