crypto.diffieHellman(options)

• options：<Object>
  • privateKey：<KeyObject>
  • publicKey：<KeyObject>
• 返回值：<Buffer>

基于 privateKey 和 publicKey 计算 Diffie-Hellman 秘密。两个密钥必须具有相同的 asymmetricKeyType，且该类型必须是 'dh'（用于 Diffie-Hellman）、'ec'（用于 ECDH）、'x448' 或 'x25519'（用于 ECDH-ES）。

【Computes the Diffie-Hellman secret based on a privateKey and a publicKey. Both keys must have the same asymmetricKeyType, which must be one of 'dh' (for Diffie-Hellman), 'ec' (for ECDH), 'x448', or 'x25519' (for ECDH-ES).】
