This also means new best practice is sending to offline wallet using an address created on there. Previously I got an address from the watch only copy.

Interesting, to say the least.

Is that being added to the next version or already in the current version?

There's no new feature per se

Can you explain this a little further? AFAIK, the addresses generated on the offline wallet and the watch only copy are the same? Wouldn't be of much use otherwise...

A virus can compromise your watch only copy to generate addresses that aren't yours. This completely bypasses all security.

You could generate it then glance at the cold storage copy to make sure it's in the list. You may have to generate extra ones to get the number of addresses the same.

Is that a malware, or a bug in Armory?

Malware, armory is solid.

He has 2 of these. One that is "online", used for email signing and encryption, one marked as "offline" used for release signing. Also you could try to verify the bitcoin signature.

How would I get an "offline" key?

Basically there's an attack they can't talk about yet, just get updated. The attack makes armory generate addresses from the virus.

Which key are you verifying against? You should have Alan's offline signing public key in your key ring before doing this.

The one hosted at MIT? I do and it is marked as trusted.

What am I doing wrong to verify the file?

It looks like the key file is right?

It is not necessary to upgrade any offline computers just to check wallet consistency.

How do we do that from the Armory menus? Or just restart Armory?

I have upgraded to 0.91.1 and it checked for my wallet consistency when i started it. Guess i don't have to do anything else.

Notice it says not necessary

If all your hot wallets and watching-only wallets have been loaded on 0.91 or 0.91.1 before, and no notification popped up, no further action is required. I would guess that 99%+ users will pass this check without issue. And of those cases with consistency issues, the recovery tool can fix most of them.

Will post more information about this soon. Working on getting an announcement page up and distributing notifications to older versions.

Somehow I understood that an upgrade isn't necessary, but we still needed to check the wallet consistency. I got it now. Thank you.

This is already supported by the lockboxes! All parties in a lockbox can be offline keys, created separately and independently. Each party individually manages their own wallet holding that key, including all the regular methods we have backups... yes you can do a 2-of-4 lockbox between 4 parties, and each party can do a 3-of-5 fragmented backup of their individual wallets (which hold the key).

Cool, I need to do some forum searching.
