    Among other features, it can calculate various checksums, compare files, or shred files. [1] HxD is distributed as freeware and is available in multiple languages of which the English version is the first in the category of coding utilities on Download.com. [2] The c't magazine has featured HxD in several issues and online-specials. [3] [4]

  3. File verification - Wikipedia

    en.wikipedia.org/wiki/File_verification

    CRC checksums cannot be used to verify the authenticity of files, as CRC32 is not a collision resistant hash function -- even if the hash sum file is not tampered with, it is computationally trivial for an attacker to replace a file with the same CRC digest as the original file, meaning that a malicious change in the file is not detected by a ...

    en.wikipedia.org/wiki/Comparison_of...

    The following tables compare general and technical information for a number of cryptographic hash functions. See the individual functions' articles for further information. This article is not all-inclusive or necessarily up-to-date. An overview of hash function security/cryptanalysis can be found at hash function security summary.

  5. Checksum - Wikipedia

    en.wikipedia.org/wiki/Checksum

    Checksums are used as cryptographic primitives in larger authentication algorithms. For cryptographic systems with these two specific design goals [ clarification needed ] , see HMAC . Check digits and parity bits are special cases of checksums, appropriate for small blocks of data (such as Social Security numbers , bank account numbers ...

    Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity).

  9. Secure Hash Algorithms - Wikipedia

    en.wikipedia.org/wiki/Secure_Hash_Algorithms

    SHA-2: A family of two similar hash functions, with different block sizes, known as SHA-256 and SHA-512. They differ in the word size; SHA-256 uses 32-bit words where SHA-512 uses 64-bit words. There are also truncated versions of each standard, known as SHA-224, SHA-384, SHA-512/224 and SHA-512/256. These were also designed by the NSA.
