Encryption and Digital Signature with SFTP Adapter

Dear All,

There is a requirement in which digital signature has to be used to encrypt the data. So there are 2 steps:

Encrypt the data and digital signature has to be applied.

Scenario:

Sensitive financial information has to be sent in txt format from AL11 SAP directory to the shared folder (present in the target system) in our landscape. The target system tool would pick the file from the shared folder and process it further in the tool (file is moved within firewall i.,e file is not sent outside client network)

Please let me know the standard process and steps how we can achieve this through SFTP adapter.

Thanks,

Ankit
