    I run both... windows and linux.

    I was trying to create a new key on my windows machine (the only computer I had handy at the time), but was having trouble creating a 4096-bit key with any of the windows gpg programs.

    With linux, gpg seems to work a little smoother... I even have a mail client on my linux machine (clawsmail) that can encrypt/sign/decrypt/verify with my keyring within the mail client itself. I'm sure I could do pretty much the same thing with windows and outlook or something like that, but I've never tried it on windows - I prefer to use linux.

    That PGP client you downloaded from me yesterday has an Outlook plugin that will allow you to do that. I and a friend created 4096-bit keys but it seemed kind of useless to send practically 1MB just to say "Hi!."

    For encryption of individual files I use Cryptoforge which supports 448-bit blowfish. For my most secure files, I use a 28 character long alphanumeric upper case lower case key. The program encrypts at lightning speed.

    For encryption of an entire folder/directory, I use a program called "My Lockbox."

    Both of these are very easy to setup and use in WIN 7 and XP.

    i thought that when the PGP guy gave up his technology the government put a back door in it like they did with the security certificate companys, thawte and verisign. Could be wrong.

    Truecrypt, eraser, dban.

    With truecrypt you can do some clever stuff such as invisible archives, full disk encryption etc. There is a story about an encrypted Pc, not the best subject matter, but a young man in the UK is accused of having child porn on his PC. It has an archive on it and as far as I know the guy is still in jail for refusing to provide the pasword to the archive and the police haven't been able to crack it. The story is probably a couple years old now and the guy have been in jail almost a year by then. As I said, not the best subject. I fully expected the cops just to plant some stuff on there and get on with it.

    Eraser will clean disks of readable data. Just because you deleted a file doesnot mean it cannot be forensically recovered. Eraser has several option for disk overwrite. I believe the ideal number of times to overwrite data is about 24 times to ensure it cannot be recovered. It can take a long time to do 24 writes on a whole disk.

    dban. Need to check this name. It is basically a disk nuker. You can hit this app and it will trash your hard drive as fast as it can. I think you can run it silently.

    For secure file deleting I use shred. This command will give 25 passes. Here is my output for test.txt

    shred -n 25 -u -v -z test.txt

    shred: test.txt: pass 1/26 (random)...
    shred: test.txt: pass 2/26 (000000)...
    shred: test.txt: pass 3/26 (444444)...
    shred: test.txt: pass 4/26 (777777)...
    shred: test.txt: pass 5/26 (333333)...

    Re: The Encryption/Computer Security Thread!

    I figured that this thread could use a bump, as encryption and computer security is more important now than ever.
