Understanding Checksum Calculation
Checksum is like a special code that you can calculate from data to check for errors. It’s similar to a digital fingerprint, which helps you make sure the data is correct. It helps you catch errors or differences and make sure the data is reliable.
There are several checksum algorithms commonly used to calculate checksums, such as CRC, MD5, and SHA-1. CRC (Cyclic Redundancy Check) is for error detection, while MD5 (Message Digest 5) and SHA-1 (Secure Hash Algorithm 1) provide unique checksums for data integrity and protection.
