Trust My Msix!
Trust My Msix! is a Simple Command-Line App designed to import .cer files to the Trusted Root Certification Authourities Store in Windows in a few keystrokes! This speeds up the process of certificate importing for Self-Signed Msix Packages on Windows and it is very helpful to non tech-savvy users.
The .msix format is AWESOME and leaves far less traces and doesn't need pressing 'Yes' a 100 times. But an .msix is allowed to be installed if the Certificate is signed by a Certificate Authourity, and getting a Certificate from a CA costs Money ๐ต.
Normally Users have to go through the Import process of a Self-Signed Certificate which is TEDIOUS and CONFUSING, especially for Newbies. This tool makes this process take 1 second!

Installing Trust My Msix! from Winget :
winget install Chill-Astro.TMM
How she Works?
Transparency is the key Trust and you can't Trust Trust My Msix! if she wasn't Transparent!
-
She uses
certutilon Windows to import.cerfiles. -
The following command is used :
certutil -addstore Root <path> -
Of course making it easier for Newbies is better :
tmm -i <path> -
This command just saves developer hassle and encourages more hobbyists to make FOSS Apps.
