Post Quantum SSH Key Exchange Algorithms

[Bryce Larson]

When doing git clones, pulls, pushes, etc. I'm getting this warning:

```

** WARNING: connection is not using a post-quantum key exchange algorithm.
** This session may be vulnerable to "store now, decrypt later" attacks.
** The server may need to be upgraded. See https://openssh.com/pq.html
```

This leads me to believe that bitbucket servers don't support post quantum key exchange algorithms for ssh access to git.  Can we get that added soon?

I just received this same message too.  Running EndeavourOS Arch Linux on my dev machine and it just upgraded to OpenSSH 10. 

[16:05:01] [hubbaba ~/dev/RampantStrategy(develop)] ➜ ssh -V 
OpenSSH_10.2p1, OpenSSL 3.6.0 1 Oct 2025

This is going to start becoming a common message that people are going to see, so I'd suggest adding it to the roadmap.  Seeing a big warning sign every time I commit just makes me nervous.

Hi @Bryce Larson 

I don't have any special insight into the Bitbucket roadmap; it might already be in progress.

It doesn't look like anyone has opened a feature request ticket, if only to be able to watch it age over the years. I would certainly upvote such a feature.
