Password Protection Excel

Hello,

I am keeping some sensitive information within a Microsoft Excel document. I know there is an in built password protection option however I know this is not that strong a protection.

Can anyone recommend a good alternative to password (file or folder level) that they could recommend?

Many thanks,

Regards,

If you are using Office 2007 or 2010 then the encryption used is stronger than 2003 or earlier. It uses 128 bit AES so is very strong as long as you use strong passwords.

To encrypt your document in office 2007:

1) Click on the Office Orb
2) Go to the “Prepare” section
3) Click on “Encrypt Document”
4) Type in your password and click OK
5) Retype your password and click OK

To encrypt your document in office 2010:

Click the File tab, then Click Info.  On the menu to the right Click Protect Document and Click Encrypt with Password.

Truecrypt is the tool of choice for transparent folder protection.

For mailing documents securely, I'd use WinRAR (not WinZip).

Elcomsoft do a long list of password recovery tools, but they don't yet do either of these....

All I would like to be able to do is either enter a password when accessing a folder in which the file is in or when the file is opened - and it be relatively secure.

I dont think from what I am reading that Truecrypt will allow this?

Truecrypt will do that.

Elcomsoft still offer a cracker for 2010, but x3man is right, the later encryption is tougher.

thanks x3man, I had not realised that it was much better in 2007/2010. I may well just try this.

DanCh99 - yes I can see how it does it but it, in my opinion, is not very practical or usable. It does not allow you to go to the folder and then be prompted for the password? The process of mounting and demouting etc will be very annoying and if I left it mounted what if someone simply accessed my computer and access the file? unless I have missed something.
