Hi Chris,

No. A code signing certificate can be used for the length of time it is
for (1, 2, 3 or more years) and it can be used to sign unlimited number
of exe/dlls during that time. It just verifies who you are.

Yes. Any changes will require a code sign as it is embedded into the
binary file.

Best regards,
