Certificate manager plugin for Carbide: http://developer.symbian.com/main/downloads/files/Symbian%20Certificate%20Manager%20Plug-in%20for%20Carbide.c++.exe. This tool is integrated with Carbide to provide management for your DevCerts. It incorporates an improved version of DevCertRequest.
Known issues:
1. The tool is undocumented
2. The tool is hard coded to expect the existence of the folder: "C:\<localised name of Program Files>\Common Files\Symbian\Certificates". This is a defect because this filename is only partially localised ("Common Files" is hard-coded, but will have a different name on non-English machines). The result is that you will get errors like:
Import has failed!
The certificate file cannot be copied to the database.
The workaround is to manually create the above folder
In this Plugin a file named devcertreq.exe can be found.
Where can I get the source codes for this?
(note: this executable seems to use OpenSSL, licensed as GPL)
