Chastity device discussions and reviews discussion

Well, my KeySafe finally arrived today, and when I say finally, I mean it… So what is a KeySafe? It’s essentially a compact safe featuring an electronic keypad along with a key-operated safety opening mechanism. The electronic keypad has been ‘hacked’ so that the onboard computer, controlled by:81 manages everything. The concept is clever. You place your keys inside and lock it up; the only way to retrieve them is for the person in charge of the keys (the keyholder) to permit you access via website control. Sounds great… but there are some hurdles. To begin with, there’s just one supplier (who isn’t also the manufacturer), which from my experience led to delays, mixed-up communications, and several lost emails. While I get that manufacturers often drown in annoying or irrelevant messages, it seems this particular supplier might be a bit too aggressive about discarding them. In any case, after some faxes and over 50 emails, the supplier finally sent out the safe. SO I got my box at last. Once I received it, I did a bit of research and counted up the costs… bought from supplier - $550 parts - single board computer $70, safe itself $50, miscellaneous bits $50 software - free direct from the site.. a bargain! If you manage to get hold of one (which isn’t certain) and it’s programmed right (I had to rebuild mine from scratch), keep a few things in mind. a) The safe needs a serial port – something becoming rare on modern computers. b) The power supply will be American style (though they promised a European version early on). c) The website that controls the safe appears unmanaged and could vanish at any moment – which is tricky if you’re locked up when it does. So, what’s the verdict? Overall, despite being quite a headache to acquire and not exactly cheap (but then again, what isn’t in this hobby?), I still think it’s a brilliant idea. It would be nice to have less outdated configuration options, but that aside, it is one of the few methods to truly surrender control over your device securely. Not for everyone though. Although I’m pleased I (finally) got mine, next time around, I’d probably build my own and save about $500. Of course, if anyone wants me to construct one for them, just let me know. Now that I understand how it all fits together, it shouldn’t be too difficult, and I won’t charge triple the price either… lol

hey what would your rate be for building one of these keysafe devices?

> goozgazov said: > hey what would your rate be for building one of these keysafe devices? > Click to expand... Roughly £100. The main issue I’ve encountered is that the primary computer board seems only available in the US, so although the board itself is inexpensive, shipping adds a significant chunk on top.

Congratulations on getting it put together! I’ve always wanted one, but could never justify spending both time and money to build my own... well actually mostly the time. I’m lazy! lol. Do keep us posted on how you get along! mikecb

After the initial delivery and me having to basically re-program the unit from scratch (grrr), I thought, hey, I can do much better than this! So I headed down to Maplin's and picked up an identical safe for a bit under 30 quid, setting off on my journey of "doing better"... I’m planning two versions... The top-of-the-line version will feature a touch-screen controller with remote network access, email management functions, remote console oversight, web control alongside the front touch panel and wireless keyboard/mouse. The software is nearly finished; once it’s sorted out, I’ll set up an online demo. This Rolls Royce version will naturally come with a matching price tag if you want one (around £500). Meanwhile, I’m also starting work on a more basic model. It will share similar specs but should cost less than half as much since I’m using an affordable PC framework rather than a high-spec RISC controller. So why am I bothering? - Because it’s enjoyable to make - Made in Britain! - Network access without relying on obsolete serial ports - Fully stand-alone, not dependent on the original website staying alive - And mainly because it’s fun If there’s interest, I could sell pre-assembled units, but I don’t see this as a serious business venture (unless demand explodes)... lol

Please keep us updated on this. I think it’s a great project worth watching. I’m keen because I’m a geek and love gadgets! I AM a KeyHolder, so I don’t strictly NEED one, but I sure as hell WANT one! LOL

ooooo - was just reading up on the specs for the cheap board - gonna be running Linux and have 2 USB ports... I could stick a camera inside and use one of the I/O ports to turn a small LED light on so the keyholder can see the keys are really really inside! Neat!

Ooh, what board? I've been tempted to develop a few "remote control" type things, and a little mini linux board would be cool!

It's interesting to me how many of us on this site are the techy-type....

Google Blue Chip technologies - they do a nice 3.5" SBC with various touch screen options. They all have a healthy I/O feature but they are not cheep circa 150 -? 200 quid just for the board. I'm using the RE1 with embedded CE 6 as it's easy to program and have most of the server elements already ready for tweak. It can also run Linux - tried that and the mini screen I got with it didn't work (yet). I went for this as it can easily be bolted to the safe and doesn't need a HDD or fan! They do a neat N270 which will run any Windows or Linux but you need a HDD and a case to put it in. On the other hand, you could google for a UTX or USFF board and build up a mini system with a maplin (or general) I/O card. AAs the card is a specialist item, it more likely to cost more than the rest put together! As a training electronic engineer and computer programmer, I'm like a kid in a sweet shop here! * giggles *

Well, camera and touchscreen is nice to have, but isn't it a bit of over-engineering considering that just a simple control of a lock is needed? It should be possible to do this with a simple Arduino, a real time clock with battery backup, and a driver circuit for interfacing to the lock electronics. The Arduino has an USB interface for interfacing to an external PC, and can get it's power this way. The only downside I see with this approach is that the Arduino microcontroller is not powerful enough to control a properly authenticated encrypted link to the PC. This means that a MITM attack is possible, at least when the keyholder initially sets the password needed to control the safe. But later (for example if the keyholder wants to change lockup duration) CHAP can be used to avoid exposing the password to a chastity slave eavesdropping at the USB cable.

Why bother encrypting the USB link? If someone wants to steal a password a keylogger is a much easier way of doing it. If you were talking about a network connection I could see your point, but no way for USB.

Yes, I assume a network connection, as people with a local keyholder probably would not have much use for such a keysafe. So in my proposal, the Arduino is placed inside the safe (for obvious security reasons), connected to (and powered by) a local PC. This local PC is then connected to the keyholder's PC via the internet. The CHAP used to avoid the keyholder's password being sent in cleartext takes place between the Arduino and the keyholder's PC, as it cannot be ensured that the local PC has not been tampered with by the person kept in chastity.

The problem with this is for this to work securely, you need end-to-end encryption. There needs to be a tunnel between the remote PC and the Arduino. You'll need some kind of proxy on the local PC to transfer between the network and USB host, and a decrypted copy of any data can never exist on the local PC. It's a very round-about way of doing things. Putting an ethernet shield on the Arduino and using some kind of encryption on that would be the easiest and safest. SSL might be a bit too much to ask, but there are cyrpto libraries available. Using 3DES you might have enough room to make an SSH client, or maybe bodge up some custom protocol.

As I said above, I am doing this mainly for the sheer fun of it. Not everyone wants a Rolls Royce but some people do. That's life. If you can do it for a buck - 50, great. No worries.

Oh, just discovered the ComPort.dll needed to drive the KeySafe does not work with Windows 7 - 64 bit. As most new PCs come with this, I thought it may be useful information.

Wouldn't it be easier to most of this business on the software side of things on the chastity and KH computer? All you need in the safe is a solenoid and the means to power it.. you could have it powered by 120v and use a low voltage-controlled relay that interfaces with USB? Small simple board.. USB output controlled by software on the computer, sent a signal from the KH? I'm not especially techie, so I'll do my own research into this:)

why is everyone trying to suggest the easy/cheap solution? As I said before at least once, I am making a Rolls Royce all singing/all dancing keysafe for the hell of it - the technical challenge, the fun programming, the clever electronics. It's all in the hunt... I have a regular keysafe already. The one I'm making is a technical challenge. I am not making a business case for it. If someone wishes to have one, fine but the key element is the intellectual challenge of the hunt. I don't want an easy way... where is the fun of that? It's fun chasing down obscure code snippets or re-coding a dll just coz it doesn't do exactly what I want it to. The project is not about cheap and easy, it's about a Rolls Royce - or have I mentioned that already - not to mention, having something different and most probably unique.
