Using Vault To Build An Ethereum Wallet

Using Vault To Build An Ethereum Wallet

This is a guest post by Jeff Ploughman, a Security Architect at T. Rowe Price and founder of the DC-Baltimore HashiCorp User Group this work was done in his role as an Ethereum aficionado and open source contributor. HashiCorp Vault focuses on keeping application data secure across distributed infrastructure by tightly coupling your trusted identity with brokering access and managing sensitive organizational information and secrets. An Ethereum Wallet is a gateway to decentralized applications on the Ethereum blockchain. It allows you to hold and secure ether and other crypto-assets built on Ethereum, as well as deploy and use smart contracts. This blog will look at how the two can work seamlessly together. Ethereum, like many blockchain-based ecosystems, is fundamentally a decentralized technology. The protocol was designed to place little to no trust in 3rd parties like cloud providers, certificate authorities, or DNS. The blockchain that underlies Ethereum is replicated on every node in the network so that the loss of any particular node (or subset of nodes) is not impactful. The fundamental innovation of blockchain is how distributed consensus is achieved without trust. And while there are endless debates about the efficiency costs of this trustless model or the overall utility of blockchain, I am more interested in the practical ramifications of this decentralized architecture. The foundation of all blockchain ecosystemsthe "crypto" in the currencyis the system known as public key cryptography. And while the public portion of a key pair may be disseminated in a decentralized manner, the private key is a fundamentally centralized concept. This fact has caused a bit of an impedance mismatch: it often feels like the centralized nature of private keys is an afterthoug Continue reading >>

Guide To Cryptocurrency Wallets: Opening A Myetherwallet (mew)

Guide To Cryptocurrency Wallets: Opening A Myetherwallet (mew)

Guide to Cryptocurrency Wallets: Opening a MyEtherWallet (MEW) We simplify complexities By Aziz, Founder of Master the Crypto No responses This guide will cover in great detail on the process of opening aMyEtherWallet (MEW) Wallet. This is an extension of our previous Guide to Cryptocurrency Wallets: Why Do You Need Wallets? Keeping your Coins in an exchange can present a real risk of you losing them all. Why? Simply because you do not technically own the coins youve bought in an exchange . Exchanges work like a bank; it is a third-party service provider that you trust to keep your coins safe. However, there is always a probability of the exchange shutting down or being hacked, resulting in a loss of coins (case in point: Mount Gox exchange). Given the lack of regulatory frameworks on exchanges and cryptocurrencies as a whole as well as the infancy of the industry, the best way to keep your coins safe is to have total control of your coins . Having real and true ownership of your Coins means that you control your own private keys. And the only way you can control and manage your private keys is through owning your own wallet. Since many ICOs these days are in the form of ERC-20 tokens, the main base currency for participating in an ICO is through Ethereum (ETH) coins. (See also: Coins, Tokens & Altcoins: Whats the Difference?) In order to participate in an ICO, you have to open an Ethereum-compatible wallet. The most common Ethereum wallet is MyEtherWallet . It is simple to set up and provides the security benefits of coin ownership. This guide will explain the steps needed for you to open your own MEW wallet. Before we move on, its important to understand key terms associated with a wallet. (Read also: Beginners Guide to ICO Investing: How to Participate in ICOs ) Mak Continue reading >>

How To Make A Paper Ethereum Wallet

How To Make A Paper Ethereum Wallet

Oliver Dale on November 2, 2017 / 0 Comments It is highly recommended to create an Ethereum paper wallet as one of the safest methods of securing your cryptocurrency. Essentially, an Ether paper wallet is a record of your Ethereum Wallets Private and Public keys which you need to access your wallet and make transactions. Possessing a piece of paper with a code on it and calling it a wallet may come off as a little weird to some. However, it is the safest method you can employ to store your precious Ether coins. Paper wallets provide an extraordinary advantage over other conventional cryptocurrency storage techniques. Imagine the comfort you will feel knowing that your Ether can be stored safely in your house, deposit box, or safe or even buried in your backyard. Advantageously, the paper wallet isnt part of the internet. Therefore, no hacker can ever gain access to your precious cryptocurrencies. A potential thief would have to crack your safe or dig through your whole backyard to find your wallet and cryptocurrency information. A Paper wallet is perfect for people who wish to keep their Ether in cold-storage that is, un-connected from the internet and safely stored away. With a paper wallet the speed for transfers and exchanges, as well as the overall speed at which your Ether becomes available, is greatly reduced. This is due to the coins having to be relayed back to an online wallet before they can be utilized. If you wish to use your Ether at am exchange or for speculation purposes to make some money and benefit from market price fluctuations, then your Ether always has to be readily available. For those purposes, an online wallet is recommended, at least for the sake of efficiency. However, if you plan on sticking with your Ether for the long run by being a Hodler Continue reading >>

