Symptoms

We read the files from bank FTP server using SOA FTP adapter. THey have reduced the list of ciphers and MAC algorithms. The only accept following ciphers - aes-256-ctr, aes-192-ctr and aes-128-ctr. The accepted value for MAC algorithms is hmac-sha256, hmac-sha2-256 and hmac-sha2-512. We made the changes in FTP connection factory as required and changed the following parameter values -

PreferredCipherSuite - aes-256-ctr
PreferredDataIntegrityAlgorithm - hmac-sha256

After making the changes we are unable to read the files from SFTP server. We could see the following message in the logs -

[composite_name: <COMPOSITE_NAME>] [composite_version: 1.0] [service_name: <SERVICE_NAME>] Exception while setting up session
