Creating and managing your keys

In Ethereum, a public key is a string of letters and numbers that represents a user’s address on the Ethereum blockchain. Public keys are derived from private keys, which are also a string of letters and numbers, but they are meant to be kept secret.

A public key is used for the following:

• Receiving Ether or other tokens on the Ethereum network: Other users can send Ether or tokens to a user’s public key address
• Verifying the identity of a user when they sign a transaction: By using the corresponding private key, a user can sign a message to prove that they own the associated public key
• Deriving public keys from private keys using a one-way cryptographic function called a hash function: This ensures that it is computationally infeasible to determine a private key from a public key, making it safe to share a public key with others

It is important to note that Ethereum public keys are different from the public keys...
