Crate seed_utils

seed-utils

Note: The word seed is interchangeably used for bip39 mnemonics.

• Derive bip85 child seeds
• Derive bip32 root xpubs and xprvs from seeds
• Derive account xpubs and xprvs
• XOR seeds
• Truncate (reduce entropy to keep first n words of a seed)
• Extend (extend entropy to add words to a seed)

All errors in this crate.

WordCount

Valid number of words in a mnemonic.

Functions

derive_child_seeds

Derives child seeds of seed with an index range of [start, end). Each seed’s word count will be exactly word_count. Returns list of tuples containing the derived seeds and their indexes.

derive_root_xprv

Derives the master private key of a seed at the bip32 root.

derive_root_xpub

Derives the master public key of a seed at the bip32 root.

derive_xprvs_from_seed

Derives account extended private keys of a seed with an index range [start, end) and the derivation path of version. Returns a tuple of the derivation path and its derived xprv.

derive_xpubs_from_seed

Derives account extended public keys of a seed with an index range [start, end) and the derivation path of version. Returns a tuple of the derivation path and its derived xpub.

extend_seed

Extends a seed’s number of words to the desired length word_count by enxtending its entropy. The returned new seed will start with the same words as seed.

truncate_seed

Truncates a seed’s number of words to word_count by truncating its entropy.

xor_seeds

XORs multiple seeds and returns the resulting seed or None if seeds is empty. Can fail if a seed is not a valid [bip39::Mnemonic].
