    Once. Windows PowerShell 5.1 or PowerShell 7 on Windows, macOS or Linux.

    Install-Module ConsoleMonster -Scope CurrentUser

  2. Save the program

    Download it, or copy it from above into certificate-expiry.ps1.

    Download certificate-expiry.ps1View on GitHub

  3. Run it

    From the folder you saved it in.

    ./certificate-expiry.ps1

  1. Create a project

    A plain console app; .NET 8 or later.

    dotnet new console -n Certificateexpiry; cd Certificateexpiry

  2. Add ConsoleMonster

    The only package the program needs.

    dotnet add package ConsoleMonster

  3. Replace Program.cs

    Download it, or copy the program from above.

    Download Program.csView on GitHub

  4. Run it

    dotnet run

Or skip the copying. Every demo ships with the module and the project template.

Show-ConsoleDemo certificate-expiry
Get-ConsoleDemo certificate-expiry -Path ./certificate-expiry.ps1
dotnet new install ConsoleMonster.Templates
dotnet new consolemonster --demo certificate-expiry -n Certificateexpiry

Make it yours

Start with these, then read the rest of the file.

  1. Replace the fixed certificate list with inventory records and calculate days remaining before rendering.

  2. Set your urgent and warning thresholds, keeping the same policy in the summary and table.

  3. Assign renewal owners and a concrete next action for each certificate.
