描述
Thank you for great tool!
It will be nice to see algorithms from ISO14443 and ISO13239 contactless smartcards standards.
- CRC16_A Initial register
0x6363or0xC6C6in reversed bit order. Polynomial is0x1021and no final XOR. - CRC16_B
- BCC (Bit Count Check) — simple successively XOR-ing all bytes
I've made my own calculator for example https://hub.zhovner.com/tools/nfc/
