Is it true that BitBay is closed source?
It's not entirely closed, just with changed variable names.
The source code is at
www.davtonia.com/bithalo/haloobf.zipThe variable names have been changed to prevent cloning but it can be easily audited and you can build from that.
Eventually i will put it on github. Like cryptohunter said there is no rush.
Basically anyone can check the source to see if it doesn't do anything nasty, but it won't work out of the box because dzimbeck changed some numbers around on purpose.
