We already moved away from 2048-MODP in Core Update 170. Similarly, German Federal Office for Information Security (BSI) recommends shifting away from RSA keys below 3,000 bits by the end of 2022 at the latest. The only place left in IPFire 2.x where we generate such keys is for IPsec and OpenVPN host certificates. This patch increases their key sizes to 4,096 bits as well - CA certificates already have this length. Existing VPN connections cannot be migrated automatically. However, only the respective host certificate has to be regenerated - thanks to the CA certificates' key length being sufficient, there is no need to replace the entire VPN CA.
