what is meant by encrypting a file (in vista)?

Question

and is it necessary to follow this "back up encrypted certification and key" that windows prompts me to do? if it IS necessary, could i just click "next" all the way, without customizing specifications (like checking particular check boxes, etc.)? i really have no idea about this. please help. thanks!

Answer 1

When you encrypting a file its contents will be changed to non human readble format. It is an added security.



Encrypted certification and key is used to decrypt the contents in to original format.



If it is loss you cant recover that files normally. (Losses related to your user account. System Administrator can decrypt your files)



Backup encrypted certification and key is best.

Answer 2

Vista can be set-up so that every file in your account, on your hard drive, is encrypted with a standard encryption. Anyone without your account password can't just copy your hard drive and use your files. It's intended to stop internet hackers, and physical thieves as well. Sorry, I don't have Vista, so I don't know what the settings are.

Answer 3

encryption is to encode a file.

To put a code on in case you want to lock it out from prying eyes.

The reason for the back up is in case you forget the code...

Just don't forget where you put the backup.

If you are not worried about people going in to your house to use your computer, then I wouldn't worry about it...
