Wheatworks Blog: Financial Matters

I wrote yesterday about Bruce Schneier’s Password Safe. I use it and I recommend it. It makes password security easy.

Today, think about the financial information you have stored on your computer. Is it in a spreadsheet in your “My Documents” folder? Do you have brokerage or retirement account reports saved as PDF files on your desktop? Is your tax return stored for any good hacker to see in your tax software’s data directory?

TrueCrypt, http://www.truecrypt.org/, is free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux. It is the best tool I’ve found to protect my financial information. I’ve used it for years and do not fear the loss of my financial data … or any other data, files, photos, etc. that I have encrypted. All my USB memory keys are encrypted with TrueCrypt and now (after the release of version 5 last week) my hard drives are too.

In fact, the BEST feature of TrueCrypt 5.0 is drive encryption. You can use TrueCrypt to encrypt your entire hard drive so that, without the correct password, no one can access your computer.

Caution: Even if you protect your computer with TrueCrypt, a weak password is a no-no. I use passwords of 20 random characters containing upper and lower case letters, numbers and symbols. Brute force efforts might crack them give enough time, but I have nothing that warrants the time a brute force effort would entail.

Here’s an example of a strong password:

With a strong password, TrueCrypt and Password Safe, you have a lot of what you need to protect your financial data. All three are free!
