Checks whether this certificate was potentially issued by the given otherCert by comparing the certificate metadata.
This is useful for pruning a list of possible issuer certificates which have been selected using a more rudimentary filtering routine, i.e. just based on subject and issuer names.
Finally, to verify that this certificate's signature was produced by a private key corresponding to otherCert's public key use x509.verify(publicKey) with otherCert's public key represented as a KeyObject like so
if (!x509.verify(otherCert.publicKey)) {
throw new Error('otherCert did not issue x509');
}
