Frequently Asked Questions
What is CRC32?
Cyclic Redundancy Check 32-bit is a checksum algorithm used to detect accidental changes to raw data.
Is CRC32 secure?
No, it is designed for error detection (e.g., in network packets), not for security hashing.
When to use CRC32?
For checking file integrity during transfer or storage where intentional tampering is not a concern.
