IPSEC VPN (Site to Site) using RSA Keys

[heyyo]

Hi,

Is it possible to use RSA keys for Site to Site IPSEC VPN set up? I am trying to look for KBs but unable to find one. 

Thank you!

generate RSA key pairs for both ends of the VPN. This can be done using tools like OpenSSL.

 Import the RSA public keys or certificates into the FortiGate devices. 

Then configure IPSEC VPN
