即使没有网络连接，签名脚本如何工作？

Question

I have signed the powershell script with the key purchased from Verisign (symantec).

I am executing the script inside a VM where no internet connection available.

How it executes without any problem? How it will get public key if it is not connected to internet?

I am using executionpolicy as "AllSigned"

Answer 1

The signing certificate you got from Symantec is signed with a trusted key, which is likely already stored on your computer. Use mmc.exe and add the certificates module to the console. Browse the trusted root CA container, and you are likely to find several certificates from Symantec / Verisign or whatever. One of those is used to certify that the signing certificate you purchased is really from the issuer.
