[ANN] CIYAM Safe - offline tx's using QR codes for comms

[CIYAM]

Do document the use of ImageWriter, especially for persons like me who've never touched SUSE. 

Good point - will be adding that to the distro description then.

It's loading up, albeit fairly slow on my HP netbook. I'm looking at the penguin pic with flying white particles on the screen for over 5 minutes now.

Yup - the *first* boot can take quite a while (subsequent boots are much faster) - am pretty sure as long as it doesn't "freeze" altogether it should be working.

Done, and I'm looking at a white console, logged in as 'tux'. Where should I proceed now? 

[CIYAM]

Done, and I'm looking at a white console, logged in as 'tux'. Where should I proceed now?  

Okay - the instructions are in "usage.html" (use Firefox to read them).

The first thing you need to do in the "console" is:

./install
and then

./init

(also don't stress about what User Key and Password you use - just make sure they are not empty and you write them down so I can check that they will let me unlock the "tux master" GPG private key to verify your work)

Nope, can't find the usage.html file in the home directory though. Running init now..So is this netbook meant as the 'airgapped' computer?

PS: the init script is throwing some warnings, but I think it's still going strong.

PPS: Found the usage.html after running init. Plowing through the information now...

Hmm... usage.html should be in /home/tux (file:///home/tux/usage.html - just checked on my offline computer and it is there - you did run "./install" and you got the right directory?) and *yes* the whole idea is that the offline computer only communicates to the online one via QR codes.

[John (John K.)]

There's no viewer for PNG files installed unfortunately. I'll go grab a viewer first...

Just use Firefox (File Open and select Images from the File Type) and Ctrl-+ to enlarge the size (and F11 for "full-screen" to make it even easier for the online computer's webcam).

The system fail to boot on both MSI WindPad 110w and ASUS EEEPC 900

On WindPad, no matter I choose "failsafe" or not, it crashed with a messed screen

On EEEPC, no matter I choose "failsafe" or not, after the penguin screen, it stopped at "[sdd] No Caching mode pange present" and "[sdd] Assuming drive cache: write through". About 2 minute later, the system reboot autometically

Okay - you did use ImageWriter to create the USB image from the .raw file (also note that this is a 32 bit image)?

[John (John K.)]

Okay, I'm done up to the generate new address stage, and all QR codes have been imported to my 'online' computer. I'm downloading kleopatra to verify the keys work. What should I do afterwards?

[CIYAM]

What should I do afterwards?

The next step is to send a small amount of BTC to the generated address and then create an unsigned tx (on your online computer) to send it back to yourself and then send this via a QR code to the offline computer - the "usage.html" details this (got that to appear yet?).

If you are still having troubles with usage.html then use: https://github.com/ciyam/safe/blob/master/usage.html (was designed as a <pre>...</pre> anyway so just as readable from there).

I'm actually reading the usage.html via github directly on my desktop. 

I'm having problems comprehending this part:

After bitcoins have been sent to the offline generated address to move the "unspent outputs" you will need to
construct one or more "raw transactions".

Do I first send some change to the address generated via a regular transaction? Then use the offline computer to send the change back again?

Yes, I use the ImageWriter for windows.

Yup - send say 0.0095 to the address and let the client add the 0.0005 tx fee (then the offline tx should be written to send back 0.009 to pay another 0.0005 tx fee).

[CIYAM]

Yes, I use the ImageWriter for windows.

Your "offline" computer is 32 bit?

[jl2012]

Yes, I use the ImageWriter for windows.

The windpad is 64bit but it has no problem in loading 32bit systems like android-x86 and windows

EEEPC is certainly 32bit only system

Hmm... am not sure why this would occur then (am not a "hardware" guy really at all) and am not sure how you could proceed from here but if the 10 BTC isn't dispersed within the next week then I will send you 1 BTC for your attempt anyway (sorry I can't be of more help but hope you understand that others could just follow up with the same thing).

[CIYAM]

John - please note that the "vout" is almost certainly #1 (not #0) if you are using the "reference client" (due to a bug with the way that change addresses are *not* randomly allocated in the [usual] case of their being 2 "unspent outputs").
