}

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
