SSL Certificate Installation on Heroku SSL

SSL Certificate Installation on Heroku SSL

Heroku is transitioning away from SSL Endpoints and introducing a new feature: Heroku SSL. Heroku SSL is a free feature that enables the management of SSL/TLS encryption for custom domains, utilizing the Server Name Indication (SNI). Please be aware that Heroku SSL is currently exclusively available under Heroku’s paid plans.

នៅពេលដែល ការធ្វើឱ្យសកម្ម និង សុពលភាព steps are completed, your certificate will be issued and you can proceed with the SSL installation. In order to install the ពួកគេផ្តល់វិញ្ញាបនបត្រ SSL via Heroku SSL, the following files should be used:

  • An issued SSL certificate file for your domain name, e.g. a file with a .crt or .pem extension.
  • នេះ CA Bundle file, which is a chain of certificates that is usually installed in order for browsers to verify that the certificate was issued by a trusted Certificate Authority, usually, it is provided with the certificate itself as the file with .ca-bundle extension. Once the certificate is issued, both certificate and its bundle can be បានទាញយក from your 1Byte account.
  • ដែលត្រូវគ្នា។ Private Key file with .key extension. Your Private key is generated along with the CSR code that was used to activate the certificate. (This resembles the CSR code and looks like some number of lines with random symbols.) This code starts with ‘—-BEGIN RSA PRIVATE KEY—–’ and ends with ‘—–END RSA PRIVATE KEY—–’ tags.
Please keep in mind that for Heroku, it’s necessary to combine the certificate and the CA Bundle into one file.
You can open the .crt and .ca-bundle files using any plain text editor, pasting the codes from the .ca-bundle file just below the code in .crt file. Make sure that there are no spaces between the codes.

In corresponding command line, you can combine the files using the following command:

cat yourcertificate.crt bundle.ca-bundle > server.crt

You can also create a combined file using this tool: https://decoder.link. Simply paste your certificate code in the box >> click on ឌិកូដ >> download the file in the Bundle (Nginx) វាល។

Installation via Heroku Dashboard

To install the certificate in your Heroku Dashboard, open the certificate, select the necessary application from the list, and select ការកំណត់.

Then, scroll down the page and click on កំណត់រចនាសម្ព័ន្ធ SSL in Domains and certificates ផ្នែក។

In the window that appears on your screen, select ដោយដៃ ពីបញ្ជីហើយចុច បន្ត. On the first screen, simply drag and drop the combined certificate + bundle file to the box and click បន្ត. After that, do the same with the Private Key file.

It’s also possible to paste the codes manually (using the paste the contents of the file directly option in the box). You can open the files with any text editor (like Notepad for Windows or TextEdit for Mac), copy the contents and paste them into the boxes.

Once done, Heroku will prompt you to update the DNS records of the custom domain/subdomain. You will need to create a CNAME record using the values displayed to you. The (ម្ចាស់ផ្ទះ value (‘Name’, etc.) is your domain/subdomain and the គោលដៅ value (‘Points to’, etc.) is yourdomain/subdomain.herokudns.com.

Basically, you need to follow this pattern:

yourdomain.com CNAME yourdomain.com.herokudns.com
or
www.yourdomain.com CNAME www.yourdomain.com.herokudns.com

After you made sure that the DNS is configured, click on ‘I’ve done this’ and then click on ‘Continue’. Please keep in mind that it may take some time for the DNS to be updated globally.

That’s it, your domain is now accessible via HTTPS. You can verify the installation by using ឧបករណ៍នេះ.

Installation via CLI

Another way to install the certificate is via the command line.

The process is pretty short. Upload the certificate + bundle (combined as described in តម្រូវការជាមុន section of this guide) and Private Key files to Heroku using the heroku certs:add server.crt server.key ពាក្យបញ្ជា។

In case when there is no default Heroku app, you will need to specify it as well using the –app flag, so the command will look like this: heroku certs:add server.crt server.key –app yourappname.

To check if the correct certificate is installed at the moment, you can run the heroku certs:info ពាក្យបញ្ជា។

Please note that you may get an ‘Internal server error’ message when adding your certificate. The reason may be that you are using an outdated version of the Heroku CLI. In this case, you can check your CLI installation and update it to the latest version with the heroku update command or reinstall the CLI itself.

ការដកវិញ្ញាបនប័ត្រចេញ

If you need to remove the certificate, it can be done via the same menu. Just navigate to Domains and certificates >> click កំណត់រចនាសម្ព័ន្ធ SSL >> ជ្រើសរើស យក >> click បន្ត >> enter the name of your app and click Remove SSL.

To remove the certificate using the command line, simply run the command heroku certs:remove and enter the app name for confirmation.

Updating Certificates

When you need to replace an installed certificate with another one (e.g. the certificates were reissued, you received a completely new certificate or it’s time to renew), the installation process will stay the exact same in the Heroku dashboard.

For command line, only one thing will differ: you will need to use the heroku certs:update command instead of heroku certs:add, so it will look like: heroku certs:update server.crt server.key.

Also, we recommend setting up the HTTPS redirect so that the website is accessible only via a secure HTTPS connection.

However, in case of Heroku, this setting will depend on the programming language, framework, and tools you used to build your app. There is no general way to set up the HTTPS redirect that will surely work on all apps.
