laptop and secure data
Mike is correct in that using EFS to encrypt files or folders is one built
in solution though you can not use EFS to secure the whole system drive. I also want to repeat the importance of backing up your EFS certificate/private key to a password protected .pfx file on external media for safe keeping. Also keep in mind that if you leave your EFS certificate/private key on your computer that the EFS encryption is only as strong as your password. If you use a pass phrase that includes upper case, lower case, numeric, and special character such as those above the number keys on the keyboard AND your pass phrase is at least 15 characters long your password will be next to impossible to crack. Pass phrases should be easy for you to remember and leave the spaces in the pass phrase. A pass phrase such as "I always forget my 1 password!" is an extremely strong password. --- Steve "Simone" wrote in message ...

How and where can I keep the private key. Hi, I would not have used the builtin encryption that comes with Windows (EFS), to many things can go wrong with it. For a free 3rd party solution: TrueCrypt http://www.truecrypt.org/ quote Free open-source disk encryption for Windows XP/2000/2003 Main Features: * It can create a virtual encrypted disk within a file and mount it as a real disk. * It can encrypt an entire hard disk partition or a device, such as USB memory stick, floppy disk, etc. /quote -- torgeir, Microsoft MVP Scripting, Porsgrunn Norway Administration scripting examples and an ONLINE version of the 1328 page Scripting Guide: http://www.microsoft.com/technet/scr...r/default.mspx |

We use Encryption Hard Disk Plus from PC Guardian.
http://www.guardianedge.com/Encrypti...isk/index.html It is easy to use and is very secure. It does encrypt the whole hdd though, which in my opinion is better as you don't run the risk of putting sensitive data on a non encrpted partition.
