Encrypted Container on Asus WL500gP

[driest]

Hi everyone,
i've recently bought an Asus WL500gP and use it
to download torrents onto a USB connected harddisc.
Since i'm a little paranoid i want to encrypt the downloaded files.
I've already searched the web and this forum and the only solution
i found was using losetup to set up an XOR encryption. Since XOR
isn't secure enough i'm wondering if anyone managed to get
loop-aes, truecrypt or something similar to work with the WL500gP.

That is EXACTLY what I would like to do. I've searched the Internet in a vain, I just can't find any information about someone who has succeeded in doing this.

Any progress for you yet?

up!
is there any cryptsetup luks modules availible?

no, you'd need to compile them yourself, which is probably a little difficult since your router uses a 2.4 kernel instead of a 2.6

Another thing you might take into consideration is that encrypting it via the router is a terribly slow process. I don't quite expect speeds above 1MB/s

thank you for your reply
i have netgear wnr3500l, it works under 2.6

yes well the thread name is "Encrypted Container on Asus WL500gP"

anyway, then it might be easier

I just did that on wl-500gP v1 with custom rtn firmware (2.6.22.19, you can grab it here - http://wl500g.googlecode.com) with additional modules + compiled cryptsetup (which was the difficult part for me actually) cryptsetup_1.4.3-1_mipsel.ipk

1) So you'd need to build custom firmware with altered src/gateway/Makefile (to install aes.ko, cryptoloop.ko, sha256.ko, dm-mod.ko & dm-crypt.ko) & modify kernel config as well to build them
2) Install cryptsetup package (from the link I gave - dependencies will be installed automagically from Oleg's optware repository)

Yes, it's terribly slow to copy something into the container, but you can use it as a secure storage for router configuration for example. But I'm not sure if speeds would be slow on Netgear. I reckon it's bit better than 500gP.

$ dd if=/dev/zero of=1 bs=1M count=20
20+0 records in
20+0 records out
20971520 bytes (20.0MB) copied, 45.423548 seconds, 450.9KB/s

What would you expect from this hardware? Needs better CPU / more memory
