The MD5 hash functions as a compact digital fingerprint of a file. As with all such hashing algorithms, there is theoretically an unlimited number of files that will have any given MD5 hash. However, it is very unlikely that any two non-identical files in the real world will have the same MD5 hash, unless they have been specifically created to ...
md5deep is a software package used in the computer security, system administration and computer forensics communities to run large numbers of files through any of several different cryptographic digests. It was originally authored by Jesse Kornblum, at the time a special agent of the Air Force Office of Special Investigations.
A file can become corrupted by a variety of ways: faulty storage media, errors in transmission, write errors during copying or moving, software bugs, and so on. Hash-based verification ensures that a file has not been corrupted by comparing the file's hash value to a previously calculated value. If these values match, the file is presumed to be ...
Metalink is an extensible metadata file format that describes one or more computer files available for download.It specifies files appropriate for a user's language and operating system; facilitates file verification and recovery from data corruption; and lists alternate download sources (mirror URIs).
Linux kernel, version 5.17 replaced SHA-1 with BLAKE2s for hashing the entropy pool in the random number generator. [21] Open Network for Digital Commerce, a Government of India initiative, uses BLAKE-512 to sign API requests. [22] checksum, a Windows file hashing program has Blake2s as one of its algorithms [23]
The lookup3 function consumes input in 12 byte (96 bit) chunks. [9] It may be appropriate when speed is more important than simplicity. Note, though, that any speed improvement from the use of this hash is only likely to be useful for large keys, and that the increased complexity may also have speed consequences such as preventing an optimizing compiler from inlining the hash function.
The MD6 Message-Digest Algorithm is a cryptographic hash function. It uses a Merkle tree -like structure to allow for immense parallel computation of hashes for very long inputs. Authors claim a performance of 28 cycles per byte for MD6-256 on an Intel Core 2 Duo and provable resistance against differential cryptanalysis . [ 3 ]
The Toeplitz Hash Algorithm is used in many network interface controllers for receive side scaling. [ 2 ] [ 3 ] As an example, with the Toeplitz matrix T {\displaystyle T} the key k {\displaystyle k} results in a hash h {\displaystyle h} as follows:
