Is your feature request related to a problem? Please describe.

It's more like a question if it's possible, if not, then that would be a RFE
Is it possible to generate RSA type cert instead of ECC.

Describe the solution you'd like

It would be nice to have this feature to select RSA or ECC in npm

Describe alternatives you've considered

Currently I am using Certbot to generate the RSA cert via Let's Encrypt and it's working fine.

Just docker override this file /etc/letsencrypt.ini copy repo one (docker/rootfs/etc/letsencrypt.ini) and change key-type to rsa, comment the elliptic-curve line and add rsa-key-size = 4096 (or what ever the size you prefer. This is mine and it works, generates RSA 4096 for all domains. It would be nice, if this would be a per cert thing, but this works as well.

text = True
non-interactive = True
webroot-path = /data/letsencrypt-acme-challenge
key-type = rsa
rsa-key-size = 4096

preferred-chain = ISRG Root X1

You can use this one. Be sure to mount is as :ro

/your-path-to/letsencrypt.ini:/etc/letsencrypt.ini:ro
