Does AWS Application Load Balancer Support TLS 1.3?

Question

I am Trying To Search On google but I can not finding any A.W.S documentation regarding TLS 1.3

Answer 1

TLS 1.3 support in the Network Load Balancer has just been announced, so I think it's reasonable to expect that the new TLS 1.3 policies, such as ELBSecurityPolicy-TLS13-1-2-2021-06, will also be available on Application Load Balancers in a few weeks.

Update 2023-03-23: turned out to be more than a few weeks, but it's been announced today. The available policies, e.g. ELBSecurityPolicy-TLS13-1-2-2021-06 are documented here.

Answer 2

It does not support it. The supported versions are listed here.
