VitaSSH – SSH Client for PS Vita by Rompelhd

VitaSSH is a proof-of-concept SSH client designed specifically for the PlayStation Vita, leveraging libssh2 for secure shell connections and VitaSDK for native Vita hardware integration. This experimental client provides basic SSH terminal functionality on the Vita's unique platform.

🛠 Technical Foundation

Built with:

Libssh2: Comprehensive SSH2 protocol implementation.
Vita2d: Vita2d library for creating 2D graphics.
VitaSDK: Official PlayStation Vita homebrew SDK.
IME Dialog System: Vita's on-screen keyboard interface.

⚡ Features and Limitations

✅ Working Features

Secure SSH2 connections with password authentication.
Arbitrary command execution on remote systems.
Special character filtering for Vita display compatibility.
Network state monitoring with visual feedback.
Memory-safe resource cleanup.

⚠️ Current Limitations

No scrollback: Screen clears after each command.
No command history: Manual retyping required.
No touch input: Physical buttons only (TRIANGLE/SQUARE).
Limited character set: ASCII-only display output.
No interactive sessions: Single commands only.
Experimental status: Not for production use.

🔄 Technical Challenges Solved

Vita IME Integration: Bridging UTF-16 keyboard to ASCII SSH.
Graphics Context Switching: Seamless GXM ↔ debugScreen transitions.
Memory Management: CDRAM/User RAM allocation strategies.
Network Reliability: Vita-specific NetCtl state handling.
Output Sanitization: ANSI/Unicode filtering for text display.

🚀 Build & Deployment

# VitaSDK environment required
mkdir build && cd build
cmake ..
make

📦 Generates

ssh_client_vita.self (Vita executable)
ssh_client_vita.vpk (Installation package)

🎯 Use Cases

Remote server administration from the PS Vita
Quick file system inspection using ls, df, etc.
Network troubleshooting with ping, netstat
Educational demonstration of Vita homebrew capabilities
SSH protocol testing in constrained environments

📋 Prerequisites

PlayStation Vita with homebrew enabled
VitaSDK development environment
libssh2 library compiled for Vita
OpenSSL libraries for Vita

🔧 Installation

Copy the generated .vpk file to your Vita.
Install it using VitaShell or the Package Manager.
Make sure you have network connectivity (WiFi required).
Launch VitaSSH and configure your connection details.

🎮 Controls

TRIANGLE: Open on-screen keyboard for commands
SQUARE: Exit the application
D-Pad/Stick: Navigate through IME dialogs
X Button: Confirm/enter in dialogs

⚠️ Important Notes

This is experimental software — use at your own risk.
Some SSH servers may require specific configuration.
Complex commands with extensive output may cause display issues.
Password authentication only (no key-based authentication yet).

🐛 Known Issues

Limited output buffer for long command responses
No support for interactive programs (vim, top, etc.)
~~Character encoding limitations for non-ASCII text~~ ✅
Occasional timeouts on unstable network connections
