Struct ed25519_dalek::SecretKey

pub struct SecretKey(pub [u8; 64]);

An ed25519 private key.

Methods

impl SecretKey

fn to_bytes(&self) -> [u8; 64]

View this secret key as an array of 32 bytes.

fn from_bytes(bytes: &[u8]) -> SecretKey

Construct a SecretKey from a slice of bytes.

Warning

The caller is responsible for ensuring that the bytes represent a masked secret key. If you do not understand what this means, DO NOT USE THIS CONSTRUCTOR.
