Third Party Module signature validity

We develop a module in Java for Ignition 7.8.4, so a code signing certificate is needed. Our code-signing certificate has 3-year validity.

According to our software developer, the module will run for 5-years after signature. However, we cannot find where do the 5-years validity come from.

Could you confirm the 5-year validity?

Thank you in advance.

Kind regards,

The 5-year validity period is embedded information in your code signing certificate, signed by whatever CA you got it from.

Ignition doesn’t use the expiration of the certificate to kill an installed module. It does reclassify such modules as self-signed in the gateway web interface when the cert runs out. When I renewed my code signing cert this spring, I rebuilt all of my modules to sign with the new cert, to avoid newcomers and upgraders getting a warning on install.
