BIP-32 extended key (xpub, xprv)
ID bip32addr
DatatypeNot PIIidentifier
Extended public or private key of a hierarchical deterministic (HD) wallet in the serialization of BIP-32: 4 version bytes, depth, fingerprint of the parent key, child number, 32-byte chain code and 33-byte key data, followed by a 4-byte checksum and encoded with Base58Check into 111 characters. Mainnet keys start with xpub (public) or xprv (private), testnet keys with tpub or tprv. An xprv value is a wallet secret that controls all funds below it; an xpub value reveals every address of its branch. Keys with the prefixes of SLIP-132 (ypub, zpub and others) use the same structure but are not matched here.
