        buf: &mut [u8],

}

A stateless (oneshot) signature interface

Required Methods

fn info(&self) -> SignerInfo

Returns information about the signer

fn sign( &self, buf: &mut [u8], data: &[u8], sec_key: &[u8], ) -> Result<usize, Box<dyn Error + 'static>>

Signs data into buf using sec_key and returns the signature length

fn verify( &self, data: &[u8], sig: &[u8], pub_key: &[u8], ) -> Result<(), Box<dyn Error + 'static>>

Verifies sig for data with pub_key and returns an error if the signature was invalid
