Trait RandomizedSigner

Source 
pub trait RandomizedSigner<S: Signature> {
    // Required method
    fn try_sign_with_rng(
        &self,
        rng: impl CryptoRng + RngCore,
        msg: &[u8],
    ) -> Result<S, Error>;

    // Provided method
    fn sign_with_rng(&self, rng: impl CryptoRng + RngCore, msg: &[u8]) -> S { ... }
}
Expand description

Sign the given message using the provided external randomness source.

Required Methods§

Source

fn try_sign_with_rng( &self, rng: impl CryptoRng + RngCore, 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

fn sign_with_rng(&self, rng: impl CryptoRng + RngCore, 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.
