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 ...

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 ...

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 ...

Google started deploying a new toolbar update with an updated PageRank checksum algorithm (see this entry), but it didn't take them long to crack the new algorithm this time around (Google hasn't even ...

[BaronVonSchnowzer] is spinning up some home automation and settled on an inexpensive ambient temperature sensor which is sold to augment the data a home weather station collects. He found that the RF ...

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 ...

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 ...
