Hi there,
I developed a simple tool to modify Mifare Classic dump on the web browser.
It can:
- Edit dump file from Flipper Zero NFC and MCT.
- Convert dump file.
- Check access bits of each blocks.
- Warn if access bits will block your card.
- Open Source.
- Pure JavaScript, Server-less.
Here is link to it, https://pccr10001.github.io/mifare.html
Suggestions are welcome.
