Struct iop_keyvault::Seed

pub struct Seed { /* private fields */ }

The seed used for BIP32 derivations. A seed cannot be turned back into a phrase, because there is salted hashing involed in creating it from the BIP39 mnemonic phrase.

Implementations

impl Seed

pub const BITS: usize = 512usize

Number of bits in entropy generated from the bip39 mnemonic

pub const DEMO_PHRASE: &'static str = "include pear escape sail spy orange cute despair witness trouble sleep torch wire burst unable brass expose fiction drift clock duck oxygen aerobic already"

A BIP39 phrase we use in most of the demo videos and proof-of-concept applications. Do not use it in production code.

pub const PASSWORD: &'static str = "morpheus"

Legacy password used in the 0.0.1 version of the crate. Since 0.0.2 the crate always requires a password, which should be “” by default when the user does not provide one.

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Creates seed from a raw 512-bit binary seed

Example

let bytes = "86f07ba8b38f3de2080912569a07b21ca4ae2275bc305a14ff928c7dc5407f32a1a3a26d4e2c4d9d5e434209c1db3578d94402cf313f3546344d0e4661c9f8d9";
let seed_res = Seed::from_bytes(hex::decode(bytes).unwrap().as_slice());
assert!(seed_res.is_ok());

pub fn as_bytes(&self) -> &[u8]

Returns the bytes of the seed
