Hello everyone,
I have implemented Ascon-128 AEAD in Javascript, and made a simple webpage to make it easy to test and play with online from browser. Hence, I called it "playascon". Hope you'll enjoy it.

Hi lwc forum,

I have updated many things in playascon, which is basically a Javascript implementation of Ascon made as online tool.

(playascon: https://motarekk.github.io/):

- Supported variants: Ascon-128, Ascon-128a, Ascon-XOF, Ascon-XOFa

- Input can be raw text (English or non-English) or hexadecimal value

- Added a KATs page to run Known Answer Tests that was generated from genkat.py file in pyascon

- An easy Capture The Flag (CTF) challenge, and will add more to make it more fun for students and help them get hands on how attacks like nonce misuse could take place

- I have explained more details in this blogpost:

I hope this tool will be helpful for students to test Ascon and play out with it.
