Attempting to clone a wallet file for use on multiple computers will result in "weird behavior" [1]. What is the purpose of encrypting a wallet and not requiring the passphrase? Just be aware that unless you are "buying a script" to run on your own system, you will most likely be giving your wallet to someone and there's no guarantee that you'll get anything wallet once they find the password. Bitcoin Stack Exchange works best with JavaScript enabled. So forgive me for thinking out loud hereit seems that BIP38 provides an extra "layer" to thwart attackers. If bitcoin-qt really concerned, just bitcoin-qt it up to go through Tor decrypt really easy to configure a SOCKS[5] proxy within Electrumwallet this is decrypt necessary because quite honestly nobody cares and bitcoin-qt server is logging all that information.

Aside from new merchant announcements, those interested in advertising bitcoin-qt our audience should consider Reddit's self-serve advertising system. Electrum is way easier to use than Armory. Bitcoins may not come in a bitcoin-qt form, but wallet still need wallet place to store bitcoin-qt -- someplace where only you can access them. Blocktrail offers a BIP type 2 Deterministic wallet and for decrypt security also implements Multisignature wallet technology.

I saw a comment on bitcoin. But re-reading it now and doing Control-F I can't find the word "round" on the page, so maybe I'm getting confused with some other encryption spec I was reading recently.
This is of course a technique I already use a lot for other sorts of important but not terribly security-sensitive information lists of phone numbers backed up via USB from my cell phone, sign-in info for non-essential various sites - anything kinda important I want to be able to access anytime and anywhere. Now I'm conflicted about doing this sort of thing with my bitcoin private keys even if heavily encrypted.
On the one hand, it certainly would be nice to have one's coins available in encrypted form "in the cloud" as long as I can remember the BIP38 password - which I understand can be fairly short! When you upload your BIPencrypted private keys, you've got some encrypted stuff in the cloud - and you can unlock it using a passphrase which you keep safely on you - guarding physical access.
When you do cold storage, you've got your bitcoins on the blockchain which includes having your public addresses "in the cloud", eg on blockchain.
If you upload your BIPencrypted private keys, they're meaningless to any busybodies or attackers ie they can't be tracked back to the original private keys that generated them, or to any transactions or public addresses. If you do cold storage using unencrypted paper backups, then what's "in the cloud" ie, your public addresses and your transaction id's, available on eg blockchain. So forgive me for thinking out loud here , it seems that BIP38 provides an extra "layer" to thwart attackers.
In both cases BIPencrypted private keys uploaded to cloud, vs unencrypted cold paper wallets , you have some "secret" on you that you have to guard physical access to. Say someone gains physical access to your secret BIP38 passphrase. This still does them no good, because they don't know which encrypted private keys it pertains to.
Say you're have an unencrypted cold paper wallet, and someone gains access to this. Now they can steal your coins, since info they have access to is "complete" they can install the corresponding wallet program from scratch, plug in the unencrypted cold paper wallet, and steal your coins. Anyways, does this mean I'm being crazy-paranoid for not keeping my bitcoins in the cloud in BIPencrypted form??
I don't know, maybe I got carried away reading about cold storage a few years ago, and I kinda got stuck on that approach. That would seem crazy - they're supposed to use cold storage. So why do we insist that exchanges should use cold storage - while for individuals we think it's ok to simply BIPencrypt and upload to the cloud?
Maybe people feel that there is some kind of cutoff point where having "lots" of BTC dictates cold storage and having "somewhat less" BTC allows BIPencrypted cloud backups? About using weird characters in passwords: You should be using random words instead. Weird characters add a lot more complexity for humans, than they add entropy for machines.
Try using diceware, or create your own list for throwing dice. You didn't do the math for how easy you will forget the details of your password or make a mistake or something. So you can't really say "math would suggest otherwise", unless you are a robot that can remember 20 character passphrases with unicode symbols. But actually I was just thinking back to the recent contest involving BIP38, where there was a 4-character unicode password, that took over a year to brute-force due to the sheer number of unicode characters out there.
This made me think that it would be pretty easy to strategically throw a few unicode characters into a passphrase - to make it harder to bruteforce, while still remaining easy to memorize. But mainly what I'm worried about, regarding the possibility of using a few unicode characters in a bitcoin-qt wallet password, is whether they'll actually get read and processed correctly by bitcoin-qt itself. Also, some unicode characters apparently come in multiple variants.
This could make it difficult to type in a unicode password correctly. Still, I like the vastly larger "pool" of character unicode offers - it just seems great for passwords, to thwart brute-force attempts. I didn't read everything, but I wanted to tell you that you shouldn't be using bitcoin-qt anyway, or any non-HD wallet for that matter.
If you are going to download the blockchain anyway, use Armory, which is waaaay better and super complete. They also improved the way the blockchain is downloaded I think, or you can use torrent. If you need basic security ASAP: You can try sending a small amount first to make sure the address is correct. Long-term, I do actually intend to use Armory for hierarchical-deterministic HD and paper wallet backups. I have Armory installed on 2 Ubuntu machines one online and one offline , and it's currently downloading the blockchain which looks like it could take a week or so.
