PI integration with SFTP/PGP encryption

Hi Guys,

I am getting a File from Third party SFTP with PGP encryption and needs to integrate with SAP system using PI 7.1

Can you please throw some light how to do this?

I just heard about Advantco SFTP adapter that needs to buy to do this? If so,how to decrypt the file which is coming with PGP encryption?

Thanks,

Srini.
