Encrypt file without modules PI or XI

Hi folks,

We are doing the integration between Success Factors and SAP HCM (on-premise), one of the requirements from the business is to encrypt the output files.

We are using the SAP Add-On SuccessFactors BizX to integrate the systems, the step by step is:

1. First, we execute the reports HRSFI_SYNCH_EMP_DATA or HRSFI_EMP_DATA_REPL to send the information of Employee Profile.
2. This information is sent to a SFTP server. Here the client request to have an encrypted file.
3. Then, SFSF is able to read the information and upload the information on the cloud.

We have checked and SFSF support DSA and RSA encryption methods, which create a file with a public key. But the issue is from the on-premise side because we don’t know how to encrypt the file…the client doesn’t have PI/XI module.

Somebody know about any encryption method supported to integrate SFSF ? any BADI, Function Module, and so on.

Regards,
