Google App Engine SSL Configuration and Installation Guide

Head over to SSLTrust's CSR Generator, and generate a new CSR/Key pair.

Country Name (2 letter code) [AU]: Type in the 2 letter abbreviation for your country.
State or Province Name (full name) [Some-State]: Full name of the state
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Locality Name (eg, city) []: Complete name of the city, no abbreviations
Organization Name (eg, company) [Internet Widgits Pty Ltd]: If you are a business; Enter your legal entity name. If you're not a business, any value entered will not be used in your certificate.
Organizational Unit Name (eg, section) []: If you are a business; Write the appropriate division of your company. It is best to use something generic such as "IT".
Common Name (e.g. server FQDN or YOUR name) []: Enter your domain name
Email Address []: Enter your email address

Now, select the required root length and click on Generate CSR

You will now see your newly generated Private Key and CSR. Make sure to store both in a safe location as you will need them for further SSL Configuration.

Now, we need to order an SSL Certificate. If you visit our SSL Certificates List page, you will see options available, such as a low-cost domain-validated SSL or a wildcard SSL, which also secures the sub-domains.

If you require any assistance with selecting an SSL Certificate, please feel free to contact our sales team and they will be happy to assist.

1: Order the SSL and complete the checkout.

2: Once you have completed the SSL Certificate Purchase you can begin the configuration process. This can be started by going into your SSLTrust account and managing your recent purchase.

You then will need to click the Submit Configuration button to begin the configuration process.

3: You now need to paste in the CSR you generated using the OpenSSL library in the Ubuntu CLI. This includes the lines:

Select Other for your Web Server Type.

You will need to also enter the Site Administrator Contact Information.

This information is to be of the individual who is responsible to approve and SSL Certificate. If it is a business SSL, it needs to be a contact under the business.

The Technical Contact Information is the details of the individual responsible for the installation and management of the Certificate.
If you have ordered a business SSL, you will also be required to enter your business details. These should be the correct address and phone number and legal entity name. They will be required to be validated by the Certificate Authority, any mistakes will cause delays. More information on Business Validation can be found here.

4: Click Continue to go to the next Step. Here you need to select the Authentication Method to validate your domain name. This is required to prove you own the domain name and have permission to issue an SSL Certificate for the domain.

Select the method that will be the easiest for you to use; File-Based Authentication ( HTTP / HTTPS ), CNAME Based Authentication ( DNS ) or Certificate Approver Email.

If you have access to one of the listed emails, this can be the quickest method

Click Continue/Submit to finish the Configuration process.

After you complete the domain validation via your selected method, your SSL will be issued. If you ordered a Business SSL, you will need to wait for the Certificate Authority to complete the Business address and phone validation. If the validation has not progressed, or you have not received your Certificate after some time, please contact our support team so we can check on its status.

When your SSL Certificate has been issued, you will be emailed the Certificate Directly from the Certificate Authority. You can also download it from your SSLTrust Portal. Downloading it from the SSLTrust Portal is a good option as we format the certificate in an easy to use way.

SSLTrust's Free SSL Checker is a tool that allows you to test and validate the SSL/TLS certificates installed on websites. Simply enter a domain name and it will analyze the certificate, providing details like the issuer, expiration date, encryption strength, and whether the certificate is properly configured and trusted by major browsers and operating systems. In SSL tests, receiving an "A" rating typically signifies that the SSL certificate and its configuration meet high security standards.

The checker highlights any potential security issues or misconfigurations with the SSL implementation. This free tool makes it easy to verify if a website's SSL certificate is valid and secure, giving visitors confidence their connection is encrypted and their data is protected from eavesdroppers.

Additionally, you can also performed a detailed check which generates an actionable report with all the ins and out of your SSL Certificate. This includes Protocols, Ciphers, Vulnerabilities and much more.
