Function evercrypt::signature::sign

pub fn sign<'a>(
    mode: Mode, 
    hash: impl Into<Option<Mode>>, 
    sk: &[u8], 
    msg: &[u8], 
    nonce: impl Into<Option<&'a Nonce>>
) -> Result<Vec<u8>, Error>

Sign a message msg with the secret key sk and the given signature scheme (mode). For ECDSA the hash algorithm and a nonce have to be passed in as well.
