ADB Key Management

ADB requires an RSA cryptographic keypair to authenticate connections with target Android devices. Dioxamine generates and manages its own internal ADB keypair securely within the app.

Accessing ADB Key Settings

Tap the Settings tab in the bottom navigation bar.
Tap on the ADB Key expandable card.

Key Management Options

1. Viewing Key Fingerprint

Dioxamine displays the SHA-256 fingerprint of your active public RSA key (e.g. SHA256:abcd1234...).
When connecting to a target device for the first time, this fingerprint matches the prompt shown on the target phone screen.

2. Regenerate Key Pair

Tap Regenerate Key to delete the current keypair and create a fresh 2048-bit RSA key.
When to use: If an unauthorized device has whitelisted your key, or if you wish to reset trust on all previously paired devices.
After regenerating, all target devices will prompt to re-authorize the connection when plugged in.

3. Load Custom Key (Import)

Tap Load Custom Key to import an existing adbkey private key file from your phone storage (for example, copied from your PC’s ~/.android/adbkey).
Why use this: Allows Dioxamine to connect to devices that already trust your PC without showing the authorization prompt again.

4. Export Key (Backup)

Tap Export Key to save your active private adbkey file to your phone’s storage.
Useful for creating backups or migrating your authorization key to another phone.
