I сreated a library for bitcoin address generation from xpub. After installation you can write:
An Xpub key can be broken into 2 parts.
The first 32 bytes, is the key and the last 32 bytes is the chaincode.
You can use the key part to create addresses by hashing it with
ripemd160(sha256(key))and then encoding the resulting 20 byte hash with Base58 for legacy P2PKH addresses or Bech32 for Segwit P2WPKH addresses.
