crypto.setEngine(engine[, flags])

• engine <string>
• flags <crypto.constants> 默认值: crypto.constants.ENGINE_METHOD_ALL

为部分或所有 OpenSSL 功能（由标志选择）加载并设置 engine。

engine 可以是 id 或引擎共享库的路径。

可选的 flags 参数默认使用 ENGINE_METHOD_ALL。 flags 是采用以下标志之一或混合的位字段（在 crypto.constants 中定义）：

• 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

以下标志在 OpenSSL-1.1.0 中已弃用。

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

• 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
