I’d love to hear from anyone using whole disk encryption. I’m carrying enough private data on my laptop now that I think it’s time to encrypt my data. That could be as easy as turning on FileVault, but I’m a bit worried about performance (my current laptop is an iBook G4 1.4GHz/1GB RAM).
TrueCrypt also looks awful good, with good reviews and a well-developed site and documentation.
If there’s no response, I’m gonna try both, one at a time, and I’ll report back here. I don’t usually do the flash drive thing, but I know some people who do, and they’re interested as well.
I’ve used TrueCrypt to encrypt external HD’s before, but not directly on a system disk. Performance was very good, pretty much the only limiting factor for me was the speed of the USB connection of the HD. I can say that TrueCrypt did a very good job for what I’ve needed it for.
Thank you, Scott. Good timing from Slashdot: How To, When You Have To Encrypt Absolutely Everything?
Like Scott, I’ve been using Truecrypt. I started using it about 3-4 years ago primarily as a sensitive information container/folder, but have recently (about 6-8 months ago) used the “Whole Disk Encryption” (WDE) to encrypt an entire laptop hard-drive (OS is Win XP) being used at work.
The WDE works great and I don’t notice any slow downs.
I’ve gotten spoiled with Truecrypt WDE on the Windoze machine – ease of use – and really wish Truecrypt had the same feature for Linux.
Cheers!
