Encryption Key export

Steve Mavronis · External Since: Jul 27, 2007 Posts: 7

I was messing around testing compressed folders and encryption options.
Anyway it was just a test and the folder in question doesn't matter to me.
But it prompted me to backup an encryption certificate key afterwards which
I did. Since this was a test only is it okay if I delete the pfx file? Or
should I save it if that is the only certificate key I'll have?

Thanks,

Steve

Hi,

Your backuped certificate will use to encrypting/decrypting to farther
operating so you can keep your backup - but not necessarily. You can get
access to it e.g. from Run -> certmgr.msc console and export keys any
moment.
Only need remember that if you reinstall your system, you will need recovery
your keys from backup.

Thanks but the key was made on a temporary test folder that doesn't exist
anymore. So does that key matter anymore?

Hi,

Certificate to encrypting is created when 1st time you cipher file or folder
and is used for next times. Even when your folder doesnt exist any longer,
certificate will still exist (in Personal container).
