Available on crate feature rand_core only.
Expand description

Sign the given message using the provided external randomness source.

Required Methods§

Source

async fn try_sign_with_rng_async( &self, rng: &mut impl CryptoRngCore, msg: &[u8], ) -> Result<S, Error>

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.

Provided Methods§

Source

async fn sign_with_rng_async( &self, rng: &mut impl CryptoRngCore, msg: &[u8], ) -> S

Sign the given message and return a digital signature

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
