Checksums are an important part of all functions of computing they offer methods of providing data a string or otherwise know as a set length impression to the data so it can be verified that it is functionally and completely the same. Checksums are part of cryptology that offer finite measurement of data and ensure that there is a lot of functionality in the methods of data verification. Checksums are also referred to as hashes.

The nice feature of the QCP64 is the lack of repetitive numbering, many checksums/hashes are defined by long occurrences of numerical expression (it was time to change, this).

QCP64 has 3 many items 2 of which have defaults, there is a seed between 1 - 255 where it will seed the based and produce the hash/checksum for you in various different bases, it also has a variable length, default 27 characters. You can alter these which will change the checksum as well. You can see your text.

A hash function is any well-defined procedure or mathematical function for turning some kind of data into a relatively small integer, that may serve as an index into an array. The values returned by a hash function are called hash values, hash codes, hash sums, or simply hashes. Hash/checksum functions are mostly used to speed up table lookup or data comparison tasks ? such as finding items in a database, detecting duplicated or similar records in a large file, finding similar stretches in DNA sequences, and so on.

Hash functions are related to (and often confused with) checksums, check digits, fingerprints, randomizing functions, error correcting codes, and cryptographic hash functions. Although these concepts overlap to some extent, each has its own uses and requirements. The HashKeeper database maintained by the National Drug Intelligence Center, for instance, is more aptly described as a catalog of file fingerprints than of hash values.

Testimonies

A Queen Council Stated : "It is one of the finest checksums I have seen and spoken of"

A Quantum Computing Programmer : "I can't believe how the performance of my systems and the ability of this checksum to remain unchanged and none reversible with functional differences."
