Bip39’s entropy to mnemonic http://www.video-bookmark.com/user/tucanewhmt Checksum generation: A checksum is created from this entropy using SHA-256 hashing, which aids validate the mnemonic's integrity later. Due to the cryptographic design and style of BIP-39, a weak passphrase doesn't lessen the security of another wallets or help expose the seed words.
