/**
 * PublicKeyInfo
 *
 * PublicKeyInfo and SubjectPublicKeyInfo are pretty much the same. the only difference
 * is that in SubjectPublicKeyInfo (which actually is defined by an RFC - RFC5280) the
 * element names are algorithm and subjectPublicKey whereas in this one they're
 * publicKeyAlgorithm and publicKey. the publicKey bit, in particular, is relevant, because
 * publicKey is also an optional element in OneAsymmetricKey and it just makes life easier
 * to do isset($key['publicKey']) irrespective of which "map" was used to load the key.
 *
 * PublicKeyInfo::MAP is only used in PKCS8.php and it's children classes
 *
 * PHP version 8.1+
