- openssl's ecdsa verify() will produce a bool, not a result. hence we need to verify the result. - the verify() requires a sha384 (SEV-SNP ABI spec, ch10) encoded report body, not the raw bytes - add test cases for both successful and failed signature verification Signed-off-by: Magnus Kulke <[email protected]>
