File Hash Checker - простой инструмент для вычисления MD5 и SHA1 хэша и контрольных сумм любого файла. Может быть полезен для пользователей, которые сохраняют данные на жестком диске в формате ISO, для обеспечения целостности образа. Также выступает в роли обычного генератора хэшей. Встраивается в меню правой кнопки мыши.

A checksum is a digit which serves as a sum of correct digits in data, which can be used later to detect errors in the data during storage or transmission. MD5 Message Digest 5 sums can be used as a checksum to verify files or strings in a Linux file system. MD5 Sums are bit character strings numerals and letters resulting from running the MD5 algorithm against a specific file. The MD5 algorithm is a popular hash function that generates bit message digest referred to as a hash value, and when you generate one for a particular file, it is precisely unchanged on any machine no matter the number of times it is generated. It is normally very difficult to find two distinct files that results in same strings. Therefore, you can use md5sum to check digital data integrity by determining that a file or ISO you downloaded is a bit-for-bit copy of the remote file or ISO.

The MD5 sum is a kind of digital signature for files and zip packages to check the intactness of files. Most official and custom ROMs, mods and recovery flashable ZIPs come pre-encrypted with a unique code for security reasons. You can assign an MD5 sum even to a text or document file. The perfect match of MD5 checksum value ensures that the digital integrity and security of a file has not been broken by someone else and also that it is the accurate copy of the original file. Thus, there are the two main reasons if the MD5 hash value of a file you downloaded does not match against the original sum:. Installing an official firmware, a custom ROM or even a Kernel file with corrupt MD5 value can lead to a bricked phone or tablet. I have seen various cases where people report that their device went to bricked state after installing a certain file. In many cases, you might get an installation failed error if the MD5 hash value is not correct.

What is MD5 Checksum and How to Use it:

Duplicate Article This article covers the same material as another article. More info The program md5sum is designed to verify data integrity using the MD5 Message-Digest algorithm 5 bit cryptographic hash. MD5 hashes used properly can confirm both file integrity and authenticity. In terms of integrity, an MD5 hash comparison detects changes in files that would cause errors.
