Ethereum Wallet Cracking

Ethereum Wallet Cracking

hashcat v3.6.0 was released yesterday and one of the newly supported hashes was Ethereum wallets ( Go Ethereum (Geth) , Mist and MyEtherWallet variants). This guide will show how a MyEtherWallet JSON keystore file is broken down, how its mapped to a hashcat compatible format, and finally an example crack. First lets get our wallet. Thats as easy as going to MyEtherWallet , entering a password, clicking generate and downloading it. MyEtherWallet suggests you enter a strong password (at least 9 characters). Firstly this isnt a suggestion it wont let you generate your wallet unless your its at least 9 characters. Secondly, I wouldnt say 9 characters is particularly strong, but thats an argument for another day. If you dont set a wallet name, a default is provided (as ours is) which comprises of the UTC time/date generated, followed by your new Ethereum wallet address. Our wallets password is [email protected]!and the generated keystore file can be found below which is coloured to show how its mapped to the hashcat compatible format.

Litecoin Vs. Ethereum: The Differences | Genesis Mining

Litecoin Vs. Ethereum: The Differences | Genesis Mining

Litecoin Versus Ethereum: Understanding the Differences Litecoin is not a new player in the digital market; in fact, its nearly as old as the well-known cryptocurrency bitcoin. An increasing number of people, however, are turning to this type of digital currency, entrusting their money and wallets to math instead of a centralized authority. Tyler Winklevoss, co-creator of Facebook, said, We have elected to put our money and faith in a mathematical framework that is free of politics and human error. There are many cryptocurrency options available, but bitcoin and litecoin blockchain technology are a couple of the oldest. One in particular is capturing a lot of attention, and thats ethereum . The network has quickly risen to become the No. 2 cryptocurrency in the world, even though its practically a toddler, launched only in 2015. But what are the differences between litecoin and ethereum, and which is better? Here are a few of the major differences to consider between two of the largest cryptocurrency influences in the world. Litecoin is strictly a cryptocurrency , which means that people use it mainly to conduct transactions. The currency can be mined, as can bitcoin; however, its sole purpose is to serve as a digital currency. Ethereum also functions as a cryptocurrency, but it provides a network capable of creating smart contracts and crowdsourcing funds for new projects. The infrastructure decentralizes the management structure and includes a smart contract, which is basically a computer program that runs the entire organization. A funding period can be set for a new organization, and once that goal is met, people can create proposals for the next steps. Everyone then votes on the proposals. The number of votes allotted to each person is tied to the number of coins Continue reading >>

What Is Scrypt? | Cryptocompare.com

What Is Scrypt? | Cryptocompare.com

Scrypt is a memory hard key-derivation function. Memory hard functions require a large amount of RAM to be solved. This means that a standard ASIC chip used for solving the Bitcoin SHA-256 Proof of Work would need to reserve a certain amount of chip space for Random Access Memory instead of pure hashing power. Scrypt just adjusts the number of random variables that need to be stored compared to SHA-256. Scrypt creates a lot of pseudorandom numbers that need to be stored in a RAM location. The algorithm then accesses these numbers a few times before returning a result. Generating the numbers is computationally intensive and as they are accessed a few times it makes sense to use RAM in conjunction with hashing power rather than generating them on the fly a time and memory trade off in terms of optimising speed. The main advantage of scrypt is that it lowers the advantage of ASIC Bitcoin miners in the network. This then means that there should be the possibility of more miners joining the network and contributing sufficiently to make it worth their while. Another possibility is there is less energy use as the total network power is less. Continue reading >>

Bitcoin, Ethereum Or Litecoin: Which Is Best For You?

Bitcoin, Ethereum Or Litecoin: Which Is Best For You?

