Tharindu,
I am official IFS Partner (Ahead ERP Consulting). We have a solution for you.
I have implemented the PGP Encryptor as Java transformer. This was done for IFS App 7, so it would have to be uplifted to your version (Apps 9? Apps 10?) and tested.
This was done to integrate IFS with JP Morgan/Chase for supplier (AP) payments using ACH, check or wires.
The way it was done, no one was touching the actual file all the way from IFS to the bank (file generated in IFS, PGP-encrypted by Java transformer, sent via SFTP sender, received by the bank, PGP-decrypted).
We can provide this solution. Let me know if you are interested (mateusz.klos@aheaderp.com).
