openssl_pkey_new always return false with alpine 3.17

Question

I'm trying to move from Alpine 3.16 to 3.17 which comes with a breaking change of OpenSSL from v1.1.1 to v3.x.

This method openssl_pkey_new always fails on Alpine 3.17 and is not able to apply key generation probably.

It looks like there is a need for valid openssl.cnf according to PHP documentation but can't find any valid example.

Env:

• Alpine 3.17
• OpenSSL 3.0.8
• PHP 8.1

Did someone face a similar issue and could guide me?

Thanks :)
