Can't decrypt my encrypted rar!! Noooo

Hey there...

I recently encrypted a very large .rar file password protected as well. My master hard drive then died on me, and with my new one, I can't read the encrypted file as its a different machine (it thinks).

Is there anyway to bypass the encryption as i REALLY need these files!

Thanks

MK

  • No luck i'm afraid..

    I found it to use NFTS file encryption which is near empossible to bypass :(

    I am *so* screwed

    Is it some form of public key encryption?

    A search for recovery agent certificate might provide useful after reading this .
  • This is exactly why if you are going to use the file encryption in XP pro, you should backup your certificate under your xp user account. It won't read the file, because the new certificate is wrong (its not the same as the old one!). Its gonna be expensive i reckon to recover it, simple because there is no way you are going to break a 128-bit key (there are 2^128 or 340,282,366,920,938,463,463,374,607,431,770,000,000 possible keys, worst case) using just the processing power of you computer... and even if you connected a few hundred computers together you are still looking at longer than the age of the universe to check every key.

    The recovery agent certificate above assumes you HAVE a backup copy of your certificate (which comtains the necessary key to decrypt), which you can then use to decrypt files on another installation, drive or computer...which if your disk is unusable you dont, and can't access either...

    Encryption is meant to be secure, if it wasn't then people wouldn't use it :D
  • Have a look at Encrypted File System Recovery for some possible recovery programs and services, plus a fun-packed DIY method. However, unless you can recover certain data off your old hard drive you're pretty much stuck. :(

    Good luck though. :)
