What is the difference between the certificates in the `standalone/letsencrypt` folder the `standalone/ssl` folders?

In the letsencrypt folder I see two sub folders for the site with certificates, one with the _sitename_ (RSA) and other with the _sitename\_ecc_ ([ECC](https://blog.dnsimple.com/2022/12/ecc-support-for-letsencrypt-certificates/))

Then I see another `ssl` folder which also seems to have `.key` and `.cer` certificates with the same names the certificate in the letsencrypt _sitename_ and _sitename\_ecc_ folders.

However, **the timestamps of all the files in the ssl folder and different from the timestamps in the letsencrypt folders and importantly the `.cer` certificate file sizes in the ssl folder are different from the file sizes of `.cer` files in the letsencrypt folders**.

So my questions are:

- what’s the difference between the files in the ssl and letsencrypt folders
- which one is used by discourse
- if the folders in the ssl folder are corrupted/deleted can they be replaced with the files from the letsencrypt folder? (this is important because I ran into a situation where while restoring a site, letsencrypt was unable to get replacement certificates due to excessive restores but I had a valid copy of working certificates from the letsencrypt folder from an image backup).
