register
Registers a new device by generating biometric-only protected RSA key pairs.
This method creates a new RSA key pair in the Android Keystore with exclusive biometric protection, ensuring that keys can only be accessed through biometric authentication without any fallback mechanisms. The key generation process adapts to device capabilities while maintaining strict biometric-only access requirements.
Return
Result containing KeyPair with public key, private key reference, and key alias on success, or failure with appropriate exception
Parameters
Android context for accessing system services and checking device capabilities
Attestation configuration specifying hardware verification requirements. Attestation.Default enables hardware attestation with challenge verification. Attestation.None generates keys without attestation.
