Hash vs checksum

WebNov 11, 2024 · To calculate a checksum, we run a program that puts that file through a hash function. The frequently used algorithms are MD5, SHA-1, SHA-256, and SHA-512. The hash function takes the input and produces a string of a fixed length. For the same input, the hash function always returns the same checksum value.

If you pass it a block with the checksum on the end, it will give you zero for a good checksum, or non-zero if the checksum is bad. This is the simplest approach and will detect most random errors. spooks fanfiction https://envisage1.com
