Scripts for signing using KSP library on GitHub

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

smctl windows ksp register

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

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:

smctl windows certsync

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.

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.

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

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

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

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.

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

To integrate environment variables as GitHub secrets:

The values for these environment variables:

Command to set environment variables:

  shell: bash

To invoke the client control from GitHub actions

Download and install the Keylockertools-windows-x64.msi using curl command given below:

- name: Setup SSM KSP on windows latest
  run: |
    curl -X GET  https://one.digicert.com/signingmanager/api-ui/v1/releases/Keylockertools-windows-x64.msi/download -H "x-api-key:%SM_API_KEY%" -o Keylockertools-windows-x64.msi
    msiexec /i Keylockertools-windows-x64.msi /quiet /qn
  shell: cmd

To verify the KSP is registered, run:

- name: Register KSP
  run: |
    smctl windows ksp list
  shell: cmd

To sign with Mage:

- name: Signing using mage
  run: |
    mage.exe -sign <file_name> -CertHash <hash_or_cert_fingerprint> -a sha256RSA
 shell: cmd

To sign with NuGet:

- name: Signing using nuget
  run: |
    nuget sign <package folder> -Timestamper http://timestamp.digicert.com -outputdirectory <output folder> -Certificate Fingerprint <SHA1 Thumbprint> -HashAlgorithm SHA256 -Verbosity detailed -Overwrite
  shell: cmd

To sign with SignTool:

- name: Signing using signtool
  run: |
    signtool.exe sign /sha1 <certificate thumbprint> /tr http://timestamp.digicert.com /td SHA256 /fd SHA256 <file to be signed>
 shell: cmd

To verify a signature with Mage:

- name: Mage verify
  run: |
    mage -Verify <Path to signed .application file>
  shell: cmd- name: Mage verify
run: |
mage -Verify <path to signed .application file>
shell: cmd

The only input required here is the path to the signed .application file.

To verify a signature with NuGet:

- name: Nuget verify
  run: |
    nuget verify -All <output folder>\*
  shell: cmd- name: Nuget verify
run: |
nuget verify -All <output folder>\*
shell: cmd

The only input required here is the path to the signed folder.

To verify a signature with SignTool:

- name: Signtool verify
  run: |
    signtool verify /v /pa <Path to the signed exe/DLL>
  shell: cmd- name: Signtool verify
run: |
signtool verify /v /pa <path to the signed .exe or .dll>
shell: cmd

The only input for this step is the path to the signed .exe or .dll file that needs to be verified.
