原文:https://www . geesforgeks . org/node-js-x509-checkprivate key-function/
x509.checkPrivateKey() 是加密模块中 x509 证书类的内置应用程序编程接口，用于检查该证书的公钥是否与给定的私钥一致。
语法:
const x509.checkPrivateKey(privateKey)
参数:该函数以私钥对象为参数。
返回值:当且仅当该证书的公钥与给定的私钥一致时，该函数返回布尔值 true。
如何生成公共证书？
公共证书:打开记事本复制粘贴以下密钥，将文件保存为 公共证书 pem

例 1:
index . js
// Node.js program to demonstrate the
// x509.checkPrivateKey() function
// Importing crypto module
const {X509Certificate,createPrivateKey} = require('crypto')
// Importing fs module
const fs = require('fs')
// getting object of a PEM encoded X509 Certificate.
const x509 = new X509Certificate
(fs.readFileSync('public-cert.pem'));
// getting private key object
const key = createPrivateKey
(fs.readFileSync('private-key.pem'))
// checking if the public key is consistent or not
// by using x509.checkPrivateKey() function
const value = x509.checkPrivateKey(key)
// display the result
if(value)
console.log("public key is consistant")
else
console.log("public key is not consitant")
使用以下命令运行 index.js 文件:
node index.js
输出:
public key is consistant
例 2:

if((new X509Certificate(fs.readFileSync('public-cert.pem')))
.checkPrivateKey(createPrivateKey(fs.readFileSync('private-key.pem'))))
console.log("public key is consistant")
else
console.log("public key is not consitant")
使用以下命令运行 index.js 文件:
node index.js
输出:
public key is consistant
