node.js - 如何检查/获取 ssl 证书到期日期

Question

我有 Let's encrypt 证书包。它包括私钥和certificate.crt

使用 node.js 和 node-forge(不是 openssl)，如何获取 certificate.crt 的到期日期？

Answer 1

你可以使用x509模块

var crt_pem = "<certificate in pem format which is content of your certificate.crt>";
const x509 = require('x509');
var crt_obj = x509.parseCert(crt_pem);
console.log(crt_obj.notBefore);
console.log(crt_obj.notAfter);
