Python implementation of Bitcoin hierarchical deterministic wallet

The bip32utils library is a pure Python implementation of Bitcoin hierarchical deterministic wallet ("HD Wallet") ECDSA key generation as specified in BIP0032 (Bitcoin Improvement Proposal #0032).

Deterministic ECDSA key generation allows creating a sequence of Bitcoin private and public ECDSA keys from an initial seed and a hierarchical set of indices. A number of benefits follow:

 - An entire wallet can be backed up once by storing the wallet seed or master
   extended private key, and all future addresses in the wallet can be restored
   from it.
 - The creation of public and private ECDSA keys may be separated from each
   other. That is, it is possible to create only the public ECDSA key half
   (and receiving address) of an ECDSA key pair, without the ability to create
   the private half. Thus, one can create receiving addresses on a public
   facing system that if compromised would not give the attacker the ability to
   spend bitcoin received at those addresses. A separate, offline machine can
   generate the corresponding private ECDSA keys and sign transactions.
 - Public and private ECDSA keys may be created in a hierarchy, and control
   over or visibility of portions of the hierarchy may be delegated to third
   parties.
   This has uses for auditing, for separating ECDSA key sequences into
   different logical groups or accounts, and for giving 3rd parties the ability
   to create spending transactions without first getting a receiving address
   in advance.
