例 1:
index . js
// Node.js program to demonstrate the
// new X509Certificate(buffer) constructor function
// Importing crypto module
const {X509Certificate} = 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 subject included in this certificate.
// by using x509.subject function
const value = x509.subject
// display the result
console.log("subject :- " + value)
使用以下命令运行 index.js 文件:
node index.js
输出:
subject :- C=IN
ST=Westbengal
L=Kolkata
O=Panco, Inc.
CN=Rohit Prasad

// display the result
console.log((new X509Certificate(
