BLAKE is a cryptographic hash function based on Daniel J. Bernstein 's ChaCha stream cipher, but a permuted copy of the input block, XORed with round constants, is added before each ChaCha round. Like SHA-2, there are two variants differing in the word size. ChaCha operates on a 4×4 array of words. BLAKE repeatedly combines an 8-word hash ...
The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA".
RIPEMD ( RIPE Message Digest) is a family of cryptographic hash functions developed in 1992 (the original RIPEMD) and 1996 (other variants). There are five functions in the family: RIPEMD, RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320, of which RIPEMD-160 is the most common. [citation needed] The original RIPEMD, as well as RIPEMD-128, is ...
Steganography tools. A steganography software tool allows a user to embed hidden data inside a carrier file, such as an image or video, and later extract that data. It is not necessary to conceal the message in the original file at all. Thus, it is not necessary to modify the original file and thus, it is difficult to detect anything.
Variable. Default, Unkeyed=40+ [d/4], Keyed=max (80,40+ (d/4)) [ 1] Best public cryptanalysis. Key-recovery attack of a 14-round MD6 function in 2 22 operations. [ 2] 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.
Nilsimsa Hash is an anti-spam focused locality-sensitive hashing algorithm. ssdeep is a fuzzy hashing tool based on context-piecewise triggered hashing to compare files. [4] sdhash is a fuzzy hashing tool based on using bloom filters to determine whether one file is contained within another or how similar two files are to each other. [11]
The Whirlpool hash function is a Merkle–Damgård construction based on an AES -like block cipher W in Miyaguchi–Preneel mode. [ 2] The block cipher W consists of an 8×8 state matrix of bytes, for a total of 512 bits. The encryption process consists of updating the state with four round functions over 10 rounds.
In cryptography, an SP-network, or substitution–permutation network ( SPN ), is a series of linked mathematical operations used in block cipher algorithms such as AES (Rijndael), 3-Way, Kalyna, Kuznyechik, PRESENT, SAFER, SHARK, and Square . Such a network takes a block of the plaintext and the key as inputs, and applies several alternating ...
