Signed apps
A signed app has a certificate with a digital signature that confirms the app originated from a trusted server. When your system encounters a signed app, it checks the certificate to ensure that the app was created and signed by the individual who made the certificate. It also verifies that the contents of the app haven’t been modified or tampered with.
You can choose from these security options:
Trust: You trust the author of the app and want to run it.
Don’t Trust: You don’t trust the author of the app and don’t want to run it.
Show Certificate: Lets you examine the attributes of each certificate in the certificate chain. If you want to always trust the author of the certificate, click Show Certificate, then select “Always trust these certificates”.
