Configuring the connector

This page describes how to configure the connector to automate certificate lifecycle management.

Validate the domains

Log in to SCM at https://cert-manager.com/customer/<customer_uri> with the MRAO administrator credentials provided to your organization.

Sectigo runs multiple instances of SCM. The main instance of SCM is accessible at https://cert-manager.com. If your account is on a different instance, adjust the URL accordingly.
(Optional) Navigate to the Organizations page to see if an organization with departments already exists. On this page you can create a new organization or add departments to an existing organization.

To add an organization:
1. Click Add.
2. Complete the fields with the organization’s details, then click Next.
3. Configure settings for specific types of certificates.
4. Click Save.
5. Select the newly created organization from the list of organizations.
6. Click Add Department and complete the fields with the department’s details.
7. Click Validate to start the validation process for this organization.
Navigate to the Domains page.
To create a new domain entry, click Add.
Specify the domain name, select the organizations/departments to delegate the domain to, and the allowed certificate types.
Click Save.
If your organization or department requires delegations to be approved:
1. Select the newly created domain from the list of domains.
2. Click Approve Delegations.
3. Select the organization or department, then click Approve.
  
  To change the organization or department which the domain is delegated to, click Delegate and select the appropriate Organizations/Departments.
(Public CA only) Validate your domain:
1. Select your domain and click Validate.
2. Select the appropriate DCV method as per your initial setup.
  
  The following steps assume that you selected Email as the DCV method.
3. Click Next.
4. In Select an email address, select a registered email.
5. Click Submit.
  
  A message confirms that the validation letter was sent to your selected email.
6. Click OK.
7. Follow the instructions provided in the email to validate your domain.
  
  Once the domain is validated, its Status will change to Validated on the Domains page.

Obtain the SCM API credentials

Log in to SCM at https://cert-manager.com/customer/<customer_uri> with the MRAO administrator credentials provided to your organization.

Sectigo runs multiple instances of SCM. The main instance of SCM is accessible at https://cert-manager.com. If your account is on a different instance, adjust the URL accordingly.
Select Enrollment REST. Make a note of the URL value under SSL Certificates REST API. You will need to assign it to the sectigo_scm_url parameter in the config.yaml file.
Select SSL Certificates REST API and click Accounts.
Select your account and click Edit.
Click Reset Secret and confirm resetting the client secret.
Make a note of the values under Client ID and Application (client) Secret. You will need to assign them to the sectigo_cm_user_id and sectigo_cm_user_secret parameters in the sectigo_credentials.yaml file.

Extract the contents

Log in to your Linux client machine as a user with administrator privileges.
Create a new directory called sectigo somewhere on your machine and place the integration package in the newly created directory. The following commands assume that the package is located in opt/sectigo.

Navigate to /opt/sectigo and execute the following commands (you don’t need to install the unzip utility if you already have it).

sudo apt-get update
sudo apt-update install unzip
unzip Sectigo_PaloAltofw_Agent_<version>.zip -d /opt/sectigo

sudo yum update
sudo yum install unzip
unzip Sectigo_PaloAltofw_Agent_<version>.zip -d /opt/sectigo

Install the dependencies

Navigate to the sectigo-paloaltofw-agent_<version>/paloaltofw directory.
Install the Python dependencies listed in the requirements.txt file.

We recommend that you install Python packages into a virtual environment.

sectigo_gnu_key

The GPG key for encrypting the credentials. This parameter has effect if sectigo_encrypt_credentials is set to True.

Encrypting the credentials file

The connector can work with plaintext or encrypted configuration files. If you prefer to store your SCM and Palo Alto credentials in an encrypted form, you need to install the GPG command-line tool and SOPS editor of encrypted files.

Encrypting the SCM secret and Palo Alto API key is an optional but recommended step to protect your credentials from unauthorized access.

Install GPG

Run the following commands to install GPG (GNU Privacy Guard). The last two commands let you generate some randomness required to generate a key.

To check whether GPG is installed on the system, run gpg --version.

sudo apt-get install gnupg
sudo apt-get install rng-tools
sudo sed -i -e 's|#HRNGDEVICE=/dev/hwrng|HRNGDEVICE=/dev/urandom|' /etc/default/rng-tools
sudo service rng-tools start
GPG_TTY=$(tty)
export GPG_TTY

sudo yum install gnupg
sudo yum install rng-tools
sudo sed -i -e 's|#HRNGDEVICE=/dev/hwrng|HRNGDEVICE=/dev/urandom|' /etc/default/rng-tools
sudo service rng-tools start
GPG_TTY=$(tty)
export GPG_TTY

Install SOPS

Install the SOPS editor for encrypting and decrypting the credentials.

To check whether SOPS is installed on the system using the sops --version command.

Encrypt the credentials file

Change the value of the sectigo_encrypt_credentials parameter in the config.yaml file to True.
Create a private key.
- Unattended key generation
- Attended key generation
gpg --batch --passphrase '' --quick-gen-key $(whoami) default default
The --quick-generate-key option requires you to specify the user ID field on the command line and optionally an algorithm, usage, and expire date. Default values are used for all other options.
gpg --full-generate-key
The --generate-key option prompts for the real name and email fields before asking for a confirmation to proceed, and provides a dialog for all options.
Retrieve the key fingerprint.
```
gpg -list-keys
```
Add the fingerprint to the sectigo_gnu_key parameter in config.yaml.

Encrypt the credentials.

All certificate profiles
Specific certificate profile

python3 paloaltoagent.py -a encrypt -p <certificate>.yaml

python3 paloaltoagent.py -a encrypt -p <certificate>.yaml

Edit the credentials file

If you need to edit the ecrypted file, first decrypt it.

python3 paloaltoagent.py -a decrypt -p <certificate>.yaml
