How Does DigiCert KeyLocker Work?

Before utilizing any of the solutions, it’s always recommended to understand its workflow. DigiCert KeyLocker works in a quite streamlined manner, combining the tasks that need to be completed by the user and the solution itself.

Its workflow executes per the following steps:

Step 1: Create an account on the DigiCert CertCentral platform.

Step 2: Contact a DigiCert representative through support or customer care, asking them to enable the KeyLocker facility on your CertCentral account.

Step 3: Use the CertCentral account to order a Code Signing Certificate. It’s recommended to use an OV and EV certificate for robust security and to sign any type of executable file.

Step 4: While ordering the certificate, select the provisioning method as DigiCert KeyLocker.

Step 5: DigiCert CertCentral will request to create a DigiCert ONE account for the approver. At this stage, the KeyLocker lead, who will have privileges equal to an admin, will be selected.

Following are the two cases used to select the KeyLocker lead.

• If the approved permissions are provided to the requester, then the requester is the KeyLocker lead.
• If the requester doesn’t have approved permission, then the certificate approver is the KeyLocker lead.

Step 6: After the KeyLocker lead selection, the organization’s CertCentral approver will receive emails about DigiCert ONE account creation and resetting the account’s password.

Step 7: The DigiCert KeyLocker will now create and store the private key on a cloud-based hardware security module.

Step 8: The KeyLocker will generate a code signing request (CSR) using the private key.

Step 9: The CSR will be uploaded to the CertCentral platform by the KeyLocker.

Step 10: The CA will assess the company information and issue you a code signing certificate as requested.

Step 11: The selected KeyLocker lead will sign into the DigiCert ONE account and invite additional users.

Step 12: The added users can now access the certificate and sign the supported executable files. Also, the KeyLocker lead can remove and add new users and modify their permissions on the platform.

Exclusive Benefits of DigiCert KeyLocker

If you choose DigiCert KeyLocker for generating and storing your code signing certificate private key, you can avail of the following listed benefits.

24/7 Availability

Regardless of the time and your physical location, you will be capable of signing software and releasing it for end-users. In addition, it will also help you select who can access the private key by configuring the roles and responsibilities per security and business architecture.

Compliance To Necessary Standards

Currently, the CA/B enables storage of private keys in a FIPS 140-2 Level 3 HSM. Any other HSM is not recommended, and its usage is prohibited due to weak security. But, by using DigiCert KeyLocker, you can be assured of aligning with the latest standards all the time. DigiCert itself is a certificate authority and updates its overall systems as soon as a new policy/protocol/standard is defined.

Authentication and Authorization

The DigiCert KeyLocker platform enables you to add the user per your needs and configure the policies accordingly. As a KeyLocker lead, you can remove and add new user regardless of the time and even restrict their usage. Further, it allows to configure multi-factor authentication to enable only authorized signing activities.

Reduces Key Management Efforts

With KeyLocker, you are not required to manage a physical HSM device. All the private keys and certificates will be stored on a cloud-based solution. You are only required to log into your CertCentral account, and access will be provided. It will reduce the effort of handling the physical device and use additional security controls, such as biometrics or metal safes, to prevent unauthorized access.

Affordable

By using the KeyLocker solution, you can save money used for purchasing a physical hardware token and installation of security mechanisms. In addition, it will be affordable in the long run, as DigiCert will automatically update its system to comply with new standards. Therefore, not now or in the future, you will be required to buy an HSM device.

Executes All Significant Operations

The KeyLocker fulfills all the requirements and functionalities of a physical hardware security module. The HSM functionality is provided to you through a logical interface, but at the backend, a hardware device stores your private key. You can generate CSR, submit it to CA, receive the issued certificate, and sign the executable using this DigiCert solution.

CI/CD Integration

Nowadays, the DevOps development lifecycle is highly used by development teams. Most of this process is automated, and with KeyLocker, you can also integrate and automate software signing. All the signing processes will be completed in a secure environment, and you will receive a ready-to-release executable file.
