Bitcoin Wallet Encryption - what happens to backups??

Just curious here - I am attempting to tighten up security on my main wallet (will be transitioning to paper wallet or the ilk soon...but later)
I am using the official bitcoin wallet on my desktop.
I have a backup somewhere in the cloud from a year or so ago.
What happens when I encrypt the wallet on the desktop - does that in any way invalidate the old backup wallet.dat, that's kept in the cloud?
Or do I need to destroy that and re-backup my wallet?
Thanks friends

A simple, portable bitcoin wallet encryption wrapper (Windows only)

I noticed that most people are storing their wallet.dat files in truecrypt files, in virtual machines, on keys and copying them over to the standard directory when they use them. Though there is nothing wrong with this (except that most people are still putting it into the predictable, standard directory), it is very unnecessary. This program can be copied to any direcotory, USB, whatever, and when run will decrypt the wallet.dat using a password automatically, run bitcoin, and when bitcoin is closed, will re-encrypt the wallet file again. It uses a Rijndael Symmetric Algorithm and SHA2 hashes to ensure the file isn't corrupted.
To set up a new instance, simply extract the zip to any folder and run btcencrypt.exe. Enter a new password and bitcoin should eventually run. When you are done, close bitcoin and the program should notice and re-encrypt the wallet file.
To set up an instance with an already existing wallet file, do the same as above, but once bitcoin is fully running use the command 'replacewallet', and follow the instructions. The program should re-encrypt the new wallet file with the original password, and you can restart the program to continue using the wallet file.
USE THIS AT YOUR OWN RISK. I am not liable for lost unicorns or bitcoins. ALWAYS keep an UNENCRYPTED backup of your wallet.dat on a cd/USB stick
I have only made this today, any bugs please post them here. Download Link

Bitcoin wallet encrypted - old backups become useless?

When I encrypted my wallet (don't hate, it was encrypted before too, just not with this feature) today, I was presented with a warning to replace all my old unencrypted backups with this new one, since they become useless.
What exactly does that mean? My guess would be something about return addresses, and/or replacing all unused keys with new ones in the newly encrypted wallet, how far off am I ?
I can't find the answer anywhere, and would appreciate ELI5 type of an answer :)
thanks!

Online Bitcoin wallet encrypted with CryptoJS/Node using browser key, thoughts? /r/Bitcoin

Online Bitcoin wallet encrypted with CryptoJS/Node using browser key, thoughts? /Bitcoin submitted by BitcoinAllBot to BitcoinAll [link] [comments]

If you are the hacker who was using my computer the night before last and took approx 50 of my Bitcoins: nice work, seriously. Can you please return them? They were a combination of wedding gifts and years of saving. (info inside)

I’ve been thinking about all the ways you could have found the necessary passwords to get into my computer and actually be using it overnight. None of them too easy. You put some pieces together in a pretty clever way and worked around my many accounts with 2fa. You maybe even had privileged access to something in order to get my credentials including multiple passwords. Or maybe I was just galactically stupid and it wasn’t that hard afterall. Anyway. Wow.. Seriously, Kudos.
Funny story: you would have had more time browsing my computer & email (I saw you searched my gmail for “bitcoin”) before I killed the connection if you woudn’t have accidentally un-paused the TV episode my wife had paused before we went to bed. We heard the noise of a show across the house and got up. You had already gotten my wallet backup file though, you were quick, but I suppose you would have found much more given time.
The funds were comprised of wedding gifts and a not-insignificant portion of my salary invested over the past year.. and some hobbyist mining. This one really hurts.. like I got punched in the gut and betrayed by a friend.
To be sure you have the right person: Here are the 2 tx’s where you emptied my wallet
https://blockchain.info/tx/b90e41c6740f3a9fb9419e446deaa30b3183b4ca854fadf8dd441daad135b42f
https://blockchain.info/tx/5ae9903150beb1928ab63eb7362507a4ae7334642cbaa904f6d8e1ba7c773770
Here’s a signature of the title of this reddit post from one address from that wallet: 12V4dq4Y3sMk1WUmQSuiCA5wK8RPWAwMw7

And, here’s where you can return funds to me (some or all are much appreciated):

Thank you so much.. AND. Thank you for the life lessons. They are well learned.
Sincerely,
Well, you know who I am..
edit: Summary of lessons learned
edit: BTC-e is the exchange someone has identified as where my funds went. Any tips on contacting them or do you think they would cooperate? https://www.reddit.com/Bitcoin/comments/2mt0bu/if_you_are_the_hacker_who_was_using_my_computecm7dgvu
edit: Thanks to whoever you are that sent some bits my way. Your support is appreciated.
edit: Blockchain.info changed the email setting for new wallet signups just today - they no longer will send email backups unless you opt-in.

Why does Bitcoin Core generates a new hdseed after encrypting the wallet?

Wouldn't it be enough to just encrypt the current hdseed together with its current keypool?

Attempting to recover the old wallet part 2

If you remember, I was trying to recover an old wallet in this post:
https://www.reddit.com/litecoin/comments/9i3ijb/found_my_old_litecoin_wallet_and_it_may_save_my/
I had basically given up and then I found the original litecoin.dat file a couple of days ago and decided to attempt it once again.
Here is my current problem. I install the new Litecoin software, then delete the existing wallet and copy my old wallet in (and change the name to wallet.dat). However it now seems as though it doesn't actually import the wallet but is merely wiping it out completely - don't worry I have like five backups now.
Are there old windows binaries that I could download? I could try it on Linux but the required files are all out of date for a wallet with a date of January 2014.
Any help or ideas would be appreciated once again.

