How to use the CRC32() function in MySQL and MariaDB databases
The CRC32() function in MySQL and MariaDB is commonly used to generate a checksum value to verify data integrity or to identify duplicate records based on their CRC-32 checksums to identify. This can be useful in scenarios such as data synchronization, error detection or data deduplication. The CRC-32 algorithm is a hash function that produces a relatively short checksum, making it susceptible to collisions. Therefore, it is not suitable for cryptographic purposes where collision resistance is critical.
