Re: [PLUG] USB-attached, hardware-encrypted card reader ... why vaporware?

Brent pretty much nailed my comments about hardware encryption.  I've used Iron Key USB hardware encryption and awhile back HP had a USB device with a keypad on it.  I don't trust small hardware to be be durable (the HP).  Iron Key's system, though robust, cross platform with KMS, isn't worth the money when LUKS give me this out the box which the encryption cipher I want.

Granted that only covers Linux and android but since its also possible to do a straight AES-256 container, I'm not sure why that can't be read by programs on OS-X or Windows.  As long as the software is not creating its own header, an AES-256 container is an AES-256  Seems like they should be plenty of programs that just do that- a quick search leads me to believe there are but I have not way to test the OS-X stuff.

The Ciphershed software looks interesting.

personally, i don't trust hardware encryption- it doesn't allow for tweaking or transparency, and due to the limited hardware onboard they tend to be fairly limited.

however, in the wake of truecrypt's journey into abandonware, there IS the cross-platform CipherShed,

give it a shot. i prefer LUKS via cryptsetup personally, but i don't have anything that necessitates cross-platform compatibility (and if it does, i just boot a liveCD that supports cryptsetup/luks).

i talk a bit about other volume-storage encryptions in the podcast episode i did here:

I'd like a USB-attached SD card reader that does hardware encryption.

Yes, there are hardware-encrypted, USB-attached flash drives[1], but
they are quite expensive and have fixed-capacity.

There's been a failed crowd-funded attempt at creating this

There's a company the purports to make exactly what I'm seeking[3], but
the product doesn't seem to be available for retail sale if exists at all
(no response from the company, no resellers, no recent updates, etc).

Does anyone know of a source for this kind of device, or have
speculation as to why it doesn't exist?
