parse ssl certificate in javascript

To parse an SSL certificate in JavaScript, you can use the crypto module in Node.js. Here's an example code snippet that demonstrates how to parse an SSL certificate in JavaScript:

index.tsx
const { readFileSync } = require('fs');
const { Certificate } = require('crypto');

const certPath = 'path/to/cert.pem';

// Read the SSL certificate file
const cert = readFileSync(certPath);

// Parse the SSL certificate
const parsedCert = new Certificate(cert);

// Print the parsed certificate details
console.log(parsedCert.subject);
console.log(parsedCert.issuer);
console.log(parsedCert.notBefore);
console.log(parsedCert.notAfter);
console.log(parsedCert.fingerprint);

In this example, we're using the fs and crypto modules in Node.js to read the contents of an SSL certificate file and parse it using the Certificate class. The parsed certificate object provides access to a variety of certificate details, such as the subject and issuer names, the certificate validity dates, and the certificate fingerprint.
