Catching com.jcraft.jsch.JSchException: Algorithm negotiation fail

[Former Member]

Hi,

I received Algorithm negotiation fail error when trying to connect to External SFTP server.

External server told that SAP PI key exchange algorithm need to be changed to any of the below for successful connection.

DH_GROUP_EXCHANGE_SHA256

ECDH_NISTP256

I ran the SFTP trace and found the same issue. Where can we change the key exchange algorithm settings in SAP PI to reflect to any of above more secure key exchange algorithms.

I do not think upgrade to latest patch is required. as we are in SAP 7.4. SFTP adapter version is 4, path 18.

Thanks!!!
