Hashish (/ h ə ˈ ʃ iː ʃ / ⓘ; from Arabic ḥašiš 'hay'), usually abbreviated as hash, is a compressed form of resin (trichomes) derived from the marijuana flowers. [ 3 ] [ 4 ] As a psychoactive substance , it is consumed plain or mixed with tobacco .
HAVAL is a cryptographic hash function. Unlike MD5, but like most modern cryptographic hash functions, HAVAL can produce hashes of different lengths – 128 bits, 160 bits, 192 bits, 224 bits, and 256 bits. HAVAL also allows users to specify the number of rounds (3, 4, or 5) to be used to generate the hash. HAVAL was broken in 2004. [1]
Hash oil or cannabis oil is an oleoresin obtained by the extraction of cannabis or hashish. [1] It is a cannabis concentrate containing many of its resins and terpenes – in particular, tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids .
A spirit duplicator (also Rexograph and Ditto machine in North America, Banda machine and Fordigraph machine in the U.K. and Australia) is a printing method invented in 1923 by Wilhelm Ritzerfeld, which was used for most of the 20th century. The term "spirit duplicator" refers to the alcohols that were the principal solvents used in generating ...
The high-level structure of the new hash function resembles the one from GOST R 34.11-94, however, the compression function was changed significantly. [5] The compression function operates in Miyaguchi–Preneel mode and employs a 12-round AES-like cipher with a 512-bit block and 512-bit key. (It uses an 8×8 matrix of bytes rather than AES's 4 ...
Hopscotch hashing is a scheme in computer programming for resolving hash collisions of values of hash functions in a table using open addressing. It is also well suited for implementing a concurrent hash table. Hopscotch hashing was introduced by Maurice Herlihy, Nir Shavit and Moran Tzafrir in 2008. [1]
Here is the formal technical definition of the puzzle friendliness property. [2] [1]A hash function H is said to be puzzle friendly if for every possible n-bit output value y, if k is chosen with a distribution with high min-entropy, then it is infeasible to find x such that H( k || x) = y (where the symbol "||" denotes concatenation) in time significantly less than 2 n.
Panama is a cryptographic primitive which can be used both as a hash function and a stream cipher, but its hash function mode of operation has been broken and is not suitable for cryptographic use. Based on StepRightUp , it was designed by Joan Daemen and Craig Clapp and presented in the paper Fast Hashing and Stream Encryption with PANAMA on ...