Among the most popular of these wallet services is MyEtherWallet. MyEtherWallet is an incredibly lightweight, fast, easy to use wallet for Ethereum. You can access MyEtherWallets services through: The reason why MyEtherWallet supports a large amount of access methods is because it merely acts as an interface to the Ethereum blockchain. All of these methods simply pass along the required information needed to verify you to MyEtherWallet, which in turn provides you with a clean, user-friendly connection to the blockchain. This makes MyEtherWallet as easy and fun to use as a web wallet, but as secure as Ethereums Mist browser. This is because youre storing your private keys locally (on your own device) instead of on a potentially vulnerable, centralized web server. Of course, via the methods above, you can choose to provide your public key via a wallet service you may already be using or create a new private key, JSON file, and/or mnemonic phrase. Its important to emphasize the fact that MyEtherWallet is not a bank. It doesnt store your private keys, JSON files, mnemonic phrases, etc. for you. If you lose these methods of access/recovery, youre out of luck. Remember to store your private, critical information in a safe and secure area. In this guide, we will be covering how to create and set up a wallet through MyEtherWallet, as well as how to access this newly created wallet using a private key and keystore file. How to create an Ethereum wallet with MyEtherWallet The simplest and most straightforward way to set up and use MyEtherWallet with Ethereum is to head over to MyEtherWallets website and create your own wallet.

It is important to understand that all wallets are in the blockchain, and the apps that you are familiar with or may have hear of (e.g. ImToken, Mist, Metamask, etc) are just different apps that connect to your wallet in the blockchain. Some of them hold your credentials for easier access, but in the end, they connect to the same place. You can think of them as different gateways that connect you to the same point on the blockchain.

Ether Paper Wallet Tutorial - Step By Step Instructions

Ether Paper Wallet Tutorial - Step By Step Instructions

You should create an Ether Paper Wallet, before you start buying or mining Ether. An Ether Paper Wallet is just like an ordinary wallet which is printed on paper. It might sound weird at first, however, it is the safest method to store your Ether. The fact that, your Ether can be stored at your house, at the bank in a locker box or in a cookie box buried behind your house, is an important advantage of the Paper Wallets, if compared to an Online Wallet. The Paper Wallet is not part of the Internet. No hacker can gain access to your precious Ether. Unless, he would find your cookie box behind your house. A disadvantage of the Paper Wallet is the fact that, the availability of the Ether is belayed as the Ether has to be transferred back to the Online Wallet before it can be used. The use of the Ether Wallets always depends on what you want to use them for. If you want to trade your Ether at the stock market and benefit from price fluctuation, the Ether has to be ready to use in your Online Wallet in order to act quickly. If you want to go with a long-term rise in the market instead, you can keep your Ether safely in your Paper Wallet until you need them and then transfer them online. By the way, Paper Wallets are an excellent extraordinary present. Just put enought Ether in them. We use MyEtherWallet , a client-based Open-Source JavaScript-Application. This is a web page where you can check the way this service works and therefore increase the safety. In the following, we will show you the main functions: How much Ether is available on my Ether Wallet? 2. Choose a password for the encryption of the JSON file: Enter a safe password in the field. We recommend a combination of at least 15 characters of capital and lower case letters, special characters and numbers. Take a no Continue reading >>

