Workspace DataPower Gateway

DataPower does not currently support rsa-sha2-256,rsa-sha2-512 on the FrontSideHandler for SFTP, but rather only rsa-sha.

Key encryption algorithms are not supported, yet we have clients moving to new algorithms, and disabling the older, meaning we would be unable to connect. This would ultimately force us to move away from datapower for this service. Specifically for FrontSideHandler for SFTP on Datapower MultiProtocolGateway.
"SSH Connector host key algorithms updated - added rsa-sha2-256 and rsa-sha2-512. Algorithms rsa-sha2-256 and rsa-sha2-512 are considered more secure than ssh-rsa . The reason is that the SHA-1 hash algorithm used in the ssh-rsa is cryptographically broken, so SHA-1 was replaced with SHA-2 ."
This is for Physical device, Firmware level IDG.

    Support for rsa-sha2-256 and rsa-sha2-512 hostkey algorithms has been added in the current Continuous Delivery (CD) release.(10.5.1)

    This support is targeted to be included in the next major Long Term Support (LTS) firmware release.
