Expand description

Trait impl’d by public / private keypairs that can generate recoverable signatures

Required Associated Types§

Source

type PubKey

Source

type Sig: RecoverableSignature<Signer = Self, PubKey = Self::PubKey>

Required Methods§

Source

fn sign_recoverable_with_hash<H: HashFunction<32>>( &self, msg: &[u8], ) -> Self::Sig

Sign as a recoverable signature using the given hash function.

Note: This is currently only used for Secp256r1 and Secp256k1 where the hash function must have 32 byte output.

Provided Methods§

Source

fn sign_recoverable(&self, msg: &[u8]) -> Self::Sig

Sign as a recoverable 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.
