BIP39 (mnemonic)

This is a pure v-lang implementation of BIP39.

WARNING: seed generation is not supported yet, only mnemonic to entropy and vice-versa is supported.

Wordlists

Only English is supported right now and is embeded on compile time. Wordlist comes from official bitcoin/bip-0039/english.txt.

Mnemonic

The module needs to be instanciated with:

m := mnemonic.new()!

Possible error are wordlist parsing issue.

Get entropy from mnemonic

words := "winter hire open opinion frown turtle this bulb mouse spell endorse thumb regret useless expand nerve improve impulse"
entropy := m.to_entropy(words)

Get mnemonic from entropy

entropy := m.generate_entropy(224)! // or your own entropy buffer
words := m.to_mnemonic(entropy)!

Tests

In order to validate implementation, tests vector from python-mnemonicvectors.json is included.

This is implemented via mnemonic_test.v
