Quote from: Emeraldshop on October 08, 2012, 10:57 pmI use a computer just for business purposes, and I have it's drive fully encrypted with Symantec's pgp desktop. The question is... in case the police one day broke into my home, would they be able to discover the files inside, and use them against me in trial, or it's impossible to recover them if you don't know the password? The best real world test of PGP's desktop encryption was a few years ago, with the case of Sebastien Boucher. Boucher was a French Canadian who lived with his father in Vermont. They were crossing over from Quebec to Vermont, when a Customs and Border Protection (CBP) agent noticed a laptop on the back seat of the truck. The laptop was powered up (it had been hibernated, as opposed to shut down). The agent noticed that there was a drive Z with a fiar bit or porn on it, some of which appeared to be child pornography. Boucher was read his rights, and the laptop was seized. Some time later the laptop was powered down completely, and later submitted for examination by a CBP forensic examiner. It was at this time that they realized that the drive Z was actually a PGP Desktop encrypted volume, and was inaccessible without a passphrase. Boucher was asked for the passphrse, and refused to provide it. The Feds hammered away at that volume for between a year and a half and two years, without any success whatsoever. For more details see the Wikipedia page on Sebastien Boucher. https://en.wikipedia.org/wiki/In_re_BoucherQuote from: Emeraldshop on October 08, 2012, 10:57 pmAnother one: For a while, I used my personal computer for business purposes which I tried to keep relatively clean, erasing all the files involved with business. Is this enough, or should I fully format it, and shred the free space?Thanks!!If you're really worried about being raided, you should DBAN the drive. Formatting alone isn't enough. http://www.dban.org/
