VPN traffic FORTIGATE 300e

friend, a question: we are using SSL VPN on a fortigate 300E 6.0.11. I have gone through a lot of documentation and have not found a way to identify what encryption my device is using.

For an audit, I am asked to send a screenshot about "Encryption mechanism implemented for VPN traffic (ssl, ipsec, etc)", where do I locate the encryption implemented? vpn ssl setting in FORTIGATE? can you help me, I thank you
