2/4/2024 0 Comments Eureka cryptextParticipants are free to decide their technological focus and apply all year round, but the programme model is also used as an efficient platform for national funding bodies to cooperate and launch bilateral and multilateral calls for projects (sometimes thematic or based on a specific technology or market area) with dedicated funds. Network projects is Eureka’s original, flexible, bottom-up cooperation programme. By participating, organisations from 37 countries can access public funding for international collaborative R&D projects in all fields. EurostarsĮurostars is a funding instrument that supports innovative SMEs and project partners (large companies, universities, research organisations and other types of organisations) by funding international collaborative R&D and innovation projects. Because of their scale and the range of organisations participating, Cluster projects often develop highly advanced technologies and receive significant public-private investment. Each of the Clusters supports thematic communities comprised of large companies, SMEs, research organisations, universities and end-users. Knowing the crypto APIs will hopefully be enough to figure out how to access the public key in the PFX file.The Clusters programme facilitates funding for industry-led mid- to long-term R&D projects that can include organisations along a whole value chain. Step into that handler and see what crypto APIs it calls. Therefore it should exit the comparison loop and go to a handler for that verb. It should be in the middle of comparing the verb in question. It will probably be in a loop comparing the verb specified on the command line with each verb within the program. When the read breakpoint triggers, start stepping through the code that read the string. Put a read breakpoint within the DLL's memory on the first byte/word of the string containing that verb. Set the command line in the debugger to use the verb you found as well as your test PFX file. Then load rundll32.exe into a debugger (ie Windbg). Hopefully you'll figure out which is the right verb. Try running rundll32.exe using the verb(s) you pick with a PFX as input. Determine which verb(s) is most likely to support opening PFX files. You should see the various verbs indicated above. Dump the ASCII/UNICODE strings in the file. Here are a couple of suggestions on reverse engineering cryptext.dll to see how it works. The fact that it is a COM component means it is (almost surely) using unmanaged crypto APIs. So there's no obvious way to programmatically access it from. Based on OLEVIEW, it only implements the IUnknown interface. Although it contains an embedded typelib, using TLBIMP to create an interop assembly doesn't provide access to any interesting methods or properties. From the registry you can see which verb is associated with each file type.Ĭryptext.dll is a COM component. It is invoked using rundll32.exe along with a "verb". If you search the registry for cryptext.dll you'll see that it handles a lot of different file types (CERs, CRLs, crypto store, etc.). What I found is that cryptext.dll is the "Crypto Shell Extensions" and handles PFX files. I looked into this a while to see if I could determine how the Cert Manager is able to open a PFX file.
