SFTP Ciphers and Algorithms

Hi Experts,

Can someone please help me here...

We have a dual environment systems in place with PI 7.1 and PO 7.5. Now, some of our SFTP vendors are disabling the ciphers and MAC algorithms that do not meet their security standard for Advantco’s SFTP adapter. Is there a way how to identify all the SAP SFTP channels which had been used by any Ciphers/ Algorithms?

Also, please suggest "what kind of issues may occur" if the Ciphers /Algorithms didn't update in the system within the timeline?

Thanks,

Dileep
