Struct SpendKey

Source 
pub struct SpendKey { /* private fields */ }
Expand description

A key representing a single spending authority.

Implementations§

Source§

impl SpendKey

Source

pub fn to_bytes(&self) -> SpendKeyBytes

Get the SpendKeyBytes this SpendKey was derived from.

This is useful for serialization.

Source

pub fn from_seed_phrase_bip39(seed_phrase: SeedPhrase, index: u64) -> Self

Deterministically generate a SpendKey from a SeedPhrase.

The choice of KDF (PBKDF2), iteration count, and PRF (HMAC-SHA512) are specified in BIP39. The salt is specified in BIP39 as the string “mnemonic” plus an optional passphrase, which we set to an index. This allows us to derive multiple spend authorities from a single seed phrase.
