crypto.diffieHellman(options[, callback])


基于 privateKeypublicKey 计算 Diffie-Hellman 秘密。两个密钥必须具有相同的 asymmetricKeyType,该 asymmetricKeyType 必须是 'dh'(用于 Diffie-Hellman)、'ec''x448''x25519'(用于 ECDH)之一。

¥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', 'x448', or 'x25519' (for ECDH).

如果提供了 callback 函数,则该函数使用 libuv 的线程池。

¥If the callback function is provided this function uses libuv's threadpool.
