A Secure Hash Algorithm (SHA) checksum is a digital fingerprint of a file that ensures its integrity by verifying it has not been tampered with or corrupted. A hash is created by passing the file content through a one-way mathematical function, resulting in a fixed-size string of characters (e.g., 256-bit SHA-256). When a file is downloaded or transferred, the receiver can compute the SHA checksum and compare it to the original value, ensuring authenticity.
