CRC8 Checksum

Description

This operation calculates an 8-bit Cyclic Redundancy Check (CRC) value for a given input. A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data.

The algorithm uses a fixed 8-bit polynomial to calculate a short "fingerprint" of the input data, resulting in an 8-bit (one-byte) checksum. This checksum can detect certain types of errors, like single-bit errors or burst errors up to 8 bits, by recalculating the checksum and comparing it with the original.

Data types

These are the input/output expected data types for this operation:

Input data

- Data you want to compute the CRC-8 checksum for.

Output data

- CRC-8 values of your input data.

Example

Suppose you want to calculate the CRC-8 of a specific set of data:

1. In your Pipeline, open the required Action configuration and select the input Field.

2. In the Operation field, choose CRC8 Checksum.

3. Give your Output field a name and click Save. The operation will calculate the CRC8 codes for the strings in your input field. For example:

hello 1234 -> C7

You can try out operations with specific values using the Input field above the operation. You can enter the value in the example above and check the result in the Output field.
