I had encrypted my folder but I did not back up to get encryption certificate. After that, I installed windows again and I could not acsses these folders. Please help me!
So far I know is the encryption of bitlocker not trivial to decrypt without any encryption certificate. I think this would be a key feture for encryption software anyway. I see only one option for a quick decryption of your data. Visit Obama and say you are a very bad terrorist and have vital data on your drive. Then the NSA probatly would be so nice to decrypt your data for you. You only have "to ask" the right way. After you had been seen all the nice hotels of the NSA/CIA around the world you have your data back.
sorry but i think a low level format of your HDD is the best solution... ps before must save your data...
