![]() Knowing the crypto APIs will hopefully be enough to figure out how to access the public key in the PFX file. 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. Aquí encontrará información detallada sobre el archivo e instrucciones sobre cómo proceder en caso de errores relacionados con cryptext.dll en su dispositivo. El archivo fue desarrollado por para usar con el software. Here are a couple of suggestions on reverse engineering cryptext.dll to see how it works. Por lo tanto, el archivo cryptext.dll dañado o inexistente puede afectar la ejecución fallida del proceso iniciado. 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. Alternatively, some programs, notably PC games, require that the DLL file is placed in the game/application installation folder.įor detailed installation instructions, see our FAQ.I looked into this a while to see if I could determine how the Cert Manager is able to open a PFX file.
