nodejs-self-signed-certificate-example
|
||||
======================================
|
||||
|
||||
The end off all your self-sign certificate woes (in node.js at least)
|
||||
An example that works.
|
||||
|
||||
The end off all your self-signed certificate woes (in node.js at least)
|
||||
|
||||
Test for yourself
|
||||
---
|
||||
|
||||
This is an easy-as-git-clone example that will get you on your way without
|
||||
any `DEPTH_ZERO_SELF_SIGNED_CERT` or `SSL certificate problem: Invalid certificate chain` headaches.
|
||||
|
||||
### Get the repo
|
||||
|
||||
```bash
|
||||
git clone git@github.com:coolaj86/nodejs-self-signed-certificate-example.git
|
||||
pushd nodejs-self-signed-certificate-example
|
||||
npm install
|
||||
```
|
||||
|
||||
**For the super impatient**:
|
||||
|
||||
```bash
|
||||
bash test.sh
|
||||
```
|
||||
|
||||
### Create certificates for `local.ldsconnect.org`
|
||||
|
||||
`local.ldsconnect.org` points to `localhost`, so it's ideal for your first test.
|
||||
|
||||
```bash
|
||||
bash make-root-ca-and-certificates.sh 'local.ldsconnect.org'
|
||||
```
|
||||
|
||||
### Run the server
|
||||
|
||||
```bash
|
||||
node ./serve.js 4443 &
|
||||
# use `fg` and `ctrl+c` to kill
|
||||
```
|
||||
|
||||
|
||||
### Test in a client
|
||||
|
||||
Visit in a web browser
|
||||
|
||||
<https://local.ldsconnect.org>
|
||||
|
||||
Test (warning free) in node.js
|
||||
|
||||
```bash
|
||||
node ./request-without-warnings.js 4443
|
||||
```
|
||||
|
||||
Test (warning free) with cURL
|
||||
|
||||
```bash
|
||||
curl -v https://local.ldsconnect.org \
|
||||
--cacert client/my-private-root-ca.crt.pem
|
||||
```
|
||||
|
||||
Now season to taste
|
||||
---
|
||||
|
||||
You can poke around in the files for generating the certificates,
|
||||
but all you really have to do is replace `local.ldsconnect.org`
|
||||
with your very own domain name.
|
||||
|
||||
But where's the magic?
|
||||
====
|
||||
|
||||
Who's the man behind the curtain you ask?
|
||||
|
||||
Well... I lied. This demo doesn't use self-signed certificates.
|
||||
It uses a self-signed Root CA and a signed certificate.
|
||||
|
||||
It turns out that self-signed certificates were designed to be
|
||||
used by the Root Certificate Authorities, not by web servers.
|
||||
|
||||
So instead of trying to work through eleventeen brazillion errors
|
||||
about self-signed certs, you can just create an authority and then
|
||||
add the authority to your chain (viola, now it's trusted).
