Hello,
I'm finding a problem making sure my cold storage wallet is secure.. I find that the only loop hole in cold storage is making sure that the address generated in the offline pc are really random..
I can think of several issues:

1. a ubunto developer change the source code so that all users that create new address in bitcoin will create address from a pool of 200 million address  ( so each one will get a different one) but the developer know the keys for all of them

2. downloading a bitcoin-qt client that new address generated from this client is from a pool of 200 million address ( so each one will get a different one) but the bitcoin-qt developer/hacker will have the keys for all address.


What is the best way to be absolutely sure my address is random|?
Has anyone ever thought about this issue?


Thank You.

How bitcoin-qt generate address and how do I know they are really random?

Thanks.

Hello I was wondering how multibit is creating new address? Is it possible that multibit author can make it so that all addresss that will be created is known to him? Then he can take all the bit coins..

Hello...

[[EDIT] As some pepole requested I add a option for different arg when pc Is used and when Pc is IDLE ... So now the tool is different]

Hello ,
I'm the famaliy pc manager and I always fix all of my family pc when they broke..
So I have access to allot of pc must of them don't have a good gpu and mining in them is not worth while..
But some are pretty good, I wanted to mine in those pcs only when the pc is idle (so not to make truble) and to make the minning totally invisible
It took me some time but I made a app that is totally configurable and that will run what ever program that you want after X s when the pc is IDLE

[EDIT] As some pepole requested I add a option for different arg when pc Is used and when Pc is IDLE ... So now the tool is different

You can use it..

If you have any advise , Or request all is welcome

There are two version's windows xp/ vista and windows 7 ( This is becuase removing the trayicon is different )

The program is divided to two part the SWIsetup.exe and ProcessSwi.exe

SWIsetup is the setup gui..
and ProcessSwi is the monitor of the computer idle time and start the other app that you want after X idle time exc...

screenshot:


Program = the program directory  ( Click v to browse)
Idle Opt arguments = Optional command-line arguments  to run with the program when the pc is Idle
Not Idle Opt arguments = Optional command-line arguments  to run with the program when the pc is not Idle
autostart with windows = If the check-box is clicked then ProcessSwi will start in windows startup
start program invisible = This option will make the program you want SWI to active invisible or not
Run Program when = Here you choose when do you want the program active (Coputer Idle/Computer Idle and not Idle exc...)
ProcessSwi = show you if ProcessSwi is active or not .

after you finish with setup and saved you can close SWIsetup.exe

exemples:


New Version:(13/6/2011)
1.03
* Now you can choose if to install the program for all users in the PC or only current user.. (Require admin )
*Fix a bug

Make Sure you uninstall previous version's from the startup!!


If you do not believe that the exe is same as source code you can compile it yourself with this compiler:
