Now that real SIP (not gizmo) support has come to the N800, only one thing remains for me to be head over heels happy with my N800: Encrypted VOIP.

Skype does not count, as they are using a closed, and rather suspect crypto scheme.

Phil Zimmermann, the creator of PGP, has a free software tool out called Zfone (http://zfoneproject.com/). It's super cool, and plays well with all the SIP clients out there. It's open source (in fact, he doesn't ship a linux binary, only compile your own source).. and it needs an N800 port.

I really don't know what I'm doing when it comes to porting apps.

So instead, I'll put my money where my mouth is, and offer $25 to the first person who gets zfone working on the N800. I know it's a small amount, but I'm a graduate student. Hopefully, others will chip in too.

I hadn't heard of this before. Great idea. I've posted a bug to the rtcomm portion of the Maemo bugzilla as a feature request to add into the new built-in SIP client on the N800. You can find the feature request here: https://bugs.maemo.org/show_bug.cgi?id=1668

As a fellow graduate student, and one powered by a few high-profile internships and two very nice job offers, I'll take a stab at this one gratis.

I'll post updates here after I reconfigure my SDK and give this a shot.

Ok! Compiled and running in scratchbox. The UI is remarkably usable: I'm going to fix the menus, add fullscreen, and bind +/- to Secure/Clear, but it realigns itself horizontally.

The daemon requires the ip_queue module, so that will have to be built.

libzrtp relies on bnlib for high math, and bnlib has no ARM assembler optimizations. I technically have the number theory and general assembler background to do this: I'm going to instead hope that GCC does a good enough job.

I'm behind an extremely annoying firewall right now, so I won't get a release out today. That said, this seems to be a -very- trivial app to port.

Damn nice!!! I might have to upgrade after all

I emailed Phil Zimmermann about this, and he sent me back a copy of bnlib optimized for ARM.

aleksandyr, please check your PM for a url.

URL'd! I honestly hadn't even thought about searching around.

Still workign on it...

Update: packages built and installed.

However,

[ERROR]:ZFONED create: can't get ZID.

is all I can get out of zfoned.

Oh, and the bnlib-arm doesn't compile.

Turns out that error gets thrown when it can't find the built-in sound files. Whee!

So here's the pre-alpha story.

Grab:
http://users.wpi.edu/~chaos/zfone-armel-n800.tar.gz

I've included all the dependencies I know of that aren't the rtcomm platform.

You'll need to do all of this as root, for now.

Assuming you put the file in /media/mmc1/zfone-armel-n800.tar.gz

cd /tmp/
tar xzvf /media/mmc1/zfone-armel-n800.tar.gz
dpkg -i *.deb
cd /
tar xzvf /tmp/zfone-resources.tar.gz
cd /usr/local/
tar xzvf /tmp/zfone-resources.tar.gz

Yes, the resources need to be in two places for now. I'm not terribly skilled as far as debian packaging, as you can see!
---

You can now start zfoned as root by doing:
insmod /tmp/ip_queues.ko
zfoned
run-standalone.sh zfone

Caveat: I still have no work internet, so this is untried, but it seems to be working fine except for that.

Let me know how it goes
