Вы сможете снимать отпечатки с ваших важных файлов и потом проверять их целостность после передачи их по сети или после записи на диски, просто снова снимая отпечатки с переданных данных и сравнивая их со сделанным заранее отпечатками.
Таким же способом, вы сможете найти, какие файлы были повреждены вирусами, повреждены из-за проблем с сетью или из-за ошибок при записи. Для экономии вашего времени, FastSum основан на очень хорошо известном и проверенном времени криптографическом алгоритме MD5 checksum, который производит все вычисления очень быстро и надежно. Вы сможете обработать тысячи файлов за раз и посмотреть как работает данная программа. Данная утилита специально разработана для таких случаев и совершенно не требует больших компьютерных мощностей.
FastSum is build upon the well proven MD5 checksum algorithm which is used worldwide for checking integrity of the files, and been used for this purpose for at least the last 10 years. FastSum provides you with three interfaces from the console application for technician professionals to modern graphical application for any-level users.
What's inside?
When you select files FastSum computes their checksums according to the MD5 checksum algorithm, which can be easily compared with previously computed checksums or stored for future integrity checking. There are two most important MD5 checksum properties for the end-user: the fixed size and the non-discoverability. The first property means that it does not matter how big the source file is, it always has a short 128bit MD5 checksum value that can be compactly stored and easily shared. While the second property implies that a pair of nonidentical files will have different MD5 checksum value i.e. even a short fixed size value is enough for detecting changes within the file.

Checksum Verification Wizard
No computer on earth is equipped with 100% reliable storage device and no network delivers the content absolutely faultlessly. Thanks to the MD5 checksum that detects errors an octillion times better than the regular 32bit error detection algorithms (which are used in storage devices and network protocols), FastSum provides more than sufficient accuracy. You can create MD5 checksums for important files and store them for future integrity checking. For example, a checksum list burned on a CD will allow you to detect problems early: if FastSum finds any between-checksums differences, then it is time to transfer your data onto another storage device while it’s not yet completely lost! You can also detect changed, deleted and newly created files in your everyday life, as well as check the integrity of the data downloaded from the Internet [when its checksums are also provided *]
Several ways to do the same
FastSum comes with three interfaces, from the console application to modern graphical application. So, you can choose the way that fits the situation best. The Standard Edition allows FastSum to be integrated into Windows® Explorer, which makes the access to the MD5 checksum creation and verification procedures much easier. You also are enabled to calculate the MD5 checksums for several selected files as well as for multiple folders and even entire drives. The built-in Wizards give the best fit for processing a great number of files. At that the Verification Wizard is able to find new files and calculate their MD5 checksums.
