# [certpem.js](https://git.coolaj86.com/coolaj86/cert-info.js)
|
|
|
|
Read basic info from a cert.pem / x509 certificate.
|
|
|
|
Used for [Greenlock.js](https://git.coolaj86.com/coolaj86/greenlock-express.js)
|
|
|
|
# Install
|
|
|
|
```bash
|
|
# bin
|
|
npm install --global certpem
|
|
|
|
# node.js library
|
|
npm install --save certpem
|
|
```
|
|
|
|
# Usage
|
|
|
|
## CLI
|
|
|
|
For basic info (subject, altnames, issuedAt, expiresAt):
|
|
|
|
```bash
|
|
certpem /path/to/cert.pem
|
|
```
|
|
|
|
Output all info by passing `--debug` or use `--json` to see the basic info pretty-printed.
|
|
|
|
## node.js
|
|
|
|
```javascript
|
|
'use strict';
|
|
|
|
var certpem = require('certpem').certpem
|
|
var cert = fs.readFile('cert.pem', 'ascii', function (err, certstr) {
|
|
|
|
// basic info
|
|
console.info(certpem.info(certstr));
|
|
|
|
// way too much info
|
|
// (requires npm install --save node.extend@1)
|
|
console.info(certpem.debug(certstr));
|
|
|
|
});
|
|
```
|
|
|
|
Example output:
|
|
|
|
```javascript
|
|
{
|
|
"subject": "localhost.example.com",
|
|
"altnames": [
|
|
"localhost.example.com"
|
|
],
|
|
"issuedAt": 1465516800000,
|
|
"expiresAt": 1499731199000
|
|
}
|
|
```
|
|
|
|
With a few small changes this could also work in the browser (that's how its dependencies are designed).
