Support for GCM ciphers for SSH/(S)FTP connections - edtFTPj/PRO

Question

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.

Comments

I would like to ask if EDT can revisit this request.

We have a customer who is using our product to connect to JP Morgan (US bank). We just found out through our customer that JP Morgan (using Axway Secure Client)  will be ending support for aes-ctr SSH ciphers by June 21, 2025.

Announcement can be found here: https://www.jpmorgan.com/payments/client-resource-center/h2h/sssupport

Edit:
AWS also drops support for aes-ctr as per their latest TransferSFTPConnectorSecurityPolicy. You can argue that TransferSFTPConnectorSecurityPolicy-2024-03 is still their default policy, but there is no telling when they will default to the latest one. Link here: https://docs.aws.amazon.com/transfer/latest/userguide/security-policies-connectors.html

Thank you.

We don't have an ETA , but it should be in the next month or so.
