crypto.createPrivateKey(key)

• key <Object> | <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView>

  • key：<string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <Object> 密钥材料，采用 PEM、DER 或 JWK 格式。

    ¥key: <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <Object> The key material, either in PEM, DER, or JWK format.

  • format：<string> 必须是 'pem'、'der' 或“'jwk'”。默认值：'pem'。

    ¥format: <string> Must be 'pem', 'der', or ''jwk'. Default: 'pem'.

  • type：<string> 必须是 'pkcs1'、'pkcs8' 或 'sec1'。仅当 format 为 'der' 时才需要此选项，否则将被忽略。

    ¥type: <string> Must be 'pkcs1', 'pkcs8' or 'sec1'. This option is required only if the format is 'der' and ignored otherwise.

  • passphrase：<string> | <Buffer> 用于解密的密码。

    ¥passphrase: <string> | <Buffer> The passphrase to use for decryption.

  • encoding：<string> 当 key 是字符串时使用的字符串编码。

    ¥encoding: <string> The string encoding to use when key is a string.

• 返回：<KeyObject>

  ¥Returns: <KeyObject>

创建并返回包含私钥的新密钥对象。如果 key 是字符串或 Buffer，则假定 format 为 'pem'；否则，key 必须是具有上述属性的对象。

¥Creates and returns a new key object containing a private key. If key is a string or Buffer, format is assumed to be 'pem'; otherwise, key must be an object with the properties described above.

如果私钥被加密，则必须指定 passphrase。密码的长度限制为 1024 字节。

¥If the private key is encrypted, a passphrase must be specified. The length of the passphrase is limited to 1024 bytes.
