CRC Detective
Identify unknown CRC algorithms from data and expected output
Input
Data
Hex bytes
ASCII
Space or comma-separated hex bytes — e.g.
DE AD BE EF
Repeat (×)
Concatenate data X times
Expected CRC Output (hex)
The known CRC value to match against
CRC Width:
Auto
8-bit
16-bit
24-bit
32-bit
Auto detects width from the expected CRC value; or select a fixed width
