What is HTTPS in web apps?

The web app almost always uses HTTPS, which means that browsers will forbid it from making XHR or WebSockets requests to non-secure URLs. This is called Mixed Content Blocking. To communicate with the web app, the native app needs to provide a secure web service.

What is Mitm in a domain name?

By introducing a domain name instead of an IP address, you make it possible for an attacker to Man in the Middle (MitM) the DNS lookup and inject a response that points to a different IP address. The attacker can then pretend to be the local app and send fake responses back to the web app, which may compromise your account on the web app side, depending on how it is designed.

What is the difference between HTTPS and HTTPS?

The main difference: On an HTTPS page, any requests to load JavaScript from an HTTP URL will be blocked. So if you’re developing locally using HTTP, you might add a script tag that works fine on your development machine, but breaks when you deploy to your HTTPS production site.

Is 127.0.0.1:8000/ a trusted URL?

Fortunately, modern browsers consider http://127.0.0.1:8000/ to be a “potentially trustworthy” URL because it refers to a loopback address. Traffic sent to 127.0.0.1 is guaranteed not to leave your machine, and so is considered automatically secure against network interception. That means if your web app is HTTPS, and you offer a native app web service on 127.0.0.1, the two can happily communicate via XHR. Unfortunately, localhost doesn’t yet get the same treatment . Also, WebSockets don’t get this treatment for either name.

Does MitM work with native app?

The successful MitM in this situation is possible because in order to make it work, you had to ship the private key to your certificate with your native app. That means that anybody who downloads your native app gets a copy of the private key, including the attacker.

Can native apps have certificates revoked?

Many native apps have had their certificates revoked for shipping their private key. Unfortunately, this leaves native apps without a lot of good, secure options to communicate with their corresponding web site. And the situation may get trickier in the future if browsers further tighten access to localhost from the web.

Can you use minica to generate a root certificate?

If you want a little more realism in your development certificates, you can use minica to generate your own local root certificate, and issue end-entity (aka leaf) certificates signed by it. You would then import the root certificate rather than a self-signed end-entity certificate.

Does Certbot work on Linux?

How to set up HTTPS for free?

Often, all that is required is for you to log into the site's control panel and enable it by ticking a checkbox or something like that. If so, you do not need to do any of the things mentioned here. In fact, if the web host already provides access to the free Let's Encrypt certificates, it is usually much easier to just use their implementation, since it means that they will automatically renew the certificate when it is near its expiry date, and install it for you.

What is the free software for Let's Encrypt?

How to test if a folder is in the correct place?

Test that you have created the folders in the correct place by connecting to your website in a browser. For example, if your site is www.example.com, type " http://www.example.com/.well-known/acme-challenge/ " (without the quotation marks) into the browser's address bar. The browser should show you an empty directory, or a "Forbidden" error (depending on whether your site is set up to show directory listings ). If so, go to the next step.

What does it mean when you get a file not found?

If you get a "File Not Found" message, or words to that effect, it means that you have created the folder in the wrong location. (Alternatively, you could also have named the folder wrongly, or perhaps even made a typo when you typed the address into your browser.) Return to step 1 and fix the error before continuing.
