/**
 * Parses a transport extension from an attestation certificate and returns
 * a List of HardwareFeatures supported by the security key. The specification of
 * the HardwareFeatures in the certificate should match their internal definition in
 * device_auth.proto//  w  ww .ja v  a2s . c om
 *
 * <p>The expected transport extension value is a BIT STRING containing the enabled
 * transports:
 *
 *  <p>FIDOU2FTransports ::= BIT STRING {
 *       bluetoothRadio(0), -- Bluetooth Classic
 *       bluetoothLowEnergyRadio(1),
 *       uSB(2),
 *       nFC(3)
 *     }
 *
 *   <p>Note that the BIT STRING must be wrapped in an OCTET STRING.
 *   An extension that encodes BT, BLE, and NFC then looks as follows:
 *
 *   <p>SEQUENCE (2 elem)
 *      OBJECT IDENTIFIER 1.3.6.1.4.1.45724.2.1.1
 *      OCTET STRING (1 elem)
 *        BIT STRING (4 bits) 1101
 *
 * @param cert the certificate to parse for extension
 * @return the supported transports as a List of HardwareFeatures or null if no extension
 * was found
