Quick reference card: Private keys and addresses
An Ethereum address is derived from the last 20 bytes of the Keccak-256 hash of the public key. It is written as 0x followed by 40 hexadecimal characters.
Avoid exporting your private key unless necessary. If you absolutely must, don't copy it into an online notes app.
