Quick Note on Javacard: Episode 2

EAID Scheme


AID Scheme:
5 bytes RID + 1 to 11 PIX

RID


RID Format:

N1 | N2 | N3 | N4 | N5 | N6 | N8 | N9 | NA

For N1 (the first nibble):
0 .. 9 = Defined in ISO-7812
A = This ID is internationally registered
D = This ID is nationally registered
F = Not registered to any valid organization (fictious RID)

For N2 N3 N4:
These nibbles represent the country ID.


For N5 .. NA:
These nibbles are the ID of the company that holds this AID.

PIX


PIX is the Proprietary ID assigned by the company. This can be assigned without any restriction but the size.


Now, how about that?

Of course, you could just use any proprietary implementation of smartcard such as MULTOS. But, as far as I can see, the Sun's Java implementation of the smartcard have moved the card into different perspective. It has its own Security Channels and even beyond, objects not just flat files. Moreover, it is easily programmable (this is arguable because I haven't see another implementation of smartcard).

The questions addressed to Bank Indonesia as a part of their concern and to any company that would be a player in Indonesian smartcard: Are we ready for the thing? Are we already internationally accepted as one of the county that legitimately issued a card? Who would issue the AID?

Now, those are politics I dare not to touch. Not today. I suppose.

PS:

To any officials and any Indonesian player, if you would like to register Indonesia, I would like to propose UI as the first one. Please reserved these RID:
  • A0620001
  • D0620001
  • F0620001
If these still available. Btw, what is the country ID for indonesia? I just make up with the 062, that number is in use in telephony.

PS2: (Just a note of note, after I bumped in the CIA official site to find our legitimate country ID)
I honour and thankful for America for their agreement on our National Independence Day. Fyi, many countries agree that we have our Independence Day given by the Dutch after the last Agreement in Netherland in 1949 thanks to the stubborness mistake of Soekarno. Well, a good friend of mine could explain why...

EDIT:
Indonesia uses 360 as code number.

STAN vs. UI

Ugh, kasihan banget adek gue. Saking kepinteran dia jadi dapet Akuntansi UI dan STAN. Jadi bingung mau masuk yang mana. Beberapa orang (termasuk orang tua gue), menyarankan masuk STAN. Gue malah memperburuk suasana dengan membela memasuki Akuntansi UI, maklum bela almamater. Duh, gue jadi merasa bersalah bikin dia ragu-ragu. Kira-kira enakan masuk mana, yah? Gue juga gak tahu keuntungan masing-masing. Hasil debat sementara: ~ Untuk jangka panjang masuk UI, untuk jangka pendek STAN. ~~Tapi, dia itu kan cewek, ntar pas menikah kemungkinan besar karir terhambat. Eits, ntar, dulu, sekarang kan jamannya emansipasi, bisa aja cowoknya yang jadi BRT. ~ STAN sarang korupsi, kalo masuk STAN jadi pegawai negeri. Kalo mau kaya harus korupsi. Tapi kalo masuk UI, lulus masuk jadi akuntan publik. Sekarang ini, orang membayar akuntan publik untuk memanipulasi nilai pajak dan aset. *SIGH*. Jadi gak ada yang beres ~ dll. Yah, udah gue jadi bingung, apa lagi dia nanya saran gue. Buah, gue gak pengalaman ...

Installing Goodix Fingerprint Reader Driver on Fedora

I currently have a Lenovo Thinkpad L14 laptop equipped with fingerprint. I was `belok` from KDE Neon to use Fedora 40 because of someone. Now I am tempted to enable my fingerprint: lsusb | grep -i fingerprint Bus 001 Device 004: ID 27c6:55b4 Shenzhen Goodix Technology Co.,Ltd. Fingerprint Reader Dump the firmware Assuming this is a fresh install, lets do some magic by getting some dependencies: sudo dnf install gcc git python-pip python-devel openssl Let's get the source code: git clone --recurse-submodules https://github.com/goodix-fp-linux-dev/goodix-fp-dump.git cd goodix-fp-dump Create an isolated Python environment: python -m venv .v source .v/bin/activate Do the magic: sudo su pip install -r requirements.txt python run_55b4.py exit There are some python scripts available. I run run_55b4.py because my device ID is 27c6: 55b4 . It will spell some nonsense, which is a good thing. That nonsense actually the firmware captured by our device. Also, I typed exit becaus...

Vibe Coding Workflow

I am currently working for having A.I. workflow for generating projects. There are two things that need to be tackled for that: 1) hallucinations; and 2) old codes. I have met several patterns to tackle those two and just need to formulate the patterns into a general flow. Thankfully, a video of building fullstack app using A.I. from Raf Dev channel inspired me to make the formulation. He used multiple A.I. engines to his need: He used Google Gemini to onboard his ideas and summarized it. He forked a boilerplate of NextJS project into a new project. Then, he added the summary from Google Gemini into a file for context. He used QWEN Code, a QWEN3 code engine that is a fork from Gemini CLI, to build the project. When working with an existing project, A.I. will take the whole project as a context. It also means that it will stick with the version used by the libraries. It also will try to update its knowledge based on the common pattern in the project. Most of the time, it will use the c...
