Circumventing Deep Packet Inspection with Socat and rot13

I have a Linux virtual machine inside a customer's private network. For security, this VM is reachable only via VPN + Citrix + Windows + a Windows SSH client (eg PuTTY). I am tasked to ensure this Citrix design is secure, and users can not access their Linux VM's or other resources on the internal private network in any way outside of using Citrix.

The VM can access the internet. This task should be easy. The VM's internet gateway allows it to connect anywhere on the internet to TCP ports 80, 443, and 8090 only. Connecting to an internet bastion box on one of these ports works and I can send and receive clear text data using netcat. I plan to use good old SSH, listening on tcp/8090 on the bastion, with a reverse port forward configured to expose sshd on the VM to the public, to show their Citrix gateway can be circumvented.

Rejected by Deep Packet Inspection

I hit an immediate snag. The moment I try to establish an SSH or SSL connection over o

It "types" the contents of the clipboard.

Why can't you just paste the contents you ask? Sometimes pasting just doesn't work.

One example is in system password fields on OSX.
Sometimes you're working in a VM and the clipboard isn't shared.
Other times you're working via Remote Desktop and again, the clipboard doesn't work in password boxes such as the system login prompts.
Connected via RDP and clipboard sharing is disabled and so is mounting of local drives. If the system doesn't have internet access there's no easy way to get things like payloads or Powershell scripts onto it... until now.

Windows

The Windows version is written in AutoHotKey and easily compiles to an executable. It's a single line script that maps Ctrl-Shift-V to type the clipboard.
