 * @param subject   The request's subjectDN
 * @param publickey the public key for the certificate requesting signing
 * @param attributes    A set of attributes, for example, extensions, challenge password, etc.
 * @param privateKey the private key used to generate the certificate
 * @param provider
 * @return a PKCS10CertificateRequest based on the input parameters.

 * @throws OperatorCreationException if an error occurred while creating the signing key
