Expand description

Combination of DigestSigner and RandomizedSigner with support for computing a signature over a digest which requires entropy from an RNG.

Required Methods§

source

fn try_sign_digest_with_rng( &self, rng: impl CryptoRng + RngCore, digest: D ) -> Result<S, Error>

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

Provided Methods§

source

fn sign_digest_with_rng(&self, rng: impl CryptoRng + RngCore, digest: D) -> S

Sign the given prehashed message Digest, returning a signature.

Panics in the event of a signing error.
