Re: PuTTY is outdated
We will definitely update WinSCP to PuTTY 0.78.
Is there any specific new feature of PuTTY 0.78 you are after?

Re: PuTTY is outdated
Hi Martin,
indeed there are exciting changes! I have tried the new PuTTY with Kinetic Kudo and OpenSSH 9.x for the new "sntrup761x25519-sha512@openssh.com". It is a crypto nerd's fantasy, but I am excited to have it deployed soon in WinSCP too!
Many good important changes:
Support for OpenSSH certificates, for both user authentication keys and host keys.
Support for NTRU Prime post-quantum key exchange,
Support for AES-GCM (in the OpenSSH style rather than RFC 5647).
I know there won't be a quantum computer that can break >2048 bit key exchanges in the near future, but libraries/dependencies being up to date is good.
Just really excited ;)
Thanks for your work as always, sir!

be updated to do conversions including adding an OpenSSH certificate (like I can now do in PuTTYgen), so that the work can be scripted?
Thanks!

Re: PuTTY is outdated
NTRU and AES-GCM should come with update to PuTTY 0.78 without more effort.
The OpenSSH certificates might need further effort on WinSCP side. The
Support for OpenSSH certificates is tracked here:

Re: PuTTY is outdated
Are you using the certificates for user authentication only? Or also for verifying the hosts?
