From: Rick Marsh Subject: timestamping, how to
Simply digitally signing code with a signing certificate works, but it will expire unless timestamped. I have discovered how to timestamp code produced in Microsoft office, in particular Access 2003.
You must modify the registry as follows:
Create the following keys:
HKEY_Current_User\Software\Microsoft\VBA\Security\TimeStampURL (string) HKEY_Current_User\Software\Microsoft\VBA\Security\TimeStampRetryCount HKEY_Current_User\Software\Microsoft\VBA\Security\TimeStampRetryDelay
Set the URL to:
Note the spelling.
TimeStampRetryCount is a DWORD registry key value that is the number of retries the Visual Basic Editor will attempt to connect to the timestamping server. Try 3.
TimeStampRetryDelay is a DWORD registry key value that is the number of seconds the Visual Basic Editor will delay before retrying a connection to the timestamping server. Try 5.
After you have modified the registry, go on line, remove the signature and re-sign your code. It will have a timestamp.
Certum.pl is working for timestamping java codesigning see JavaCodeSigningTest for example
Timestamping service URL http://time.certum.pl/ Certificates to add to "cacert" java config file Certum CA : http://www.certum.pl/keys/ca.crt Certum TSA cert : http://www.certum.pl/keys/tsa.crt
Here is a bundle with the appropriate root certs to replace cacerts in jre/lib/security cacerts md5 : 05444dcc99687383ed165bd60f7da10f
An alternative to this method is detailed at JavaTimeStamping which does not require any changes to cacerts in jre/lib/security by the user. A timestamp CA cert is added to cacerts automatically by the applet itself.
