Examples with Asn1Sequence de.rub.nds.asn1.model.Asn1Sequence used on opensource projects

Example 1 with Asn1Sequence

use of de.rub.nds.asn1.model.Asn1Sequence in project TLS-Scanner by tls-attacker.

the class OcspProbe method prepareNonceExtension.

private byte[] prepareNonceExtension() {
    Asn1Sequence innerExtensionSequence = new Asn1Sequence();
    Asn1ObjectIdentifier oid = new Asn1ObjectIdentifier();
    oid.setValue(NONCE.getOID());
    Asn1Sequence extensionSequence = new Asn1Sequence();
    innerExtensionSequence.addChild(oid);
    Asn1EncapsulatingOctetString encapsulatingOctetString = new Asn1EncapsulatingOctetString();
    // Nonce
    Asn1PrimitiveOctetString nonceOctetString = new Asn1PrimitiveOctetString();
    Random rand = new Random(STAPLED_NONCE_RANDOM_SEED);
    BigInteger nonce = new BigInteger(STAPLED_NONCE_RANDOM_BIT_LENGTH, rand);
    nonceOctetString.setValue(nonce.toByteArray());
    encapsulatingOctetString.addChild(nonceOctetString);
    innerExtensionSequence.addChild(encapsulatingOctetString);
    extensionSequence.addChild(innerExtensionSequence);
    List<Asn1Encodable> asn1Encodables = new LinkedList<>();
    asn1Encodables.add(extensionSequence);
    Asn1Encoder asn1Encoder = new Asn1Encoder(asn1Encodables);
    return asn1Encoder.encode();
}
