For a given private key, pr, the Ethereum address A (pr) (a 160-bit value) to which it corresponds is defined as the right most 160-bits of the Keccak hash of the corresponding ECDSA public key. To generate Ethereum address, take Keccak-256 hash of public key. Right most 20 bytes is your Ethereum address.The private key must be 32 bytes and not begin with 0x00 and the public one must be uncompressed and 64 bytes long or 65 with the constant 0x04 prefix. More on that in the next section.
