Implmenet PublicKeyInfo

[SmartLayer]

It's used in SignedDevconTicket.

While PublicKeyInfo is still useful (in IdentifierAttestation I suppose), I'm making the argument of not including it in SignedDevconTicket (the one that should be delivered by the end of 2020 but haven't due to refactoring of the ASN schema).

@jot2re decided to keep PublicKeyInfo optional instead of dropping it, so this issue can continue now.

Hi Weiwu,

I have completed the extracting PublicKeyInfo from the DER encoded data in SignedDevconTicket. Also added a test case in ParserSerializerTest.js.

Test Case:

// get PublicKeyInfo
const derpk = readFileSync('build/test-results/signed-devcon-ticket-with-pk.der');
let dataobj2 =  new SignedDevconTicket(new Uint8Array(derpk).buffer);
console.log(dataobj2);

Result:

SignedDevconTicket {
  ticket: DevconTicket {
    devconId: ArrayBuffer { [Uint8Contents]: <06>, byteLength: 1 },
    ticketId: ArrayBuffer { [Uint8Contents]: <00 be 06>, byteLength: 3 },
    ticketClass: ArrayBuffer { [Uint8Contents]: <00>, byteLength: 1 }
  },
  commitment: ArrayBuffer {
    [Uint8Contents]: <04 20 64 30 ca e2 02 e5 fa b4 1c e5 4b 74 72 5e 45 4f f8 08 72 0a 03 90 37 d8 40 3d 95 fe fd c0 35 12 2c 95 bf d2 ae 1a 48 a3 f4 2f

    byteLength: 65
  },
  publicKeyInfo: PublicKeyInfo {
    algorithm: AlgorithmIdentifier {
      algorithmId: '1.2.840.10045.2.1',
      algorithmParams: [Sequence]
    },
    subjectPublicKey: BitString {
      blockLength: 68,
      error: '',
      warnings: [],
      valueBeforeDecode: [ArrayBuffer],
      idBlock: [LocalIdentificationBlock],
      lenBlock: [LocalLengthBlock],
      valueBlock: [LocalBitStringValueBlock]
    }
  },
  signatureValue: ArrayBuffer {
    [Uint8Contents]: <30 44 02 20 38 db 21 b6 b5 b7 c6 92 da ad a2 b6 2e bb 89 e5 a3 6e 3a 3c ce 66 1e 38 53 2b c9 ac c8 5c 34 1b 02 20 70 46 73 21 8f 77

    byteLength: 70
  }
}

The related code is pushed in branch - asn1js-parser-serializer

@jot2re his work can be verified by running

$ gradle test
$ gradle testJavaScript

I'll attempt to add some integration test on top of it so the DER from java is parsed by JavaScript then the other way too.

[jot2re]

All the tests seem to pass on my machine. @darakhbharat is this ready for review?

Yes. I mean:

#75 - Decoding PublicKeyInfo from the DER data is completed. #65 - Implemented serialize method which creates exactly same DER data when decoded to object from the existing DER file and serialize it to new file. - JS serialize using instantiating the dictionary object is not completed yet.
