将X509CertificateHolder对象转换为X509certificate时出现以下异常

Question

主题公开密钥信息：

            Public Key Algorithm: id-ecPublicKey
            Unable to load Public Key

删除setprovider（“ BC”）后，仅在Q cookie中发生此错误 从下面的代码：

 X509Certificate  x509object= new JcaX509CertificateConverter().setProvider("BC")
                                .getCertificate(x509certificateHolder);

cert = (X509CertificateHolder)certIt.next();
 signerX509Certificate = new JcaX509CertificateConverter()
                                .getCertificate(cert)
