Advanctco PGP Decryption in SAP PI7.1

Hi,

We are integrating ECC and third party system with SAP 7.1. The requirement is to encrypt the Outbound to SAP message in CSV File format to third party using ADVANTCO PGP Encryption with Public key shared by third party.I have done Encryption part successfully in PI and third party is able to decrypt the message. Now i have issue with Decryption part, unable to decrypt the message , which is encrypted with PI Public Key shared to third party. I am trying to decrypt the message using PI private Key associated with PI Public Key shared to Third party.

When i check the payload in MONI, i still see the encrypted part only. The encrypted payload is having extension .csv.pgp. Any suggestions would be a great help.

Kind Regards,

Nitin
