Expand description

Sign the given message using the provided external randomness source.

Required Methods§

Source

fn try_sign_with_rng<R>(&self, rng: &mut R, msg: &[u8]) -> Result<S, Error>
where R: TryCryptoRng + ?Sized,

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.

§Errors

Returns implementation-specific errors in the event signing failed (e.g. KMS or HSM communication error), or if the provided rng experiences an internal failure.
