Decrypting a PGP File from SFTP Server

Question

Problem

The client that I am working with is asking us to encrypt (Using PGP or GPG) files from marketing cloud and insert them onto an SFTP Server. Then, we should create a separate Node JS Application to grab the encrypted files and decrypt them. The problem I am running into is that I cannot find a suitable package so decrypt these files.

Things I've Tried While programs exist to decrypt PGP files, I cannot find a package within the node package manager to do this. I have tried using OpenPGP to decrypt these files but am unable to do so because Salesforce provides basic PGP encryption and not armored PGP encryption. I have also looking into GPG but that also did not provide any solution.

Has anyone run into a similar problem and were they able to find a solution to this?
