Nginx-gost

Инструкция по настройке nginx, отдающим страницы с кодированием по ГОСТ-2012.

1. Установка nginx:

# apt-get install nginx

2. Настройка OpenSSL

Подробно рассмотрено в статье ГОСТ в OpenSSL.

3. Создание ключей

• Создаём закрытый ключ по алгоритму ГОСТ:

$ openssl genpkey -algorithm gost2012_256 -pkeyopt paramset:A -out gost.example.com.key

• Создаём запрос:

$ openssl req -new  -md_gost12_256 -key gost.example.com.key -out gost.example.com.csr -subj "/C=RU/L=Moscow/O=My site with GOST/CN=gost.example.com"

• Подписываем запрос в УЦ, или подписываем запрос на сертификат своим "самоподписанным" ca.cer сертификатом и ключом ca.key (ГОСТ в OpenSSL):

$ openssl x509 -req -in gost.example.com.csr -CA ca.cer -CAkey ca.key -CAcreateserial -out gost.example.com.cer -days 5000

4. Создаём каталог /etc/nginx/ssl и копируем туда файлы gost.example.com.cer и gost.example.com.key:

# mkdir /etc/nginx/ssl
# cp /home/user/gost.example.com.cer  /etc/nginx/ssl/
# cp /home/user/gost.example.com.key  /etc/nginx/ssl/

5. Создаём файл конфигурации /etc/nginx/sites-available.d/gost.conf:

server {
        server_name gost.example.com;
        listen       443 ssl;
        ssl_certificate /etc/nginx/ssl/gost.example.com.cer;
        ssl_certificate_key /etc/nginx/ssl/gost.example.com.key;
        ssl_ciphers GOST2012-GOST8912-GOST8912:HIGH:MEDIUM;
        ssl_protocols   TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers  on;
        location / {
            proxy_pass http://gost.example.com;
        }
}

Примечание: В примере указано имя сервера gost.example.com. Укажите имя своего сервера.

6. Активируем конфигурацию:

# ln -s ../sites-available.d/default.conf /etc/nginx/sites-enabled.d/default.conf
# ln -s ../sites-available.d/gost.conf /etc/nginx/sites-enabled.d/gost.conf

7. Запускаем nginx:

#  systemctl start nginx

8. Проверяем подключение:

$ openssl s_client -connect gost.example.com:443
CONNECTED(00000003)
depth=0 C = RU, L = Moscow, O = My site with GOST, CN = gost.example.com
verify error:num=20:unable to get local issuer certificate

verify error:num=21:unable to verify the first certificate
verify return:1

Совет: для работы с таким сервером можно использовать elinks или chromium-gost:
