They must remain secret at all times to prevent unauthorized access or theft of your Bitcoins. The checksum is derived from the hash of the encoded data and can therefore be used to detect and prevent transcription and typing errors. So if you use an HD wallet, each transaction will use a new private-public key pair and derive an address. Brainwallet: This tool allows users to create a new wallet address and corresponding private key based on a passphrase or set of words.

So why keep Y? Now we need to calculate the checksum of our mainnet key.
