Client Certificate Download Utility - cert2src

TinyCLR OS
1

I have published a basic command line utility for downloading and exporting the chain root certificate required for TinyCLR OS to access secure sites. This eliminates the need to download them manually from a web browser.

Certificate can be exported in Security Certificate File Format (crt) commonly embedded as a binary project resource or source code added directly to a project as a byte array. Also, using build tasks this utility can be used to automate updating project certificates on build.

I wanted to share in case anyone else finds it useful. Here are a couple usage examples:

C:\project>cert2src.exe https://www.google.com --path

-----BEGIN CERTIFICATE-----
