WebCRC (Cyclic Redundancy Check) is a checksum algorithm to detect inconsistency of data, e.g. bit errors during data transmission. A checksum, calculated by CRC, is attached to the data to help the receiver to detect such errors. ...

A CRC is not processor-intensive. All it adds to your exclusive-or is a table lookup. The operation on each byte is simply: crc = crc8_table [crc ^ *data++]. See below. The downside of doing just an exclusive-or is that there are many simple errors that cancel each other, resulting in a false-positive check. A CRC is much better. black iron oxide orgonite
