CRCsjekk
CRCsjekk, often written as CRC-sjekk, refers to the process of using a cyclic redundancy check (CRC) to verify the integrity of data in digital systems. A CRC is a short, fixed-size value derived from the data through polynomial division. The resulting checksum is stored or transmitted with the data, and the receiver recomputes the CRC to see if the data have been altered in transit or storage.
The strength of a CRC depends on the chosen polynomial and the size of the CRC (for
Implementation typically involves choosing an initial value, applying bitwise or table-driven calculations as data is processed,
Limitations include that CRCs are designed for error detection rather than data authentication; they do not
