Question

Как предоставить доступ ASP.NET к закрытому ключу в сертификате в хранилище сертификатов?

В Postgresql:

select *
from comments
where id in (1,3,2,4)
order by position(id::text in '1,3,2,4')

Хотя я посетил вышеупомянутое, я приехал в эту точку после многих попыток. 1-, Если Вы хотите получить доступ к сертификату от хранилища, можно сделать это как пример 2-, Это намного легче и более чисто, чтобы произвести сертификат и использовать его через путь
