New tool - novault - Combines Monero Brain Wallets, Bitcoin Brain Wallets, and a Stateless Password Manager
I wrote novault some time ago because I wasn't happy with using browser-based brain wallets and because I wanted a single tool to handle all three functions (two wallets + passwords). Now, after happily using novault for several months I thought that it might be a good idea to share it with others. Besides the brain wallets and password management it has some extra goodies such as a silly name generator and a birth date generator. Using it is pretty simple: You invoke novault from the command line, it will ask you for a description and password, and place the result in the clipboard so you can discretely paste it into an application or web site. Here is a quick cheat-sheet of the basic novault functionality:
$ novault # Generate a password $ novault -w btc # Generate a Bitcoin address $ novault -w btc key # Generate a Bitcoin private key $ novault -w xmr # Generate a Monero address $ novault -w xmr spend # Generate a Monero spend key $ novault -w xmr view # Generate a Monero view key
novault has lots of other stuff too, check out the documentation. novault has some pre-built executables for Windows and Linux, no installation needed. They can be downloaded from here. Now that novault is public I wonder where to take it next: Turn it into a GUI? A mobile app? Should I add more currencies? Maybe refine the generator to deal with stuff such as stealth addresses? You feedback is welcome! And if you find any problems then please report them. My main motivation to develop novault started with my use of Monero, but since this is not a purely-Monero tool I opened a subreddit at /novault. You are welcome to comment to this post or open new ones in /novault. I'd like to continue and spend more time developing novault, if you find it useful your donation will be most appreciated: xmr - 44tLk21kgrQBMAuk41j8LURHxvo96sJfRhXR3ksJALwhrWs2YJK6uPCKbgwPpJcwefdKnZ766QeYbaDCmQ2rV7uBnVXRiz
I invested all of my Bitcoin to a brain wallet.... it's gone. Help me understand what happened?
So, I've been buying bitcoin for a while, little by little, and decided to create a "savings" account of sorts. I thought a really sweet way to handle it was to create a brain wallet. I used the tool here: http://bitcointools.appspot.com I memorized an arbitrary string of letters and numbers to create a private key and address. I found it super cool because this address has never been attached to a wallet of any sort on any computer, so I thought it'd be super freaking secure. If I ever needed any of its funds, I'd punch in the generated private key and attach it to a new wallet. Here's my address, created entirely from my memorized string of characters sent through one round of SHA256: https://blockchain.info/address/14kzRY5rLmXUwgM2ZKbMtWSfouuvpT2PAL I had 18.5BTC here. As of today, it's all gone. A transaction happened earlier today that I certainly didn't initiate. It was all sent to a brand new address I've never seen before, and the transfer of my BTC to this one is the only transaction ever for this other address. I'm wrecked. This is a ton of money, and I thought I had the safest solution ever using a brain wallet. The private key string of mine was not at all cryptologically inpenetrable.... however I can't fathom how it would have been brute forced or "guessed". It was a string of letters and numbers with a discernible pattern, but it is a string of characters that I guarantee have never been typed on the internet, ever, outside of the two or three times I typed it out on the bitcointools address to confirm that I wasn't accidentally sending my bitcoin to a black hole. Reddit, how does something like this happen? Is there some kind of absurd chance that the funds transferred to this new address somehow have an assocation with the private key that generated my original address? Is there some chance that the bitcoin appspot website tracks stuff people type to steal wallets? I'm even willing to share the damn private key string I invented to someone respectable in the Bitcoin community to help them do research on what happened. I have nothing to lose. This really, really sucks. I decided to be "safe" and put everything there, so that's all the BTC I ever had. EDIT: looks like the only logical explanation is that the bitcointools site is being run by a scammer. Why it took a month for him to steal my coins I have no damn idea, but I'm devastated. :( Guys, please upvote this so people can be aware to NOT create brain wallets using this damn site!! I've learned my lesson for the future. Once I get out of this state of shock, I'm going to get an encrypted wallet.dat, put it in a safe place, back it up, lock it up, and that will be the end of it. All offline. EDIT 2: to you guys who sent btc tips to me to help me return, I thank you very, very much.
