AirGap VaultHandles The Private Key

The AirGap Vault app is installed on a dedicated or old smartphone that has no connection to any network, thus it is air gapped.

The most secure private key generation in the industry

The enhanced entropy concept adds video, audio, accelerator 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.

Secure Storage

Dedicated secure storage, the private key is saved in the secure enclave of the mobile device and needs multi-step biometric authentication every time it is accessed.

Social Recovery

Secure key handling with social recovery option, for example, split a private key into 4 shares, but only 3 shares are needed for a full recovery of the key. Based on Shamir‘s Secret Sharing Standard.

Event Detection

Continuous checks for network connectivity, root access and screenshot detection in order to avoid the device being compromised.
