Thank You KamleshKumar and ColinDijkgraaf.
I did check with MS Support as well and they confirmed as below
Biztalk 2013 R2 SFTP adapter only supports hmac-sha1, hmac-sha1-96 and hmac-md5 MACs and KEX algorithms
This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
I am having open SFTP connection error [Exceptions.Types.DeliveryFailureException:Exceptions.Types.DeliveryFailureException ] from SFTP adapter in BizTalk 2013 R2.
This was working all good until there was an update on the SFTP server where certain MACs and KEX algorithms are restricted as part of the security updated and it allows only specific MACs and Kex Algorithms.
Is there a way to know or specify the MACs and Kex Algorithms with BizTalk 2013 R2 SFTP adapter.?
