Storage

Based on:

The CloudFront distribution requires a public key for signature verification.

Generate a 2048 bit RSA key:

openssl genrsa -des3 -out private.pem 2048

Export the public key to a file:

openssl rsa -in private.pem -outform PEM -pubout -out public.pem

Open the public.pem file and ensure that it starts with -----BEGIN PUBLIC KEY-----. This is how you know that this file is the public key of the pair and not a private key.

Add the public key to the CDK infrastructure configuration.

Add the private key to the server configuration settings (JSON, AWS Parameter Store, etc).
