Question about Password protection, encryption and 7zip

I have a question to you programmers...

You know that encryption need access rights so it is not really portable...

But everybody is requesting to password protect info in Pdrives...

So, is it posible to have portableapps and documents folders in a password protected 7zip file and when launching the Pmenu ask for password automatically, open the 7zip run apps, etc, and when closing, save changes in the password protected 7zip, erase the opened one with a secure deleter automatically (and then eject the drive)?

Just thinking in solutions... Wink

Very very slow

That would be very very slow. Unless you're on a portable hard drive. In which case it would just be very slow.

Sometimes, the impossible can become possible, if you're awesome!

Holding out

I've been holding off posting this info as I really wanted to compose a review of this USB portable hard drive, but I'm just not finding the time.

Anywho, if you really want protection for your files, get this drive.

Who knows...

The sad thing is, that this drive is one of the few solutions that offer a simple (o.k. here a real good one) password protection that is truely portable (in a sense of no admin-rights required). Another one is the Kingston Secure series (which even offers to choose from a fully encrypted drive - like the Ironkey - or a split one (partially-encrypted, partially public) which even makes it bootable).

The only software solution offering password protection without admin rights seems to be FolderLock. But it is payware and I do not know whether it can be trusted security-wise. The actual version 5.7.5 suffers from a severe bug which allows one to simply copy the programs folder to another place and thereby gain control over files that should be locked away. But I' ve been told that this will be fixed in the upcoming next version...

Don't like it

I don't like Folder lock because it doesn't let me autorun Apps directly from the folder when open it... Sad

Death Star Battle Plans on IronKey

Ha ha ha.... In fact I *do* keep the Death Star battle plans on my IronKey Smile

Seriously though, while the IronKey is super-secure, we did pay a ton of attention to making it easy to use, work in non-admin mode without software, making it very fast, and very reliable.

This turns out to be really difficult. There's a reason there aren't many great solutions out there. It took IronKey 2 years, 20 engineers, and many millions of dollars to build what they have. That included many months of 7 days per week, 16-18 hour days for the engineering team. It sounds easy, but it's really hard to deal with all the edge cases to make this kind of thing work seamlessly.

Private Disk

I use Dekart's Private Disk: www.dekart.com

Downside is that you have to have admin authority on a first run.

Benefits include: encryption on the fly, you can launch the Portable Apps Menu when the disk is unlocked and mounted, and easy to make a secure backup.

Best solution would be...

The best solution to security on all USB devices would be if Microsoft took the TrueCrypt open source code and built it in to the Windows platform. From a technical point of view, this would allow EVERYONE to mount a volume and a drive letter to store and retrieve documents securely -- no Admin access required by the end user.

Now, I do not know what licensing implications there would be for Microsoft to incorporate GPL licensed code, but wouldn't that be great? Just plug your USB into any Windows computer and bingo -- instant security for your apps and data.

only need truecrypt.sys to be loaded

Actually, now that I think about it, all Microsoft would have to do is include the "truecrypt.sys" driver and load it by default for my scenario above to work.

Microsoft supporting truecrypt

If Microsoft were to support TrueCrypt, you would still want hardware key storage to prevent password brute-force guessing attacks. Also you'd need linux and Mac to support it for true portability.

"hardware key storage to prevent brute-force guessing attacks ?"
What do you mean ?
are you implying that it is possible to brute-force
a 62-character pass-phrase without inventing some new energy-source first ?

OpenSource before Frozen Hell

Microsoft already uses OpenSource, though rather covertly.

If we know it is 62

If we know it is 62 characters, that definitely makes the job easier.

The trick is to make sure your passphrase is the last one tried in a brute force attack. If it is the first one I happen to try, it would have been only a few seconds to break in. Blum
