Struct Ed25519PrivKey

pub struct Ed25519PrivKey { /* private fields */ }

An Ed25519 private key.

An Ed25519PrivKey actually includes both the private key and the public key in order to make multiple key signing operations with the same key more efficient.

Implementations

impl Ed25519PrivKey

pub fn generate() -> Ed25519PrivKey

Generates a new private key.

pub fn from_key_pair_bytes( private: [u8; 32], public: &Ed25519PubKey, ) -> Ed25519PrivKey

Constructs a new private key from a key pair.

Usually, an Ed25519 private key will be stored as a single 64-byte blob: the 32-byte private key followed by the 32-byte public key. However, we accept the two keys as separate arguments in case they are stored separately.

pub fn from_private_key_bytes(private: [u8; 32]) -> Ed25519PrivKey

Constructs a new private key.

Unlike from_key_pair_bytes, from_private_key_bytes reconstructs the key (which includes both the private key and the public key internally) from only the private key.

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

Gets the raw bytes of the private key.

fn public(&self) -> Ed25519PubKey

Gets the public key corresponding to this private key.
