Hello,
I have seen that there is an FTP adapter in SAP XI. We currently have guidelines to use Secure FTP (SFTP) for FTP communication over an 'unsecure' network.
We would like at least 128bit encryption, preferably 1024bit key.
Can SAP XI also support this (and how)? Or is there a possibility with third party adapters?
Best regards
At this time, I do not believe XI supports secured FTP. XI only supports the FTP application within the TCP/IP stack.
Secured FTP is proprietary in its implementation, even though the encryption algorithms are standard.
In order to implement secured FTP, I believe an adapter would have to be developed, specific to the secured FTP application you are using.
Regards,
Bill

Hi Bill,
I am also, trying to use encryption to receive a flat file through FTP and by using the File adapter or a custom adapter if necessary in XI 3.0.
- What is the tool In XI 3.0 to develop an Adapter in order to use encryption?
- How does it get developed? Is it tied to the File adapter? Can you receive an encrypted file with the XI File adapter?
Thanks

While the File/FTP adapter does not support secure FTP, there are a couple of options for protecting FTP communications.
1. Develop a custom FTPS adapter. There are some good commercially-available Java libraries that implement FTPS; I've found the Secure FTP Bean from Glub Tech (www.glub.com) to be reliable and compatible with many common FTPS servers. It's called a bean, but it really is just a basic Java API library. (It's shareware -- free to download for prototyping, $500 for internal use.)
You do need to understand the various options in the FTPS specification to get this to work. Reading IETF RFC 2228 will help.
2. Use the FTP adapter, and encrypt/decrypt the file contents through a user exit in the adapter. Something on the FTP server side will have to do the same.

The SEEBURGER "VAN Access Adapter" for XI 3.0 which is mainy used for supporting various VAN access interfaces is also able to to scriptable secure FTP.
Not sure if this Service Marketplace URL works for you:

(look for netweaver in detail / process integration / exchnage infrastructure in detail / connectivity / xi 3.0 / seeburger /)
