int bip85_get_bip39_entropy(const struct ext_key *hdkey, const char *lang, uint32_t num_words, uint32_t index, unsigned char *bytes_out, size_t len, size_t *written)

Generate bip39 mnemonic entropy according to bip85.

Parameters:

  • hdkey – The parent extended key to derive entropy from.

  • lang – The intended language. Pass NULL to use the default English value.

  • num_words – The intended number of words. Must be 12, 18 or 24.

  • index – The index used to create the entropy. Must be less than BIP32_INITIAL_HARDENED_CHILD.

  • bytes_out – Where to store the resulting entropy.

  • len – Size of bytes_out. Passing HMAC_SHA512_LEN will ensure the buffer is large enough.

  • written – Number of bytes in bytes_out to be used as entropy.

Returns:
