How to change your Jiango Secrets key (without breaking your app)

If you are working on a Jiango Project, you will probably come with it SECRET_KEY Your settings in the file. It looks like just another line of code, but it is one of the most important pieces of your project.

SECRET_KEY Saves your app by signing cookies, passwords and other sensitive data. And if it is ever exposed or leaked – yes, it’s a problem.

Changing your Jiango SECRET_KEY Should you carefully do it? Your key may have been determined to the gut hub (we are all there), or you want to refresh it for better security.

Whatever the reason, I will walk on a way to do it safely without breaking you anything. I will explain everything in simple English so that you do not survive what happened right now.

Let’s enter it.

What is Jiango? SECRET_KEY?

SECRET_KEY You have a long string of random characters stored in settings.py File This is used internally by Jiango:

• Sign Safety Session Cookies

• Refrigerate Passwords Prepare tokens

• Protect data using Cryptographic Signing

How does it look like in your Jingo Project:

SECRET_KEY = 'django-insecure-12345supersecretrandomstring'

If someone has access to you SECRET_KEYThey likely:

• Forge session cookies and imitation users

• Refrigerate Passwords with signed data

• Compromise on the entire app

So yes – this is a big deal.

When should you change your Jiango Secret key?

You should change your SECRET_KEY If:

• You mistakenly shared it in a public code (such as Gut Hub)

• This was a tough code in a file, and you want to go to environmental variables

• You are rotating the keys as part of the security policy

• You suspect that it has been compromised

Still not sure it is necessary? If the key has ever been shared or stored where anyone else can access it, change it.

How to change your Jingo SECRET_KEY Safely

1. Prepare a new secret key

The key needs to be long, random and safe. Jiango does not provide a command for it outside the box, but you can produce one using azar.

Here is a simple script:

from django.core.management.utils import get_random_secret_key

print(get_random_secret_key())

To drive this:

1. Open your terminal

2. Run with Jiango Shell python manage.py shell

3. Stick to the script

It will return something like this:

x3%6kn$mlg58+as!rcvnmvd8%(2p!p

Copy this. You will need it in a second.

2. Store the key safely (don’t do this hard code)

Instead of sticking into it settings.pyIt is better to use environmental variables. That way, if you ever share your code, you are not in danger of exposing it.

How’s it:

1. Open your own .env File (make one if it doesn’t exist):

SECRET_KEY='x3%6kn$mlg58+as!rcvnmvd8%(2p!p#&yk@r)+tdlj*w9kx!5gx'

2. Install python-decouple If you don’t have before:

pip install python-decouple

3. Do your update settings.py:

from decouple import config

SECRET_KEY = config('SECRET_KEY')

Now your key is safe out of your code. More secure

3. Carefully commit

Make sure:

How is here? .gitignore Should see:

.env

You will be surprised how often .env The files are pushed by accident. Always check double before committing.

4. Re -start your app

After changing the key, restart your server. If you are using a platform like Heroco or Doker, make sure you update it SECRET_KEY Different dashboard in your environment.

For Heroko:

heroku config:set SECRET_KEY='your-new-key'

For the Doker:

environment:
  - SECRET_KEY=your-new-key

5. Log in again (and users somewhere to do so)

Changing the secret key invalidates all old sessions. Therefore, everyone (including you) will be logged out. This is expected. If you are running a public site, it is a good idea to inform users in advance.

What happens if you don’t change it?

If your key has been compromised, may attack:

This is not just about the best ways. It’s about the safety of the real world.

Normal questionnaire

Will it break my app?

No, as long as you restart your app and store the key properly, everything will work well. Just remember: All users will log out.

Can I use the same key for multiple projects?

No. Each project should have its unique secret key.

Can I rotate the key regularly?

Yes, keep in mind that changing it often makes users logging in repeatedly.

I forgot to add .env to .gitignore. What now?

Create the key, update your project, and make sure the new .env The file is not track.

The final views

Changing your Jiango SECRET_KEY For the first time there may be a feeling of scary, but it is very easy when you break it. As long as you create a safe key, store it safely, and don’t expose it publicly, you are doing great.

One last thing –When was the last time you checked that your secret key was mistakenly pushed to the gut hub? This can be a good time to take a sharp look.
