Notation: P1 and P2 are valid, serialized, public keys. S1 and S2 are valid signatures using respective keys P1 and P2. S1' and S2' are non-DER but otherwise valid signatures using those same keys. F is any invalid but DER-compliant signature (including 0, the empty string). F' is any invalid and non-DER-compliant signature.
