## Rotating login.gov credentials
The DJANGO_SECRET_KEY and DJANGO_SECRET_LOGIN_KEY are reset once a year for each sandbox, see their sections below for more information on them and how to manually generate these keys. To save time, complete the following steps to rotate these credentials using a script in non-production environments:

### Step 1 login

To run the script make sure you are logged on the cf cli and make sure you have access to the [Login Partner Dashboard](https://dashboard.int.identitysandbox.gov/service_providers/2640).

### Step 2 Run the script

Run the following where "ENV" refers to whichever sandbox you want to reset credentials on. Note, the below assumes you are in the root directory of our app.

```bash
ops/scripts/rotate_login_certs.sh ENV
```

### Step 3 Respond to the terminal prompts

Respond to the prompts from the script and, when it asks for the cert information, the below is an example of what you should enter. Note for "Common Name" you should put the name of the sandbox and for "Email Address" it should be the address of who owns that sandbox (such as the developer's email, if it's a develop sandbox, or whoever ran this action otherwise)

```bash
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:DC
Locality Name (eg, city) []:DC
Organization Name (eg, company) [Internet Widgits Pty Ltd]:DHS
Organizational Unit Name (eg, section) []:CISA
Common Name (e.g. server FQDN or YOUR name) []:ENV
Email Address []: [email protected]
```

Note when this script is done it will have generated a .pem and a .crt file, as well as updated the cert info on the sandbox

### Step 4 Delete the old cert

Navigate to to the Login Partner Dashboard linked above and delete the old cert

### Step 5 add the new cert

In whichever directory you ran the script there should now be a .crt file named "public-ENV.crt", where ENV is the space name you used on Step 2. Upload this cert in the Login Partner Dashboard in the same section where you deleted the old one.

### Production only

This script should not be run in production. Instead, you will need to manually create the keys and then refrain from updating the sandbox. Once the cert is created you will upload it to the Login Partner Dashboard for our production system, and then open a ticket with them to update our existing Login.gov integration. Once they respond back saying it has been applied, you can then update the sandbox.

You'll need to give the new certificate to the registry vendor _before_ rotating it in production. Once it has been accepted by the vendor, make sure to update the kdbx file on Google Drive.
