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.daplie.com",
|
|
"altnames": [
|
|
"localhost.daplie.com"
|
|
],
|
|
"issuedAt": 1465516800000,
|
|
"expiresAt": 1499731199000
|
|
}
|
|
```
|

With a few small changes this could also work in the browser (that's how its dependencies are designed).
