Scripts for signing using KSP library on GitLab

Prerequisites

A GitLab repository
DigiCert® KeyLocker credentials
DigiCert® KeyLocker client tools

Client tools

DigiCert® KeyLocker clients can be downloaded in a package.

Download Client tools

Sign in to DigiCert ONE.
Navigate to DigiCert® KeyLocker > Resources > Client tool repository.
Select your operating system.
Click the download icon next to DigiCert® KeyLocker clients.

Register the KSP

To register the KSP, open a command prompt and run:

smksp_registrar.exe register

Verify the KSP

To verify that your KSP is configured properly, and that your client can properly authenticate to the DigiCert® KeyLocker service, run:

certutil.exe -csp "DigiCert Software Trust Manager KSP" -key -user

Synchronize certificates

For the client tools to access the private keys in the service through the Key Storage Provider (KSP), your certificates must be synchronized to the local certificate store. Only if the certificate is synchronized, the private key remains stored securely in DigiCert® KeyLocker.

To synchronize your certificates to the local certificate store, open a command prompt and run:

smksp_cert_sync.exe

To view the certificates, open Certificate Manager for the user account used to run the certificate sync utility:

certmgr.msc

If you do not see your certificates in the Certificate Manager, verify that you have opened the correct certificate store. There is a different certificate store for each Windows user account.

참고

All certificates are synched to the user store only. The certificates are not synchronized to the machine store (yet).

Set PATH environment variables

Operating systems use the environment variable called PATH to determine where executable files are stored on your system. Use the PATH environment variable to store the file path to your signing tools to ensure that the CLI can reference these signing tools.

예 1. Windows

You can set the PATH environment variable using command line or via the environment variables.

To set the path to your signing tools via command line:

set PATH=%path%;<path to DigiCert Keylocker Tools>

Command sample:

set PATH=%path%;C:\Program Files\DigiCert\DigiCert Keylocker Tools

To set the path to your signing tools for your system or account:

Search for environment variables in the Windows start menu.
Select Edit environment variables for your account or Edit system environment variables.
Double click on the Path variable.
Click New.
Select Browse.
Select the path to the signing tool.
Click OK to save the path.
Click on OK to close the dialog.

예 2. Linux

To set the path to your signing tools via command line:

Launch the Terminal application.
Open the file in an editor:
```
nano ~/.profile
```

Add any exports definitions you need:

export PATH=<Path to DigiCert Keylocker Tools>

Click CTRL+X to exit.
Click Y to save.
Click Enter to keep the same file name.
Execute the new .profile by restarting Terminal or using:
```
 source ~/.profile
```

예 3. macOS

To set the path to your signing tools via command line:

Launch the Terminal application.
Create a profile file:
```
touch ~/.zprofile
```
Open the file in an editor:
```
open ~/.zprofile
```

Add any exports definitions you need, such as:

export PATH=<Path to DigiCert Keylocker Tools>

To save the new .zprofile, click File > Save (CMD + S).
Close the terminal window and reopen to use new saved variables.

User authentication

DigiCert® KeyLocker enforces multifactor authentication for security. To access keypairs, certificates, and sign code, you need to set up two types of credentials: an API token and an authentication certificate.

Create an API token

The API token is an authentication method used to verify you as a user and your permissions assigned in DigiCert ONE. The API token provides the first factor authentication.

Follow these steps to generate an API token:

Sign in to DigiCert ONE.
Select the profile icon (top-right).
Select Admin Profile.
Scroll down to API Tokens.
Select  Create API token.
참고
The API token is only shown once, securely store the API key to use it later.

Create an authentication certificate

The client authentication certificate is an authentication method used to verify you as a user and your permissions assigned in DigiCert ONE. The client authentication certificate provides the second factor authentication.

Follow these steps to create a client authentication certificate:

Sign in to DigiCert ONE.
Select the profile icon (top-right).
Select Admin Profile.
Scroll down to Authentication certificates.
Select Create authentication certificate.
참고
The client authentication certificate password shown after creating an client authentication certificate cannot be accessed again, download the certificate and securely store the password to use it later.

DigiCert® KeyLocker environment variables

Set the following environment variables:

Variable	Description
SM_API_KEY	Provide your API token.
SM_CLIENT_CERT_FILE	Provide your client authentication certificate.
SM_CLIENT_CERT_PASSWORD	Provide your client certificate password.
SM_HOST	Provide your host environment.

Set certificate file in environment variables

Identify your client authentication certificate.
Encode the file to base64. For encoding run command:
```
base64 file_name
```

In GitLab > CI/CD Settings > Variables add the new variables:

Key = SM_CLIENT_CERT_FILE_B64
Value = encoded value from base64 file_name

Setup certificate file for signing:

stages:
  - set-SM-certificate

variables:
  SM_API_KEY: $SM_API_KEY
  SM_CLIENT_CERT_PASSWORD: $SM_CLIENT_CERT_PASSWORD
  SM_HOST: $SM_HOST

set_SM_certificate:
  stage: set-SM-certificate
  tags:  
  - shared-windows
  - windows
  - windows-1809

  script:
    - |
      cd C:\
      New-Item C:\CERT_FILE.p12.b64
      Set-Content -Path C:\CERT_FILE.p12.b64 -Value $SM_CLIENT_CERT_FILE_B64
      certutil -decode CERT_FILE.p12.b64 Certificate_pkcs12.p12

  variables:
    SM_CLIENT_CERT_FILE: 'C:\Certificate_pkcs12.p12'

Environment variables setup for GitLab CI/CD

The client tools need these environment variables to connect with DigiCert® KeyLocker.

They can be integrated as GitLab variables in GitLab Repository.

The values for these environment variables:

표 1. Environment variables

Environment variables	Description
SM_CLIENT_CERT_PASSWORD	The password from client authentication certificate setup.
SM_CLIENT_CERT_FILE_B64	The base64 encoded text of certificate downloaded from client authentication certificate setup.
SM_HOST	The path to the DigiCert ONE portal with client authorization. 참고 In most cases, this path stays as it is unless you are connecting to a self-hosted instance of the DigiCert ONE product.
SM_API_KEY	The API token generated during API token setup.
SM_CODE_SIGNING_CERT_SHA1_HASH	The certificate fingerprint.

Command to set environment variables:

stages:
  - set-variables

variables:
  SM_API_KEY: $SM_API_KEY
  SM_CLIENT_CERT_PASSWORD: $SM_CLIENT_CERT_PASSWORD
  SM_HOST: $SM_HOST
  SIGNTOOL: 'C:\Program Files (x86)\Windows Kits\10\App Certification Kit\signtool.exe'
  MAGE: 'C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools\mage.exe'
  SSM: 'C:\Program Files\DigiCert\DigiCert ONE Signing Manager Tools'

참고

"C:\Program Files (x86)\Windows Kits\10\App Certification Kit" is the path of signtool.exe and "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools" is the path of mage.exe

Client tools setup

Client control setup

Download and install the Keylockertools-windows-x64.msi using curl command given below, to invoke the client control from GitLab CI/CD:
