 * OpenSSL Engine for Embedded Secure Element (A70CM)
 *
 * This engine invokes the API of axHostSw/a70cm that wraps APDU communication
 * with the A70CM secure element.
 *
 * The following operations are supported by this engine:
 * - Random number generation
 * - RSA signature generation
 * - RSA Encryption
 * - RSA Decryption
 * - RSA signature verification
 * - ECC sign
 * - ECC verify : reroute calls to openssl sw API when valid key is not detected
 * - ECDH compute_key (shared secret generation)
 * ----------------------------------------------------------------------------*/
