Re: Recovery of Encrypted files. help!


Thanks !!

Since I backed up my entire harddisk I presume that also the personal
encryption certificate (with its associated private key) and the recovery
agent certificate were backed up. Where can I find them?

If I would restore the the hardisk using MS backup/restore tool will it work?
