Accidentally encrypted my certificate

#1
I encrypted the /Users/{username}/AppData/Roaming folder, which, I discovered afterward, contains the certificate needed to decrypt it. I have not forgotten the password used to encrypt and to login. Is there any possibility of decrypting the folder or the certificate?

I'm not sure if this will help, but it's an excellent tutorial on the subject: http://www.vistax64.com/tutorials/99959-encrypt-decrypt-folder-file.html. Reading it, you may note at the beginning there is a link to a 3rd party program (it's a trial version so use it to fix the problem and then cancel the trial) for difficult situations and yours seems to fall into that category. You can check the rest to see if anything helps, but I suspect you'll end up coming back to needing this program. There's no guarantee it will work (although the list of what it can do is impressive, it doesn't specifically include encrypting the certificate - but it's certainly worth a try).

I hope this helps.

Good luck!

I know what you mean. It was the %AppData%\Roaming\Microsoft\Crypto that has caused the problem, and you know it! As I think you already know, that file stores the local key containers. Hopefully the above link will work, otherwise we will have to think about other strategies. I suppose you could try a System Restore, although I am not too sure that this will fix the problem.

Have you tried to just decrypt it? I see your problem though.
