PSPGP - PowerShell Module

PSPGP is a PowerShell module that provides PGP functionality in PowerShell. It allows encrypting and decrypting files/folders and strings using PGP. PSGPG uses following .NET library to deliver this functionality:

• PgpCore - licensed MIT

To install

Install-Module -Name PSPGP -AllowClobber -Force

Force and AllowClobber aren't necessary, but they do skip errors in case some appear.

And to update

Update-Module -Name PSPGP

That's it. Whenever there's a new version, you run the command, and you can enjoy it. Remember that you may need to close, reopen PowerShell session if you have already used module before updating it.

The essential thing is if something works for you on production, keep using it till you test the new version on a test computer. I do changes that may not be big, but big enough that auto-update may break your code. For example, a small rename to a parameter, and your code stops working! Be responsible!

IMPORTANT

This module works correctly on Windows/Linux and MacOS, but since it uses .NET STANDARD 2.0 library it requires minimum of .NET Framework 4.7.2 installed on a Windows machine when using PowerShell 5.1. Please make sure to keep your .NET Framework up to date on Windows Client/Servers.
