========================
Pure functions reference
========================

Base function primitives implemented in functional programming paradigm.



Mnemonic(BIP39)
===============

.. autofunction:: pybtc.generate_entropy
.. autofunction:: pybtc.load_word_list
.. autofunction:: pybtc.entropy_to_mnemonic
.. autofunction:: pybtc.mnemonic_to_entropy
.. autofunction:: pybtc.mnemonic_to_seed


Private keys
============

.. autofunction:: pybtc.create_private_key
.. autofunction:: pybtc.private_key_to_wif
.. autofunction:: pybtc.wif_to_private_key
.. autofunction:: pybtc.is_wif_valid


Public keys
===========

.. WARNING::
   Using uncompressed public keys is
   `deprecated <https://github.com/bitcoin/bips/blob/master/bip-0143.mediawiki#restrictions-on-public-key-type>`_
   in  a new SEGWIT address format.
   To avoid potential future funds loss, users MUST NOT use uncompressed keys
   in version 0 witness programs. Use uncompressed keys only for backward
   compatibilitylegacy in legacy address format (PUBKEY, P2PKH).