EDIT: It's been a little over a week and here are the things I have tried.
  1. Complete reinstall of blockchain, app, etc. - RESULT: When I replace wallet .dat with my renamed litecoin.dat is acts as though there is nothing there. However, I have pulled keys from it that don't import into anything I can find and it will unlock using the walletpassphrase command from the debug console.
  2. using bitcoinj - RESULT: I'm so lost, I can't even begin to know where to start
  3. using the tools here https://vicente-hernando.appspot.com/bitcoin-wallet-encrypt-decrypt-cipher - RESULT: It appears that you need to know all of the private keys and I am not sure this is viable. Also, while his English is good I was unable to understand some of the commands.
  4. using Wallet Key Tool https://github.com/prof7bit/wallet-key-tool/releases - RESULT: It doesn't really work with Litecoin all that well. There were about a hundred keys in there but none had dates or balances associated. I was at least able to verify that the password I have for the wallet does work.
  5. attempted to recover with "wallet-recover" as shown here: https://bitcointalk.org/index.php?topic=2668480.0 - RESULT: I get an error ./wallet-recover: 1: ./wallet-recover: Syntax error: "(" unexpected

I'm not really sure where to go next with this. I feel like I'm moving backwards now.

The best thing that you can do to help ensure success of the Lightning Network

A lot of posts have asked what can be done to speed up deployment of the Lightning Network. The answer needs to be learn, share, and implement strong information security practices.
I have noticed that there is very little discussion on what it will take to run a secure Lightning Network node. Many people do not appear to understand how transactions on the Lightning Network occur and how they're different from on-chain transactions. This is understandable, Lightning Network is complex, but without this knowledge it is likely that users will not take the proper precautions when engaging with the Lightning Network.
The number one thing you can do to ensure the success of Lightning Network is to make sure you and others are prepared for the security implications of running a node. This is especially true if you plan to relay transactions or intend to receive payments without manual coordinatation. The security requirements of operating a Lightning Network node are substantially higher than keeping your Bitcoin wallet encrypted or even of running a full node.
While the network is being put through its paces on testnet, make use of this time to learn and implement strong security practices. Testnet tokens have no substantial value so you can afford to make mistakes. Bad security habits formed now could leave you in an unfortunate spot once real money is on the line. Document and share the processes you use to deploy and manage a secure Lightning Network node. Build tools that can help make the process as easy and secure for others as possible.
Everyone who wants Lightning Network to succeed should consider making this effort their first priority, even above promoting Lightning Network itself. A rash of theft from first-generation Lightning Network nodes would have a devastating effect on confidence in the system.

It's out as often as you want to spend from it, like in any other cold-storage setup, isn't it?
Edit: You can have a permanent partition on the Tails system on which you can store the wallet/seed encrypted. The "flash storage is bad"-argument is still invalid, though, because you have to have a seed-backup (papemetal/brain/...) in all cases, no matter if you use a HW wallet or Electrum.
Btw, Electrum seeds are superior to BIP39 seeds. Nobody writes down the derivation path of their wallet. Everybody just notes down the seed. Thankfully, most wallets use standardized paths, but years down the road, who knows...? In Electrum, the version is encoded in the seed itself, so it truly does restore all information needed to access the wallets funds.

  • Lightning Network nodes are different than Bitcoin nodes. Your Lightning Network wallet will be a node. If you plan to use Lightning Network, this message is for you.
  • Transacting on the Lightning Network is an active process. Transferring funds requires that the sender, receiver, and intermediaries be online and accessible at the time it occurs.
  • If you want to receive payments without manual coordination, your node must be online.
  • Online Lightning Network nodes require access to the unencrypted private keys used to manage their payment channels. This includes the Bitcoin private keys used to commit funds.
  • Compromise of your node can lead to theft of your share of the balance on open channels.
  • There are other strategies that an attacker could use to slowly and quietly leech Bitcoin from nodes if compromise is not detected.
  • Lighting Network nodes broadcast their existence to the network. If hackers want to specifically target nodes, they have an easy way to find them.

Best way to really fully secure bitcoins? (with plenty of ability to backup wallets)

Hey guys, I want to get really serious about my bitcoin security, I'm willing to spend up to $200 to do this.
My thoughts were to buy a new, very cheap laptop, use it for nothing except installing a bitcoin wallet, encrypting the wallet.dat and leaving it alone (perhaps making some wallet.dat backups on flash drives, or emailing the encrypted wallet.dat to a specific 2fa email(with a unique password)
If you guys have a better solution or idea please share. Thanks in advance!

PSA: if you snail mail a wallet backup, make sure it's encrypted

This should go without saying, but I'll share my experience anyways.
I mailed a backup of my wallet to some (non-technical) relatives for safekeeping.
The backup was on an SD card. The SD card was in a little plastic case with an orange bitcoin sticker on it. I put both the SD card and a letter describing that the SD contained valuable Bitcoins in a plain white security envelope.
The letter arrived with the SD card missing. I was informed a cut had been made in the side of the envelope - just large enough to get the SD card out.
TL;DR post office workers steal shit out of mail. If you must snail mail a bitcoin wallet, encrypt it.
