Generating checksums—cryptographic hashes such as MD5 or SHA-256 functions for files is hardly anything new and one of the most efficient means to ascertain the integrity of a file, or to check if two ...

Often, files that are distributed over the Internet are provided with a checksum number for security and file validity. While they are not needed, some people may wish to verify their downloads with ...

Back in June I reported on how Google's Checksum algorithm was backwards engineered. Since then, dozens of PageRank tools became available. There has been a few backlink updates at Google since the ...

Checksum algorithms are used in biological databases for integrity check and identification purposes. CRC64 is the only checksum algorithm already included in Biopython. This work proposes two new ...

We are often struck by how often we spend time trying to optimize something when we would be better off just picking a better algorithm. There is the old story about the mathematician Gauss who, when ...

A checksum is a string of characters which uniquely identifies afile, a digital fingerprint. Change even a few bytes of a file–forexample, by infecting it with a virus or replacing an old versionwith ...

My question is, what part of the file is being checksummed? It could be a chunk in the middle, it could be everything after the first 180 bytes (or 200, or 431, etc), it could be every 4th byte in the ...