Bitcoin, Ethereum or Litecoin: Which is best for you? A primer on the most visible cryptocurrencies. Before you jump into this overview of a few cryptocurrency alternatives, check out our first two articles in this series, Bitcoin, explained and Buying and selling bitcoin . Bitcoin has spawned hundreds of cryptocurrencies. Bitcoin was the first. Since its release in 2009, it's become the most famous, established and valuable cryptocurrency. But it's not the only game in town . Litecoin followed in 2011. Created by Charles Lee, an engineer who later helped build Coinbase , the leading cryptocurrency exchange, Litecoin is based on the same code as bitcoin but with a few tweaks designed to address two of its predecessor's limitations: transaction speed and access to the mining process. And in 2015, Ethereum made its debut, incorporating bitcoin's basic blockchain premise and Litecoin's pursuit of faster transaction speed, but adding a few of its own twists -- including the ability to process little chunks of code, called "smart contracts" -- and on its virtual peer-to-peer network as opposed to a dedicated server or mining rig. Ripple's market cap now exceeds $40 billion. Coinbase's support for bitcoin, Litecoin and Ethereum -- as well as Bitcoin Cash , a new branch of the bitcoin blockchain created in August 2017 -- helped install and keep them among the most visible and well-capitalized cryptocurrencies. Rounding out the top 10, in terms of market capitalization, is a dynamic shortlist that has included established coins and upstarts like Ripple , Cardano , Neo , Stellar , Eos and IOTA . For the purposes of introducing some of the prevailing concepts behind the growing population of cryptocurrencies, we'll take a closer look at the technologies behind Litecoin and Ether Continue reading >>

First Ethereum Asic Miners Released By Hminers

First Ethereum Asic Miners Released By Hminers

First Ethereum ASIC Miners Released by Hminers Miami, FL, September 01, 2017 --( PR.com )-- HMiners ( ) is now making a strong impact in the global cryptocurrency market with their three powerful mining rigs that have already proven their efficiency in Bitcoin, Litecoin, Dash, and Ethereum mining. The company claims that these are the first ever mining rigs that can run on SHA-256, Scrypt, Etehash, and X11 mining algorithms. Using the H2U Miner, H4U Miner, and Rack Equipped with 5 x H4U from the company, many users have already been able to receive a 100% return on their investment within just one month. In the language of technology, an algorithm is defined as a self-contained sequence of actions capable of carrying out data processing, calculation and automated reasoning tasks. SHA-256 stands for Secure Hash Algorithm, and is the most commonly used algorithm for Bitcoin mining. Scrypt is a multi-layered algorithm that is faster compared to SHA-256 because of its capability to set the hash size to a smaller number, and is used extensively for Litecoin mining. X11 is a relatively new algorithm known for its extraordinary energy-efficiency while mining with a CPU or GPU. The most advanced of all, Ethash is the Proof of Work hashing algorithm for Ethereum mining. Though the field of cryptocurrency has experienced significant developments over the years, not much has been done so far in terms developing mining rigs capable of mining Ethereum. The team at HMiners has spent months in evaluating, prototyping, and extreme-condition pressure testing their three miners before starting their mass production. The most noteworthy feature of these products is their ability to mine Ethereum with extremely high hash rates, while maintaining low power consumption. Many Ethereum miners Continue reading >>

How To Calculate Estimated Profit Using Hashrate?

How To Calculate Estimated Profit Using Hashrate?

How to calculate estimated profit using hashrate? Profit is calculated via the deduction of expenses from income. The income consists of daily payouts which size depends on the hashrate. In order to calculate an estimated income using the hashrate you will need to include it in one of the calculators below (set all Power values to zero): 3. Ethereum - for ETHASH (set all Power values to zero) 4. DASH - for X11(set all Power values to zero) 5. Zcash - for EQUIHASH(set all Power values to zero) Next, deduct the maintenance + electricity fee of 0.0035 USD per 10 GH/s of SHA-256and0.005 USD per 1 MH/s of Scrypt from the income. ETHASH,X11and EQUIHASH contracts are not subject to any fees. The sum you end up with is your estimated profit. Continue reading >>

Ethereum Kdf - Scrypt #1228

Ethereum Kdf - Scrypt #1228

Note that Ethereum default is 256k:1:8 and not 256k:8:1. That may explain the difference between 17H/s and 13H/s. When I run JtR against a 1k Wordlist on my 4770k it takes 1m22s with 256k:1:8, but 1m12s with 256k:8:1. So that would be "only" 12H/s but there's some startup time involved that should be subtracted so I think 13H/s is correct for JtR. Also note that I am using MPI (mpirun -n 8) - not OpenMP. From my experience with JtR, MPI gives the best performance (it may be different with SCRYPT based algorithms). As a comparison, hashcat takes 1m18s to process the same system, same wordlist and the same hash. That is almost on par with JtR performance. The reason why I wrote hashcat was ~20% (it was actually ~40% but I didn't want to overact because it was not fully finished) is because I compared hashcat performance when I was in the middle of the development and compared only the SCRYPT part but without the surrounding PBKDF2 and the Keccak round. From my perspective that was ok, because on GPU the PBKDF2 in SCRYPT (and in this case also including the raw Keccak round) take about no time compared to the SCRYPT part, I didn't even come on the idea it will be different on CPU. The same list was processed in only 57s. I think the large data part (1k of data) is it that bloats up the PBKDF2 around the SCRYPT. Hello @jsteube , retail versions of the Radeon Pro SSG cards with upto 1TB of on board nand memory should be shipping very soon. Do you think this hardware development marks a game changer for scrypt hashing rates and what kind of hash rate would you estimate if hashcat were to run against this card? I would be wiling to purchase a few of these units and donate access to them. Thx That is because GPU are fast only when utilizing all of it's compute hardware in para Continue reading >>

