Key Questions Answered
How did Shopify automate TLS certificate provisioning?
Shopify automated TLS certificate provisioning through its Notary system, which uses API calls to request certificates from the certificate authority, verify domain ownership, and deliver the certificate/private key pair. This automation also includes automatic renewals, significantly reducing manual labor and errors.
What challenges did Shopify face with manual TLS certificate provisioning?
Shopify faced several challenges with manual TLS certificate provisioning, including labor-intensive updates, the need for additional IP addresses for new certificates, and the complexity of managing multiple domains within a single certificate. These issues became unsustainable as the number of merchants grew.
What is the role of Let’s Encrypt in Shopify's TLS strategy?
Let’s Encrypt is a non-profit certificate authority that provides free TLS certificates. Shopify has transitioned to using Let’s Encrypt for most of its certificates, which has helped reduce costs and simplify the provisioning process, especially after the service launched in April 2016.
How did Shopify handle mixed content warnings on storefronts?
To resolve mixed content warnings, Shopify processed all shop themes to replace HTTP references with HTTPS. This ensured that all resources on the page were encrypted, thus providing a secure experience for users and eliminating browser warnings.
