raw property

@override Uint8List get raw

Returns the key's raw bytes

Implementation

@override
Uint8List get raw {
  try {
    // Get the private value
    final d = _key.d!;

    // Get the public key point
    final q = _publicKey._key.Q!;

    // Create a simple ASN.1 sequence with the private value and public key coordinates
    final asn1Sequence = pc.ASN1Sequence();
    asn1Sequence.add(pc.ASN1Integer(d));
    asn1Sequence.add(pc.ASN1Integer(q.x!.toBigInteger()!));
    asn1Sequence.add(pc.ASN1Integer(q.y!.toBigInteger()!));

    return Uint8List.fromList(asn1Sequence.encode());
  } catch (e) {
    throw ECDSAKeyException('Failed to encode ECDSA private key: ${e.toString()}');
  }
}
