php - 与nodejs相比，无法验证php中的openssl签名

Question

我可以使用 Nodejs 来验证签名，crypto.createVerify而 PHP：openssl_verify总是返回 false。

Nodejs：获得正确的结果

const encryptKey = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
const crypto = require('crypto');

var data = Buffer.from(JSON.stringify(vd), "utf-8");
var password = Buffer.from(encryptKey, "utf-8");
var hashPassword = crypto.createHash('sha256').update(password).digest();
