S3 managed key (SSE-S3) rotation period

Hi Isaac,

I find this table good to explain the difference between the types of keys https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#key-mgmt

To be brief, AWS doesn't have a published frequency to rotate the keys used in SSE-S3. If you want to assure key rotation for compliance reasons you should look into AWS managed or Customer Managed (every 365 days if enabled). Alternative you can rotate manually if you want deeper control on this https://docs.aws.amazon.com/kms/latest/developerguide/rotate-keys.html#rotate-keys-manually

Hope this helps!
