• engine {string}
    • flags {crypto.constants} Default: crypto.constants.ENGINE_METHOD_ALL

    Load and set the engine for some or all OpenSSL functions (selected by flags).

    engine could be either an id or a path to the engine’s shared library.

    The optional flags argument uses ENGINE_METHOD_ALL by default. The flags is a bit field taking one of or a mix of the following flags (defined in crypto.constants):

    • crypto.constants.ENGINE_METHOD_RSA
    • crypto.constants.ENGINE_METHOD_DSA
    • crypto.constants.ENGINE_METHOD_DH
    • crypto.constants.ENGINE_METHOD_RAND
    • crypto.constants.ENGINE_METHOD_EC
    • crypto.constants.ENGINE_METHOD_CIPHERS
    • crypto.constants.ENGINE_METHOD_DIGESTS
    • crypto.constants.ENGINE_METHOD_PKEY_METHS
    • crypto.constants.ENGINE_METHOD_PKEY_ASN1_METHS
    • crypto.constants.ENGINE_METHOD_ALL
    • crypto.constants.ENGINE_METHOD_NONE

    The flags below are deprecated in OpenSSL-1.1.0.

    • crypto.constants.ENGINE_METHOD_ECDH
    • crypto.constants.ENGINE_METHOD_ECDSA
    • crypto.constants.ENGINE_METHOD_STORE
