Trait ed25519_dalek::Signer[][src]

pub trait Signer<S> where
    S: Signature
{ fn try_sign(&self, msg: &[u8]) -> Result<S, Error>; fn sign(&self, msg: &[u8]) -> S { ... } }
Expand description

Sign the provided message bytestring using Self (e.g. a cryptographic key or connection to an HSM), returning a digital signature.

Required methods

fn try_sign(&self, msg: &[u8]) -> Result<S, Error>[src]

Expand description

Attempt to sign the given message, returning a digital signature on success, or an error if something went wrong.

The main intended use case for signing errors is when communicating with external signers, e.g. cloud KMS, HSMs, or other hardware tokens.
