Checksum — A checksum is a calculated value that helps detect changes in data. Systems commonly use checksums to identify transmission errors or accidental corruption. Ordinary checksums do not provide the same protection against deliberate manipulation as appropriately designed cryptographic integrity controls. – Data Integrity

Checksum — A checksum is a calculated value used to help detect changes or errors in data. A system recalculates the value and compares it with an expected value to identify a mismatch. Ordinary checksums do not provide reliable protection against deliberate tampering because an attacker can sometimes alter both the data and its checksum.
