    In computer science, a hash list is typically a list of hashes of the data blocks in a file or set of files. Lists of hashes are used for many different purposes, such as fast table lookup (hash tables) and distributed databases (distributed hash tables). A hash list with a top hash. A hash list is an extension of the concept of hashing an item ...

    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 ...

    Although the RDS hashset contains some malicious software (such as steganography and hacking tools) it does not contain illicit material (e.g. indecent images). The collection of original software media is maintained in order to provide repeatability of the calculated hash values, ensuring admissibility of this data in court.

    The hash function creates a message digest, a relatively short code calculated from each bit in the file using an algorithm that creates large changes in the message digest with even smaller changes to the original file. By recalculating and comparing the message digest of the installed files at regular intervals against a trusted list of ...
