Suricata

As clients begin migrating to PQC, such as the latest versions of Chrome and Golang which now use the Kyber KEM, many of our SNI-based rules have stopped functioning.

Example rule:
pass tls any any -> any any (msg:"Allow connection to test.openquantumsafe.org/"; flow:to_server,established; tls.sni;content:"test.openquantumsafe.org"; nocase; isdataat:!1,relative; sid:1;)
rejectboth tls any any -> any any (msg:"Unauthorized TLS outbound connection in any"; flow:to_server,established; sid:2;)

Example request: curl --verbose --curves kyber768:X25519 https://test.openquantumsafe.org/
Note :Communication works if I don't overwrite the curve
