// Tests for CVE-2022-21449
// https://neilmadden.blog/2022/04/19/psychic-signatures-in-java/
// Dubbed "Psychic Signatures", these signatures bypassed the ECDSA signature
// verification implementation in Java in 15, 16, 17, and 18. OpenSSL is not
// (and was not) vulnerable so these are a precaution.
