Private key

5 stars based on 50 reviews

Before we get deeper into ethereum secret key concept of Ethereum Blockchainit is important to understand how Public Key, Private Key and Address are generated.

To make this easier for beginners, I am trying to explain the technical concept with an example. Ethereum key generation is based ethereum secret key elliptical curve ecpk1.

Eliptical curve EC is intense mathematics, and there are a lot of great articles on internet covering deep details of elliptical curve. There are standard libraries to generate Ethereum key pair in much safer way.

In this article, just for demonstration, I will use elliptical curve Javascript libaray to perform elliptical curve operations. A good library generate a private key with taking sufficient randomness into account.

For this exercise we will take "1" as private key which is an acceptable private key because it lies in specified range mentioned above. Ethereum requires private key to be bit long. Here is ethereum secret key sample code for nodejs. This is done using group operation of EC cryptography. To derive public key, ethereum secret key key is multiplied by G. Multiplication used to derive public is EC multiplication which is entirely different from normal multiplication for which I am going to use JS library.

G is ethereum secret key generator point which is one of the domain parameters of EC cryptography. G has fixed value for ecpk1, which is recommended by experts.

For a given private key, pr, the Ethereum address A pr a bit value to which it corresponds is defined as the right most bits of the Keccak hash of the corresponding ECDSA public key. To generate Ethereum address, take Keccak hash of public key.

Right most 20 bytes is your Ethereum address. This is just an example to understand the concept. Please do not use it to generate real wallet to hold ETH. You can also reach us at contact etherworld.

I don't think anyone uses the ethereum wallet. It looks like you're new here. If you want to get involved, click one of these buttons! April in Protocol and Client discussion. Hi, is it possible to see your accounts private key from the wallet?

I see links to websites like; http: But there obviously got to be a way to see it from the keystore file? I opened my keystore file with notepad and found some info there. Is The private key obtainable from notepad? Sorry for the noob question, been using exchanges only for two years.

Do you mean the Ethereum Wallet. It simply looks to your keystore when you need to transact. Vapro You said you've opened your keystore file. What are you actually wanting to see? You can't see the EC private key code itself because it's encrypted. That's the whole point. What you see in that file is the public address and the encryption data generated when you first created the wallet and gave it a password.

GG , People come because they have question. Regardless of their experience isn't it simply better to help them by answering their questions instead of making base assumptions upon their needs and personal capabilities?

This stuff is still hard. There's no shame in not understanding what it is and how to use it. In some not so distance future it will be a lot easier. But until then lets just use what we've got to help whoever comes along. GG , I explained to the OP the contents of the keystore file he was looking at. The file itself IS his private key but just not in a format he seemed to be expecting.

How's that not a helpful answer? The wallet only needs the following: Just like a bank, Your account info Your passcode Your identification, just in case you lose your passcode And no blockchain syncing Just start syncing from the last block The simpler, the better. Ian O'Neill Member Posts: I too am wondering about my private key in my ethereum wallet - how do I access it?

Can anyone else access it? Is the ethereum wallet secure? As a non programmer occasionally executing my first transactions in crypto in recent weeks, there are a myriad of concerns that come to mind - password protection, private key protection, hacking concerns, etc. I start calling friends for help - friends in the know i. But we know that, don't we? So my question still is how do I know what my private key is in my ethereum wallet dag nannit?

OK, here is the answer to the question 'how do you see my private key' which I got from a trusted source in the crypto space: Finally he also said you must backup your files: To backup the private key and account details.

This required to be done once only and not every time you send or receive Ether. These can used to restore anytime by copying to the corresponding. Sign In or Register to comment.
