Introduction to Keybox XML: Creating a New Keybox

Keybox XML is a configuration file used by the Keybox application, which provides a simple and secure way to manage SSH connections. When setting up a new Keybox configuration, creating a new keybox XML file is the first step. This guide will walk you through the process of creating a new keybox XML file using the keyboxxml new command.

3.4. API Changes (Example – Python binding)

# Old (v1)
keybox = KeyboxXML.load("keys.xml")
key = keybox.get_key("api-key-1")  # returns raw bytes

Option A: Using the Official Keybox Tool (Linux/macOS/Windows)


Google’s keybox_generator binary (available to authorized OEMs) can now output the new format:


keybox_generator --output-format=xml:v2 \
  --algorithm=ec \
  --curve=p256 \
  --attestation-metadata=latest \
  --output=new_keybox.xml



The --output-format=xml:v2 flag ensures the new structure.


2. Background


KeyboxXML is a middleware component designed to store, retrieve, and validate cryptographic keys (symmetric, asymmetric) and X.509 certificates within structured XML containers. Previous versions (v1.x) faced limitations in: keyboxxml new


    

  • Parsing speed for large keybags.
    • 

  • Support for modern algorithms (e.g., ChaCha20, Ed25519).
    • 

  • Schema rigidity when integrating with external identity providers.
    • 



The "new" designation marks a major version release aimed at addressing these gaps.

Just audited the new KeyboxXML schema. 🔐


Big changes:
• TEE-only keys are now strictly separated from StrongBox.
• Revocation lists are parsing faster (no more latency hell).
• If your root_of_trust is malformed, you're instantly blocked.


Time to refresh your keyboxes. The old tricks won't work. 📉 The  --output-format=xml:v2  flag ensures the new structure

Prerequisites:


    

  • Rooted Android device (or OEM signing keys).
    • 

  • Access to /data/vendor/widevine/ or /mnt/vendor/persist/.
    • 



3. Support for Multiple Key Algorithms


Old keyboxes were often RSA-only. The new standard natively supports:


    

  • RSA (2048, 3072, 4096)
    • 

  • ECC (NIST P-256, P-384)
    • 

  • AES (for symmetric attestation, rarely used)
    •
