Windows certificate validation - Certificate Revocation List retrieval should be switched
off
For your security Objectif Lune digitally signs all relevant files with our own name and
certificate. The integrity of these files is checked at various times by different, context related,
methods. One of these checks, done during the installation process, uses the Windows
certificate validation check. .
The Windows certificate validation process not only checks the integrity of a file against its
signature, but also usually checks if the certificate itself is still valid. That check is done against
the current Certificate Revocation List (CRL), which needs to be retrieved from the internet.
However, if the machine in question does not have internet access, the retrieval of the CRL
must fail, which will lead to subsequent validation issues.
To circumvent such issues it is highly recommended to switch off the CRL retrieval prior to
installing Connect on machines without internet access. There is no security risk associated
with this, as the CRLs would never be retrievable without internet access, anyway. Advantage
of the switch will not only be found during the installation and operation of Connect, but also in
some speed improvements for any application which use signed binaries.
To switch off CRL retrieval on the computer, complete the following steps:
1. Open the “Internet Options” via the Control Panel
2. Select the “Advanced” tab and scroll down to “Security” node.
3. Uncheck the entry “Check for publisher’s certificate revocation” under that node.
4. Click the OKbutton to close the dialog.
5. Re-start the computer.
