While a Logo-certified, Winqual-signed driver does not expire, test-signed drivers have an expiration date. The code that checks the digital signature examines the time stamp and verifies that the signature was applied during the valid time period of the certificate. If no time stamp exists, the code uses the expiration date of the certificate. Additionally, the .cat file remains valid as long as you do not modify the .inf file. |
