## Библиотека для ширования подписи на WASM
Готовый шаблон тестов есть в example.html
Ваша задача фундаментально такая:
1) сгенерировать подпись
2) отправить подпись на эндпоинт нужным образом
Как сгенерировать подпись?
1) в метод get_secret_value сунуть:
- user_agent (че угодно)
- cur_time (время из эндпоинта https://api.id.hublab.ru/api/v1/server-timestamp )
- url (на самом деле это path)
Формат подписи: набор букв и чисел. Если в результате будет что-то типа "Ошибка 95d19684-e70e-47f5-9341-94f5fd575d08", то значит
что-то пошло не так. Отправить такую подпись вы можете, но бэк её не свалидирует и вернёт 401))
