the class X509TestHelpers method newSelfSignedCACert.

/**
 * Uses the private key of the given key pair to create a self-signed CA certificate with the public half of the
 * key pair and the given subject and expiration. The issuer of the new cert will be equal to the subject.
 * Returns the new certificate.
 * The returned certificate should be used as the trust store. The private key of the input key pair should be
 * used to sign certificates that are used by test peers to establish TLS connections to each other.
 * @param subject the subject of the new certificate being created.
 * @param keyPair the key pair to use. The public key will be embedded in the new certificate, and the private key
 *                will be used to self-sign the certificate.
 * @param expirationMillis expiration of the new certificate, in milliseconds from now.
 * @return a new self-signed CA certificate.
 * @throws IOException
