Windows 10: I want to repair a corrupted .pfx certificate file

Hi,I deleted a .pfx certificate file that was on my usb key. But I lost access to the copy I made. After recovering it, it appears to be partially corrupted. I seriously need it to access a lot of important work again that was encrypted with EFS. Could some expert take a look at it to see exactly how much it is corrupted and maybe find a way to repair it?Thanks a lot

Windows changed my PFX certificate - Old certificate will not import

Windows 10 Pro
Version 2004
Build 19041.928

Hey guys. This is the second time my Windows machine has decided to change my PFX certificate on me without asking/warning. I have an external HDD with files that are encrypted with a PFX file that I created in 2018. About 6 months or so ago, I couldn't access any of my files. Digging into the issue, Windows had switched my PFX certificate to a new one that I never generated. I guess the system generated it on its own. I was able to restore my old PFX certificate and access the files again. (Thank you backups!!!)

Fast forward to today. It has happened again. My Windows system has switched to a new PFX file that was generated last month. I still have my old PFX certificate, but now I am getting an error when trying to import it. I can no longer access my encrypted files.

Here are some screenshots of my issues:

 

Corrupted file RAR

If the archive has been created using WinRAR, why don't you try WinRAR itself? It has a built-in repair feature for repairing corrupted archive (ZIP as well as RAR). Follow the steps given below:

• Open WinRAR application in your system.
• Now click on File tab > Open or simply press Ctrl+O.
• A small window "Find Archive" will pop up. Locate the corrupt RAR archive from your system directory and select it.
• Now click Open button.
• Click Tools tab > Repair archive or simply press Alt+R.
• Again a small window "Repairing File name.rar" will pop up.
• Now click Browse to select a location to save the repaired archive.
• Check the box "Treat the corrupt archive as RAR" and click OK.
• WinRAR will start repairing of corrupt RAR archive. Once it gets completed click Close.

I hope the above steps will help you repair the corrupted RAR archive.

Thanks.

 

Error in Certificate Installation (PFX) 0xC0000225

Hi, I have also tried exporting the certificate and key container (.pfx) from Windows 8.1, but with no luck for my Lumia 920. Then I found a solution
by filtering the pfx file through openssl. This process removed the "Microsoft CPS Name" Bag attribute, and now installation worked perfectly.

Now I am stuck at not being able to decrypt my emails. The phone reports that the certificate cannot be found. And all signed emails are being reported as invalid, even though I have both mine and the
senders certificate chains installed on the phone.

I haven't heard about the WP 8.1 update 1. Is that available for my Lumia 920, or do I allready have it? Anyway, we still need a sanctioned
solution from Microsoft on this!
