Is there any plans/timeline as to when will GCM ciphers going to be supported for SSH connections? 

I am checking the documentation for SSHFTPAlgorithm

We have a couple of clients who are being required by their vendors to connect via SSH and use GCM ciphers, particularly aes128-gcm@openssh.com and aes256-gcm@openssh.com.

Thank you.

We aren't likely to support vendor specific ciphers like the @openssh.com ciphers.

Because of this, the recent Terrapin attack on the openssh.com ciphers didn't affect our products.

Hello, thank you for answering. How about support for standard GCM ciphers?  ie AES GCM

Interestingly, there aren't any standard GCM ciphers for SSH. The @openssh.com ciphers are the only ones we're aware of. I'm not sure why as GCM is used in TLS (and indeed we support it).