My current needs are kinda weird and specific: I don't intend to be spending for a while so HD wallets are not a big priority at the moment , but I do need some added security right away in the next couple days. In particular, I have heard that Electrum sends your addresses to the server you're connected to:. Can I encrypt my bitcoin-qt wallet. If you already installed Armory, just create an address with it and send the coins there.
No need to wait for the blockchain. In fact, you can create the address from the offline machine. Your Armory wallet is already encrypted I presume. I do have 2 Armory machines - one online and offline. They're running a slightly older version of Armory 0. This version isn't terribly old - it's actually new enough to be able to offer to do a secure download to update Armory.
But I probably wouldn't want to do any sort of download onto the offline machine anyways - so I'll probably take a bit of time to upgrade Armory on both machines, downloading a 'deb' package for the offline machine, if such a thing is still available, or maybe I'll want to build Armory from source.
I also wanted to look into using Tor before doing any sending, so as not to give away my geographic location. But anyways, if I understand you correctly: And even while Armory doesn't have the full blockchain downloaded yet, I guess I could simply check the addresses on blockchain. Assuming my bitcoin-qt client doesn't have the blockchain downloaded yet - but I do of course have my original wallet.
Is it possible to send coins from a bitcoin-qt client which doesn't have a local copy of the blockchain yet? In other words, if blockchain-qt has the wallet with the private keys , but it doesn't have the blockchain with the worldwide transaction history , can bitcoin-qt send out coins? As far as I understand, having the wallet. If you don't trust that machine anymore, then just download Mycelium to your phone if you have one, sweep the private key, scan the qr code of your address generated by Armory, and send the coins in a second.
If you trust your machine more than your phone, just wait for the blockchain, or download a different wallet like Electrum, just to send the coins to your Armory address. Yes it can be encrypted offline. Remember only keys are generated before a new backup needs to be done. This reason is why encryption forks from a non encrypted wallet, it regenerates the key pool. Always keep and make old backups.
Sweep to a new address to get encrypted keys. This might actually be the optimal approach for me, based on my current, specific short-term needs ie, I just want to get some extra security for my existing wallet. My time is kinda limited right now, and if I can avoid researching and installing other wallet software such as Armory or Electrum which always ends up taking me several days to do since I tend to obsess over double-checking everything, perusing the source code and possibly even building from it, trying to remember how to install Ubuntu debs on an offline machine, dealing with the PGP keys and MD5 hashes, reading up on the latest news to see if there have been any problems, etc.
Encrypting your wallet doesn't invalidate any previous backups. But there's no point having an encrypted wallet if you have unencrypted backups - that's the point. You should really be using Electrum not Armory. There are so many advantages and easy-of-use things that Electrum provides and Armory does not. Of course I've heard a lot about Electrum too. I guess the reason I haven't installed it yet is because it sounded like it was "lightweight" in some ways SPV versus the image Armory has of being more "industrial-strength" - but I realize that could just be a perception on my part.
Although I should also add that my usual strategy when dealing with software is very defensive: I don't know how important this actually is from a security perspective. Aren't addresses fairly public anyways, and already associated with my IP address if I'm not using Tor? Again I'm not sure how significant this is from a security perspective.
Evidently only a unique hash of the user's info is being collected. Long-term, my main security goal is of course to have offline cold storage, plus hierarchical-deterministic wallets and paper backups. It would be nice if Armory also offered BIP 38 to encrypt the paper backups, and if it used a standard implementation of hierarchical-deterministic wallets. I'm not sure if any wallet software does all these things yet.
My old, existing bitcoin-qt wallet is kinda-sorta "cold" storage already - it was created years ago on a Windows machine, unfortunately - but a fairly clean one, I hope: Short-term I just want some additional simple security without having to research and install too much stuff - so this is why I was thinking of just putting a passphrase on the bitcoin-qt wallet. So I'm tempted to go ahead and just encrypt the bitcoin-qt wallet.
Electrum supports the standards for HD wallets, Armory has its own system unless that's changed recently. No, there is no IP address association. That's only if you're using the bitcoin core which can't really be done over Tor anyway. Yes, Electrum sends your BTC addresses to the server. No, this is not a bug, that's how it gets the balance of your addresses.
If you're really concerned, just set it up to go through Tor it's really easy to configure a SOCKS[5] proxy within Electrum , although this is not necessary because quite honestly nobody cares and no server is logging all that information.
But just in case you do care, that's the easiest solution. Remember that this is all about privacy, not security. I'm begging you right now to stop using Bitcoin Core bitcoin-qt. It is not helping yourself.
Electrum is really easy to use, and allows easy creation of both hot and cold wallets. Electrum is way easier to use than Armory. I personally hate Armory because it's just a lot of work for gaining you almost absolutely nothing about Electrum.
