Query minimum RSA key size?

[Felipe Gasper]

Hello,

        OpenSSL 1.1.0k introduced behaviour that rejects 1,024-bit RSA key 
sizes.

        Is the new minimum key size queryable? It appears to be 2,048, but in 
the event that that changes again I’d ideally love just to grab that value from 
OpenSSL itself rather than hard-coding it.

        Thank you!

cheers,
