However, it does still need some more testing... sounds like you are volunteering

Sign me up!  More than happy to assist to improve time to market.

Hey Alan, what's the status of this branch. Can these features be used on prodnet yet?

They were going to be merged into the new version that includes the persistent blockchain updates, though that update has been slower (and I've been more distracted) than I expected.

Sure am! I'm just pulling the backupcenter branch into my clone now, then I'm going to test backup and restore on a new wallet first, and if that goes well I will do so on my savings wallet. It won't be my only backup, of course. Smiley

I'm curious what scenarios lead to a destroyed paper backup, but not USB/CD.

It is possible to put a paper sheet in an air tight plastic envelope. It can be done with little expenses at home with a laminator.
I found a wallet in a bathroom water tank a few years ago. It was there, in the cold water, for around ten years.
No paper money (someone took it before hiding the wallet). But the bus ticket subscription inside his plastic envelope was nearly perfect (and the plastic envelope was not water tight, it have a side open to change the ticket every month.
If it was laminated it would be as good as it was before being put underwater.

A printed wallet with stiffer material would be better than paper wallets. Something like www.bit-card.com.

this looks great, I can't wait. I'm not really tech-savvy enough to be much help with the testing, but I await eagerly for the release!

I am however mulling over the idea of a fire and water proof envelope w/ lock suitable for safely storing paper wallets at home. maybe with a magnet for hiding under or behind stuff, similar to those house-key hider-thingys. I saw it in a dream the other night, oddly enough, but it could be a nice real-world accessory. paper presents its own vulnerabilities, and strong boxes are just hard to stash and an invitation to theft.

i should probably begin by searching camping supply places, something like I described could already exist. still, you could probably market a branded "Armory" one for the die-hards ;-)

keep up the good great work!

If you think about it, just about anything that destroys paper, also destroys digital media.

Water:  paper will survive (it doesn't have to look pretty to be useful).   USB keys might survive, if you let them dry out 100%.  CDs will survive.
Direct fire: are goners
High heat (below 451 deg F):  Paper survives, CDs and USB keys probably won't
Bending & Stress:  Paper wins.  Clearly.
Shredding: paper at least has a chance here.  Good luck reconstructing a shredded USB/CD.

I'm curious what scenarios lead to a destroyed paper backup, but not USB/CD.   Or what would be a reasonably-inexpensive medium that could replace all this that would be more resistent to things.  Though, I think my point was that paper is far and away excellent without needing to search for other options.

I think you better tell users to be careful of case for the secure code.

or maybe just eliminate case and make the code longer.

I had considered removing case and making it longer, but I really wanted it to be shorter to avoid having it significantly increase the amount of data to write/type.  I already think it's too long, but I need to make sure it has some kind of sanity check, and enough entropy to be useful. 

On that note: at the moment, it's 7 bytes plus a 1-byte checksum displayed in base58.  That is 56 bits of entropy, drowned in 16MB of key-stretching.   56-bits doesn't sound like a lot, but the keystretching takes my i5-2500K about 0.25seconds to compute.  If you had just a single CPU working on that, it would take 580 million years to go through the possible keyspace.  Even with a multi-million-CPU botnet, you're out of luck.  And GPUs won't be very useful with the 16MB required per thread. 

I figured the case-sensitivity was okay, because I'm displaying it in such a huge font, it's obvious what is upper and lower case.   It can still be changed, though...

Also, I would remove characters like 1, I, i, 0, O, o etc. to prevent confusion.

Btw really looking forward to the M-of-N function, with this I can create my final, long-term Horcruxes. I'm thinking of adding one to my testament, since that document will probably be around pretty much forever (I believe there is a national archive of some sorts for these things). Thanks for all the great work!

Actually, base-58 already ensures that the font chars are distinct, so fair enough.  In fact, in many cases, you could correct case errors.

Another option is longer + more error checking.  Is the length convenience, or risk of a typo?

By the way, teaser shots of the new features, if you can't actually get in to use the program...
