Cisco Device HMAC Error

Open dfraire115 opened this issue 2 years ago • 1 comments

Using Posh-SSH version 3.1.3, I'm aware that versions 3.1.1 and above now use the 2023 SSH.Net Library. This library lists support for the MAC algorithm hmac-sha2-512. I'm attempting to create a New-SSHSession to a Cisco device, the device is configured to use hmac-sha2-512. The cmdlet fails citing a MAC error, when I manually change the hmac on the Cisco device to use hmac-sha2-256 the session is created successfully. Is the 512 hmac algo not supported or is this an issue specific to Cisco devices?
