You have a PowerShell script that is being used on 1000 workstations.

 Conjur Summon is an open source utility that can fetch secrets from Conjur and export them as environment variables to a sub-process environment. This way, the secrets are not exposed or stored in the script, but are only available at run time. To use Conjur Summon, you need to install the summon-conjur provider on each workstation, define the secrets in a secrets.yml file, and wrap the PowerShell script in summon. For example, if the secret ID is win/domain/cred, the secrets.yml file would look like this:

DOMAIN_CRED: !var win/domain/cred

And the summon command would look like this:

summon --provider summon-conjur powershell script.ps1

This will inject the secret value of win/domain/cred as an environment variable named DOMAIN_CRED to the PowerShell script. The script can then access the secret using the $env:DOMAIN_CRED syntax.