How To Recover A Lost Wallet #396

How To Recover A Lost Wallet #396

As long as you remember your account password this might not be a problem. Your wallet and keystore data will be stored in %APPDATA%/Ethereum. Type that into a command-line shell to see the full path. I recommend making a backup copy of the keystore folder in there (as explained in ). After doing that you could try deleting %APPDATA%/Ethereum and then running the latest Mist (0.5.2) to recreate the folder with fresh data. You could then copy your keystore backup into the new %APPDATA%/Ethereum and restart Mist to see if it picks up your account. this is really frustrating, my computer crashed, I reinstalled the OS thinking if I have the password and the address I will be fine, I am not a computer geek, does this mean I lost my ethereum, all? I invested a lot of money in this technology and now I am told that I lost it all. I have my password which I thought it will be enough to "log in" back if I reinstall the wallet, I never knew this is a completely different technology which is not based on logins and I have never been prompted by any popup RED BIG saying: please save your wallet etc.!!! so, the questions is, what now? I just lost a few thousands ethereum?? Sigh, what a joke. When I used geth in February 2016, there was no mention that the software would put a private key in some random folder on my computer, while also downloading the entire ethereum blockchain. Well no duh I decided to delete a 10gig + folder on my hard drive when I needed space and was not an ethereum miner. All it said was to guard the password with my life. No mention to guard the private key with your life. No mention of putting super important files in a completely random directory. When people like myself or others are trying to promote Ethereum, we lose all our eth due to terrible documenta Continue reading >>

On Mist, Can I Create A .json File Wallet Protected By A Password (or Not) Just Like Ethereumwallet?

On Mist, Can I Create A .json File Wallet Protected By A Password (or Not) Just Like Ethereumwallet?

On Mist, can I create a .json file wallet protected by a password (or not) just like ethereumwallet? The key file is called web3 secret storage (and version 3 is used today). This format makes a password mandatory, but doesn't put a restriction on the password length. It can be zero. Or could be something really long. There are various tools (wallets), which can export a V3 file. ethereumwallet.com (and I think myethereumwallet too) will use an empty password ('') for the unencrypted wallets. On my local geth I've hit enter on both password fields and got a file with password of '': $ geth account newYour new account is locked with a password. Please give a password. Do not forget this password.Passphrase:Repeat Passphrase: Note: even with this, the file is still encrypted, albeit with the empty password. You need to remember it uses the empty password. Mist is actually a browser. It is meant to be used to browse decentralized applications in the future. During the development process it only supports one DApp: the Ethereum Wallet DApp. see: github/ethereum/mist Ethereum Wallet DApp: Is the wallet software you refer to when saying "mist". That's okay, because it currently really almost is the same. The wallet DApp runs inside mist. see: github/ethereum/meteor-dapp-wallet Both mist and the wallet require a client (ethereum node) in the backend which could either be geth or eth (or really any other ethereum client). Currently, the mist browser includes all of them: mist browser, dapp wallet and a client for the backend. see: github/ethereum/go-ethereum for geth and github/ethereum/webthree-umbrella for eth. Now that you understand that not Mist is the wallet, but the DApp provides the wallet functionality on top of (probably) geth, you can simply use the JSON-RPC API, th Continue reading >>

Electrum Bitcoin Wallets Were Vulnerable To Hackers For Two Years

Electrum Bitcoin Wallets Were Vulnerable To Hackers For Two Years

Electrum Bitcoin Wallets Were Vulnerable to Hackers for Two Years Developers left the vulnerability unpatched for months after being alerted. For almost two years, hackers could have easily stolen your prized stash of bitcoins if you were keeping them in the popular software wallet Electrum, thanks to a critical security vulnerability that went unpatched until now. The vulnerability allowed any website (and anyone controlling the site a victim browsed, like a hacker) to steal bitcoins stored using Electrum, as long as the software was running and there was no encryption password set up, according to security researchers. The bug was initially reported by Github user jsmad on November 24, 2017. Electrum, however, didnt fully patch the bug until Sunday, January 7, and only after Google security researcher alerted them to how serious the bug really was. The bitcoin wallet Electrum allows any website to steal your Bitcoins, Ormandy tweeted on Saturday. I was gonna report it but there was already an open issue from last year. I pointed out this is kinda critical, and they made a new release within a few hours. Read more: The Motherboard Guide To Not Getting Hacked Mustafa Al-Bassam , a postgraduate researcher at University College London, told me over Twitter that the hackers could have exploited the bug since February 2016, almost two years ago, when developers released Electrum 2.6. [The bug] allows any malicious website to control your Electrum wallet, including stealing all your Bitcoin if the wallet isn't encrypted with a password, Al-Bassam told me via Twitter direct message. Even if the wallet does have a password, he explained, a hacker could still redirect bitcoins from the wallet to their address. An initial patch for the bug was released on Saturday, but confusio Continue reading >>
