Default encryption algorithm for SFTP without PGP

[Former Member]

Hi Experts,

We are planning to interface third party SFTP server by sending the files in secured manner(without PGP encryption). As per the standard SFTP adapter and SSH Protocol, connection and data are encrypted during the file transfer using secured tunnel.

Will the SFTP adapter use a default encryption if don't PGP encryption? Will SFTP use SSH server default encryption to encrypt data sent from SFTP adapter? we understand SFTP supports multiple encryption, But does SFTP use a default encryption when we are not using PGP encryption in Interface?

Please go through SAP Note: 2344454 which has the list of encryption algo (CIPHER) supported by SFTP adapter. But However i don't thik there is option in PI to select particular algo from one of those , this is usually identified by the SFTP server settings automatically.

Thanks!

We are looking SSH-Tunnel and do not want to go for PGP encryption. How does SFTP chooses the CIPHERS(encryption algorithm) for SSH-Tunnel?. Does SFTP calls for any specific CIPHERS or does it uses SSH default CIPHERS?

Hi Rosh ,

The encryption which you are talking is about SSH-Tunel with 3DES or other also and not the data, SFTP encrypts the "connection" between you and the server and later the data is transferred via that tunnel. If you want to actually encrypt the "data" that is being sent then you may go for PGP.

If you don't use PGP in addition to your SFTP, there will not be any "default message encryption". If you want your message to be encrypted as well (say a file which you want to be encrypted and sent to third party) then you need to add PGP encryption in addition to your SFTP communication.
