PS4 Auth Upload

Joypad OS — Install local RSA authentication key material

What this does: Stores your DS4 authentication key material directly in the device's flash. Once uploaded, Joypad OS can authenticate with a PS4 console without a real DS4 dongle connected.

Files needed:
• key.prm — RSA-2048 private key (PEM format)
• serial.txt — 32 hex characters (device serial)
• sig.bin — 256 bytes (Sony-issued device signature)

Browser requirement: Chrome or Edge (Web Serial API). Connect your device via USB then click Connect.
