Certificate

As explained in Build Python Web Apps with Streamlit

A digital certificate is a digitally signed document that binds a domain or other identity to a public key for authentication and encrypted communication.

A digital certificate is an identity document for a website. It proves that a server is authorized to use a domain and lets a browser establish HTTPS, encrypting communication between users and the app. A trusted Certificate Authority issues the certificate after verifying domain ownership. section 12.4.2

Enable a certificate for a deployed app by completing these steps:

• Use a custom domain rather than the default Elastic Beanstalk domain, because a Certificate Authority cannot verify control of Amazon’s default domain. section 12.4.1
• Request a public certificate in AWS Certificate Manager for the app’s fully qualified domain name, then add the supplied CNAME records to DNS to prove ownership. section 12.4.2
• Attach the issued certificate to the Elastic Beanstalk load balancer by adding an HTTPS listener on port 443. section 12.4.3

Securing a deployed Streamlit app

For www.factfrenzyapp.com, request a public certificate in AWS Certificate Manager, validate ownership with the displayed DNS CNAME record, and select the issued certificate when adding an HTTPS listener on port 443. The browser can then confirm that the connection is secure. section 12.4.2 section 12.4.3

How Build Python Web Apps with Streamlit covers it

How deep it goes

Explains website identity, domain validation, certificate requests, and listener configuration, but defers single-instance HTTPS setup.

Examples

Uses www.factfrenzyapp.com, DNS CNAME validation, AWS Certificate Manager, and a port-443 load-balancer listener.

What it assumes

Assumes a deployed load-balanced Elastic Beanstalk app and a custom domain whose ownership can be verified through DNS.

What you can do after

Operate/configure AWS Certificate Manager and Elastic Beanstalk to issue and attach a certificate for HTTPS.

How it connects

Connects certificates with HTTPS, Certificate Authorities, DNS, custom domains, and load balancers.
