OpenWRT: OPKG installs the openvpn-easy-rsa package without the PKI generation scripts. How to decide?

Question

openvpn

Good day, friends!
I'm trying to file an OpenVPN server on Keenetic Omni with OpenWRT on board.
It seems to be nothing complicated if OPKG normally installed the openssl-easy-rsa package.
The fact is that in the folder with the package there is not a single script for generating keys.
Can someone tell me where to dig?
PS Do not offer to generate PKI on a third-party machine.

Answer 1

In general, you expressed quite a sound idea about the generation on a more suitable device :)
Why do you need a package? EasyRSA is perfectly cloned directly from the repository and does not require any compilation as far as I know.

Answer 2

so everything is done through /usr/sbin/easyrsa with parameters.
for example easyrsa build-ca.
