# How To Get Public Key From Ethereum Address

When you want to send someone ether, you need their public key so that you can direct the ether to them. You can find someone’s public key by looking up their address on a blockchain explorer.

Once you have the public key, you can send ether to them by entering the following command into the console in your Ethereum wallet:

“sendtoaddress “public key” “ether amount””

For example, if I wanted to send 0.1 ether to someone with the public key “0x12345678901234567890”, I would enter the following command:

“sendtoaddress 0x12345678901234567890 0.1”

If you want to send tokens instead of ether, you can use the “transfer” command instead of “sendtoaddress”.

## How do I find my ETH public key?

When you want to use your Ethereum address to receive payments or interact with the Ethereum network, you will need to know your public key. This article will show you how to find it.

To find your public key, you will need to first find your Ethereum address. To do this, open up your Ethereum wallet and go to the “Receive” tab. Your address will be displayed in the “Address” field.

Once you have your address, you can find your public key by going to the “Addresses” tab and clicking on the address you want to view. Your public key will be displayed in the “Public key” field.

## Can you get the public key from an Ethereum address?

Can you get the public key from an Ethereum address?

Yes, it is possible to get the public key from an Ethereum address. However, it is not always easy to do so. There are a few different ways to get the public key from an Ethereum address, but each method has its own set of pros and cons.

One way to get the public key from an Ethereum address is to use the geth console. This method is easy to use, but it can be time-consuming if the address is large. Another way to get the public key from an Ethereum address is to use a third-party website or tool. This method is fast and easy, but it can be risky if the website or tool is not trustworthy.

Ultimately, the best way to get the public key from an Ethereum address depends on the individual situation. However, all of the methods mentioned above are viable options.

## Can you derive public key from address?

Can you derive public key from address?

Yes, you can. The public key can be derived from the address using a process called Elliptic Curve Cryptography (ECC). ECC is a type of cryptography that uses mathematical algorithms to secure data.

## How do I get the public key from Ethereum transaction?

When you send a transaction on the Ethereum blockchain, you are essentially signing it with your private key. This signature is used to verify that the transaction came from you. The public key is used to determine the recipient of the transaction.

To get the public key from an Ethereum transaction, you can use the getTransactionInputs() function. This function will return an array of objects, each of which contains the public key, the transaction hash, and the input index.

Here is an example of how to use the getTransactionInputs() function:

var transactionInputs = eth.getTransactionInputs(txHash);

var publicKeys = [];

for (var i = 0; i < transactionInputs.length; i++) {

publicKeys.push(transactionInputs[i].publicKey);

}

You can then use the public keys to determine the recipient of the transaction.

## How do I find the public key for an address?

When you want to send someone cryptocurrency, you need their public key to do so. This article will teach you how to find it.

To locate someone’s public key, you can use a blockchain explorer such as Blockchain.info. Simply enter the person’s bitcoin address into the search bar, and the explorer will return the public key associated with that address.

Another way to find someone’s public key is to use a site like Bitcoin Block Explorer. Simply enter the person’s name or email address into the search bar, and the site will return a list of addresses associated with that name or email address. Click on one of the addresses to see the corresponding public key.

If you want to send someone a message, you can use a site like Bitmessage. Simply enter the person’s Bitmessage address into the search bar, and the site will return the public key associated with that address.

Now that you know how to find someone’s public key, you can go ahead and send them cryptocurrency!

## Is public key the same as address?

When you create a cryptocurrency wallet, you are given a public key and a private key. The public key is used to receive payments, while the private key is used to sign payments. Many people mistakenly believe that the public key and address are the same thing. However, this is not the case.

The public key is a long, alphanumeric string that is used to identify your wallet. The address is the shortened, human-readable version of the public key. It is generated when the public key is encrypted using a hashing algorithm.

The address is used to receive payments, but it is not the only way to send payments. You can also send payments by using the public key. This is done by encrypting the payment with the recipient’s public key and then sending it to their address.

It is important to remember that the public key and the address are not the same thing. The public key is used to receive payments, while the address is used to send payments.

## How do I generate my public key?

To generate a public key, you will first need to create a key pair. This is done by running the following command in a terminal:

openssl genrsa -out mykey.key 2048

This will create a file called “mykey.key” in the current directory. This is your private key.

Next, you need to generate a public key. This can be done by running the following command:

openssl rsa -in mykey.key -pubout -out mykey.pub

This will create a file called “mykey.pub” in the current directory. This is your public key.
