Struct Ed25519Signer 

pub struct Ed25519Signer { /* private fields */ }

Signs records with an Ed25519 key the host supplies. Key generation and storage are host concerns; the crate only consumes the 32 secret bytes.

Implementations

impl Ed25519Signer

pub fn from_secret_bytes(secret: &[u8; 32]) -> Self

pub fn public_key(&self) -> PublicKeyBytes

The signer’s public key bytes.

pub fn public_key_hex(&self) -> String

The signer’s public key as lowercase hex - the Signature.key_id this signer produces.

pub fn sign(&self, record: &Record) -> Result<Signature, Error>
