Install the Cloudflare root certificate

Advanced security features including HTTPS traffic inspection require users to install and trust the Cloudflare root certificate on their machine or device. If you are installing certificates manually on all of your devices, these steps will need to be performed on each new device that is to be subject to HTTP filtering.

​Download the Cloudflare root certificate

First, download the Cloudflare certificate from this location.

​Verify the certificate fingerprint

To verify your download, check that the certificate's thumbprint matches:

​SHA1

BB:2D:B6:3D:6B:DE:DA:06:4E:CA:CB:40:F6:F2:61:40:B7:10:F0:6C

​SHA256

F5:E1:56:C4:89:78:77:AD:79:3A:1E:83:FA:77:83:F1:9C:B0:C6:1B:58:2C:2F:50:11:B3:37:72:7C:62:3D:EF

​Add the certificate to your system

​MacOS

On MacOS, you can choose to install the Cloudflare root certificate with three different methods:

• Keychain
• Base Operating System
• Python

​Keychain

You will need to install the root certificate in the Keychain Access application. In the application, you can choose the keychain in which you want to install the certificate. macOS offers three options, each having a different impact on which users will be affected by trusting the root certificate.

Installing the certificate in the Login keychain will result in only the logged in user trusting the Cloudflare certificate. Installing it in the System keychain affects all users who have access to that machine.

To install the certificate in Keychain Access:

1. Download the Cloudflare certificate here.

2. Double-click on the .crt file.

3. In the pop-up message, choose the option that suits your needs (login, Local Items, or System) and click Add.

   

   The certificate is now listed in your preferred keychain within the Keychain Access application. You can always move the certificate under a different keychain by dragging and dropping the certificate onto the desired keychain on the left.

   

4. Double-click on the certificate.

5. Click Trust.

6. From the When using this certificate drop-down menu, select Always Trust.

7. Close the menu.

The root certificate is now installed and ready to be used.

​Base Operating System

You can install the Cloudflare certificate on your terminal, too.

1. Download the Cloudflare certificate here.

2. Open Terminal.

3. Launch the following command:

   sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain <Cloudflare_CA.crt>

4. Update the OpenSSL CA Store to include the Cloudflare certificate:

   sudo cat Cloudflare_CA.crt >> /usr/local/etc/openssl/cert.pem

​Python on Mac

1. Download the Cloudflare certificate here.

2. Install the certifi package.

   pip install certifi

3. Identify the CA store by running:

   python -m certifi

4. This will output:

   ~/Library/Python/3.7/lib/python/site-packages/certifi/cert.pem

5. Append the Cloudflare certificate to this CA Store by running:

   cat Cloudflare_CA.crt >> $(python -m certifi)

6. If needed, configure system variables to point to this CA Store by running:

   export CERT_PATH=$(python -m certifi)export SSL_CERT_FILE=${CERT_PATH}export REQUESTS_CA_BUNDLE=${CERT_PATH}

​iOS

1. Download the Cloudflare certificate here.

   The device will show a message: This website is trying to open Settings to how you a configuration profile. Do you want to allow this?

   The certificate is now installed. However, before it can be used, it must be trusted by the device.
