My answer there is: "WinSCP cannot sign file with PGP."

I'm new to this SFTP and PGP thing. In my research, I found this other post on WinSCP about it: https://winscp.net/forum/viewtopic.php?t=14628.

I tried to provide all the details and requirements in my original post. Sorry if I'm not clear or perhaps I do not understand the requirements myself. Please let me know if you have any other questions.

WinSCP does not support PGP. Where did you read that?

I've read that WinSCP does encrypt with PGP, but can it still work in the following situation?
Vendor Requirements:
I have been asked to complete the following requirements:
1. Client supplies public SSH key.
a. Keys must be RSA format (2048-4096 bit, 2048 recommended).
2. If client is planning on extracting information out of Concur we will also need a public PGP key.
a. PGP public key must be formatted as OpenPGP (version 4)
b. ASCII-armored keys are supported
c. You will need to have a public signing key, and an encryption sub-key (this is the default generated by GnuPG, for example)
d. Keys should be either DSS/ElGamal (1024-3072 bit, 2048 recommended) or RSA type 1 (sign and encrypt, 1024-4096 bit, 2048 recommended)
e. Set key to never expire

My requirements:
Ultimately, I need to automate the following process: access their SFTP server, extract the file, and download it to a local file where I will run other automation on it.
