¬ Install AirGap Vault Distro
¬ CDROM:

Use your favorite program to burn the ISO to CDROM. Nothing special. CDROMs are naturally read-only and tamper resistant.

¬ USB:

If you don’t burn AirGap to a CDROM, writing AirGap Vault to a USB stick with a hardware read-write toggle (e.g., Kanguru FlashBlu) is the next best thing.

“Generate” a new secret, you can also import an existing mnemonic phrase. We recommend that you generate a new secret on the air-gapped device and not import one that was previously used in a device with network connectivity.

3 ¬ Generate your secret

The enhanced entropy concept adds video, audio and touch data to the entropy seed alongside the device’s pre-shipped secure random generator in order to generate a cryptographically secure seed used for the secret generation.

If an entropy source is not available, it won’t be included in the entropy collection process.