The Jewish teenager behind over 100 bomb threats to Jewish centers has a Bitcoin wallet worth millions of shekels, yet we're being told to believe he has "severe autism" and a brain tumor which renders him incompetent.
Question: You end up in Cuba with no money, but you have 3 bitcoins in a paper-wallet/brain-wallet & your smartphone. How would you access it without a bitcoin ATM? Or is it simply not feasible considering there's very few bitcoiners there?
My friend was stuck in Cuba recently, and Western Union wasn't allowing funds to the transferred from his relatives in US or Sweden, the Banks wouldn't allow transfers either. Luckily he just had to cut-back his food budget to make the USD he brought last him the whole trip. Assuming my friend had a brain wallet with $5,000 worth of bitcoin, would this have helped him at all? Huge benefit of bitcoin is that it can cross any border, but what infrastructure needs to be in place to meaningfully use bitcoin?
Spending my day entering Nano S Ledger pin codes, trying to save my only bitcoin, could be on my Oculus Rift. Gentle reminder to keep your passwords safe and understand how to recover your wallet in case of brain trauma, natural disasters, etc
'Invalid PIN Code'. I'm unable to access my hidden wallet. It's the same PIN I've used many times before to check on my hidden bitcoins. I've entered it many times keeping close watch of my 1 btc, stored securely in my Nano S Ledger, waiting patiently for the moon. Today I was quite shocked when I received the error, 'Invalid PIN' after entering my hidden-wallet code. In haste I entered my 'Main PIN' and was able to gain entrance np. The problem is my 1 btc is in my hidden wallet! Since then, I've spent hours trying combinations of numbers hoping to find entrance. I do have my 24 word key, and I'm pretty sure I remember the 25th(required to recover hidden wallet), but I'm afraid to reset my Ledger without first trying as many PIN combinations as possible, with each wrong attempt I have to enter my main pin number. Also afraid I may have overwritten my hidden wallet with another hidden wallet with the same passphrase. How did this happen?!!? Appreciate any help. Will make a youtube video on my channel - Bitcoin Globe about the experience soon. Wish me the best on this recovery mission. 1)I've changed my PIN and have no memory of it (very possible, I've had a major concussion recently and for awhile took medications prescribed by doctor for PTSD ((tried a variety of pharmaceuticals all with horrible side-effects) 2) Someone swiped my bitcoin(did have a housemate living with me for awhile, he may have seen me enter my ATM pin which was also my Hidden wallet pin. Then I guess he would of had to change the PIN. 3)Technical Problem - this is honestly what is has to be, but I'm not ruling out the other options. Cheers! *Resolved thanks AUSSIEHASH!!!!
Bitcoin on the Brain. Bitcoin is thought of as a digital currency, but unlike Paypal or credit card, it’s equally suited to the analogue world. ... It’s the only bitcoin wallet that’s 100% ... Brainwallet.io is a deterministic cryptocurrency address generator for Bitcoin and Litecoin that runs in your web browser. It converts any text or file into a private key and public address, allowing you to store cryptocurrency on paper, in a password manager, within a photograph or document, or in your brain by memorizing the passphrase and salts. Typically, any Bitcoin brain wallet generator allows its users to key in random words (i.e. 4,6,8,12, or 24 words long) which is called a passphrase. This passphrase, depending upon the type of generator you are using, is hashed with SHA-256 or the Scrypt algorithm to generate a Bitcoin private key and then a Bitcoin public key. Brainwallet: brain·wallet / brānwälət / “A brainwallet refers to the concept of storing Bitcoins in one’s own mind.” While memorizing a Bitcoin private key is one way to store value, learning about the many ways public blockchains will change the world is an equally worthwhile investment. The domain of cryptocurrencies is a fast-changing world of innovation and opportunity. A brain wallet is a standard wallet that generates its address by hashing a passphrase to create a private key and therefore a public key and resultant address.. Seeing as a Bitcoin or a Litecoin address is usually a 256 bit string – the SHA-256 algorithm is usually used – although various levels of complexity can be added to this.. So if I wanted to generate a private address using the ...