How To Mine Litecoin And Other Altcoins

How To Mine Litecoin And Other Altcoins

CoinDesk Launches 2017 Year in Review Opinion and Analysis Series While it is now considered too late for hobbyists without expensive ASIC processors to start mining bitcoins , many of the alternative digital currencies are still well suited for mining on your home PC. In this guide, well take you through all you need to know to start digging up a few litecoins, feathercoins or dogecoins without any costly extra equipment. For the most part, cryptocurrencies employ either SHA-256 or scrypt as their proof-of-work hashing algorithm, but many of the newer currencies have opted for scrypt. Row of Gridseed litecoin miners set up. Copyright: Arina P Habich Scrypt tends to be the more memory intensive of the two however, home PCs with reasonably powerful graphics cards can still mine those cryptocurrencies quite effectively, as there are no dedicated ASICs to compete with yet. Perhaps surprisingly, its still possible to use just your computers CPU to mine some of the digital currencies. This holds true, even if you have only a laptop with integrated graphics; though this may not prove terribly effective and is not a set-up we would recommend. Before you start mining, you will need a wallet to keep your hard-earned coins in (see our guide to storing bitcoin ). A good option is to head to the homepage of the currency you intend to mine and seek out the download link for the default wallet app. If you would like to do more research into litecoin specifically, we have a guide on how to get started. If you find yourself in need of help and advice, most altcoins have community forums, as well as their own subreddit . The majority of wallets are based on the original Bitcoin-Qt client. Be warned, though, that before these wallets are truly usable, you may face a lengthy wait while t Continue reading >>

What Is Ether?

What Is Ether?

Ether is a necessary element a fuel for operating the distributed application platform Ethereum. It is a form of payment made by the clients of the platform to the machines executing the requested operations. To put it another way, ether is the incentive ensuring that developers write quality applications (wasteful code costs more), and that the network remains healthy (people are compensated for their contributed resources). If you just want to test the technology, you probably don't need real ether. Download the latest Wallet app and switch to the Test Network Check your ether presale balance safely here: The total supply of ether and its rate of issuance was decided by the donations gathered on the 2014 presale. The results were roughly: 60 million ether created to contributors of the presale 12 Million (20% of the above) were created to the development fund, most of it going to early contributors and developers and the remaining to the Ethereum Foundation 5 ethers are created every block (roughly 15 seconds) to the miner of the block 2-3 ethers are sometimes sent to another miner if they were also able to find a solution but his block wasn't included (called uncle/aunt reward) Note that after the Byzantium update is implemented, the mining and uncle reward is reduced to 3 ethers and 0.625-2.625 ethers, respectively. No. According to the terms agreed by all parties on the 2014 presale, issuance of ether is capped at 18 million ether per year (this number equals 25% of the initial supply). This means that while the absolute issuance is fixed, the relative inflation is decreased every year. In theory if this issuance was kept indefinitely then at some point the rate of new tokens created every year would reach the average amount lost yearly (by misuse, accidental key Continue reading >>

The Ethereum Project's logo, first used in 2014 Ethereum is an open-source , public, blockchain -based distributed computing platform featuring smart contract (scripting) functionality. [2] It provides a decentralized Turing-complete virtual machine , the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. Ethereum also provides a cryptocurrency token called "ether", which can be transferred between accounts and used to compensate participant nodes for computations performed. [3] "Gas", an internal transaction pricing mechanism, is used to mitigate spam and allocate resources on the network. [2] [4] Ethereum was proposed in late 2013 by Vitalik Buterin , a cryptocurrency researcher and programmer. Development was funded by an online crowdsale between July and August 2014. [5] The system went live on 30 July 2015, with 11.9 million coins "premined" for the crowdsale. [6] This accounts for approximately 13 percent of the total circulating supply.
