I have asp.net core application. It works well but we are going to use https then. What I have to do? Steps in local development and in production?

For example, in local the url is http://localhost:12345; but we want https://localhost:12345

update:

In production I am talking about hosting in IIS

  • Do you have a https cert for localhost? letsencrypt.org/docs/certificates-for-localhost – mjwills Jun 6 at 1:04
  • I guess no. But does every developer need to have his own https cert on his machine? Or a common one? – Bigeyes Jun 6 at 1:08

    Do you mean you need Enforce HTTPS in ASP.NET Core? – Xing Zou Jun 6 at 2:24
  • localhost https comes out of the box. if you mean while hosting, append the question with more information on where you are hosting – Neville Nazerane Jun 6 at 4:27
  • @NevilleNazerane, I am not sure your comment. In local dev, we don't use IIS Express, it is .net core + angular project. In production we host it on IIS I guess. – Bigeyes Jun 6 at 10:18

In local development, you don't have to change anything if you're using IIS to expose your service.

In IIS either

  • check 'require SSL' for your site under 'SSL settings'
  • or if you want to redirect http traffic to https; do NOT check 'require SSL', but add a redirect rule

Like so

<rule name="HTTP to HTTPS redirect" stopProcessing="true">
  <match url="(.*)" />
    <conditions>
      <add input="{HTTPS}" pattern="off" ignoreCase="true" />
    </conditions>
  <action type="Redirect" redirectType="Found" url="https://{HTTP_HOST}/{R:1}" />
</rule>
  • Do we have to install some cert etc, could you please share some images(snapshot)? – Bigeyes Jun 7 at 11:14
  • I can't beat the Microsoft docs for that: knowledge.digicert.com/solution/SO14335.html – Jesse de Wit Jun 7 at 11:20
  • On your development machine you can simply use http. No need to test against a https service. – Jesse de Wit Jun 7 at 11:20
