Parsing Master List with Spongy castle return Null Public Key

[nadine199177]

I am trying to parse the master list using the code below in this link:

Github MasterList Parser

Using this code (Bouncy Castle) I am getting the error below:

        try {
            Enumeration<?> derObjects = ASN1Sequence.getInstance(octets).getObjects();
            CertificateFactory cf = CertificateFactory.getInstance("X.509","BC");

            while (derObjects.hasMoreElements()) {
                ASN1Integer version = (ASN1Integer)derObjects.nextElement(); //Should be 0
//              if (version!=0) throw Exception; //TODO Exception model
                ASN1Set certSet = ASN1Set.getInstance(derObjects.nextElement());

                Enumeration<Certificate> certs = certSet.getObjects();
                while (certs.hasMoreElements()) {
                    org.bouncycastle.asn1.x509.Certificate certAsASN1Object = org.bouncycastle.asn1.x509.Certificate.getInstance(certs.nextElement());
                    cscaCerts.add(cf.generateCertificate(new ByteArrayInputStream(certAsASN1Object.getEncoded())));
                }

            }
java.security.NoSuchAlgorithmException: The BC provider no longer provides an implementation for CertificateFactory.X.509. Please see https://android-developers.googleblog.com/2018/03/cryptography-changes-in-android-p.html for more details.

Using Spongy Castle I am getting null in public key (in object java.security.cert within the list cscaCerts) NO error but after parsing null public key presented.

  try {
            Enumeration<?> derObjects = ASN1Sequence.getInstance(octets).getObjects();

            while (derObjects.hasMoreElements()) {
                ASN1Integer version = (ASN1Integer) derObjects.nextElement(); //Should be 0
//              if (version!=0) throw Exception; //TODO Exception model
                ASN1Set certSet = ASN1Set.getInstance(derObjects.nextElement());

                Enumeration<Certificate> certs = certSet.getObjects();
                while (certs.hasMoreElements()) {
                    org.spongycastle.asn1.x509.Certificate certAsASN1Object = org.spongycastle.asn1.x509.Certificate.getInstance(certs.nextElement());
                    cscaCerts.add(new X509CertificateObject(certAsASN1Object));
                }

            }
