IOS openvpn won't connect due to encryption & PolarSSL: erroe

[xmatic]

Hi folks, complete noob here so please don't mind me if I sound like a complete idiot. I've been racking my brain and can't seem to get this for the life of me. I've spent an entire day reading, experimenting and trying everything to get this to work but nothing. I am trying to setup a private vpn on my pi zero. I followed this guy's tutorial https://www.youtube.com/watch?v=7a5CccDnhC8 and was successful in creating an encrypted key. It seems I can connect to my vpn via an app on mac os, but when I try importing the key profile into openvpn ios i get the following error message:

I've read extensively and found that it seems it has something to do in the way the private key was encrypted and not supported by openvpn on ios and I would have to manually change it to the 3des encryption format. I tried following the steps found here https://github.com/pivpn/pivpn/issues/171 but I don't know where and how to execute these commands. Is it under terminal? am I doing some special cmd on openssl? I mean i'm a complete noob when it comes to linux, I'm pretty comfortable with pc and mac, but this is kicking my ass. Everytime I tried executing any of these commands it would say not found or error. Any help would be greatly appreciated!!

I followed this guy's tutorial ...

Don't follow that .. start here:
HOWTO: For OpenVPN Community Edition

and was successful in creating an encrypted key

You may have a key but it clearly is not a working one.

I mean i'm a complete noob when it comes to linux, I'm pretty comfortable with pc and mac

You have a Pi so you better learn Linux now.

This is also a good place to start:

For your specific issue I would recommend using the latest Easy-RSA 3:
https://github.com/OpenVPN/easy-rsa/releases

A lot has changed regarding security recently and it may be that you have an old setting somewhere.
