Hashtab wikipedia5/15/2023 ![]() Such a pair is called a cryptographic hash collision. Collision resistance It should be difficult to find two different messages m 1 and m 2 such that hash( m 1) = hash( m 2). Functions that lack this property are vulnerable to second-preimage attacks. This property is sometimes referred to as weak collision resistance. Second pre-image resistance Given an input m 1, it should be difficult to find a different input m 2 such that hash( m 1) = hash( m 2). Functions that lack this property are vulnerable to preimage attacks. This concept is related to that of a one-way function. Pre-image resistance Given a hash value h, it should be difficult to find any message m such that h = hash( m). In theoretical cryptography, the security level of a cryptographic hash function has been defined using the following properties: Most cryptographic hash functions are designed to take a string of any length as input and produce a fixed-length hash value.Ī cryptographic hash function must be able to withstand all known types of cryptanalytic attack. Indeed, in information-security contexts, cryptographic hash values are sometimes called ( digital) fingerprints, checksums, or just hash values, even though all these terms stand for more general functions with rather different properties and purposes. They can also be used as ordinary hash functions, to index data in hash tables, for fingerprinting, to detect duplicate data or uniquely identify files, and as checksums to detect accidental data corruption. Retrieved January 5, 2017.A cryptographic hash function ( CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with fixed size of n bits (lower due to the birthday paradox).Ĭryptographic hash functions have many information-security applications, notably in digital signatures, message authentication codes (MACs), and other forms of authentication. Yummy Potatoes: 65 Downright Delicious Recipes. Backcountry Cooking: From Pack to Plate in 10 Minutes. Miss Parloa's kitchen companion : a guide for all who would be good housekeepers. Frozen hash browns are scored on color, defects, texture grading also is based on flavor and odor. Frozen Food Encyclopedia for Foodservice: Formerly Frozen Food Institutional Encyclopedia. Okay, So Now You're a Vegetarian: Advice and 100 Recipes from One Vegetarian to Another. ^ a b c Slater, Nigel (November 4, 2006).Some recipes add diced or chopped onions. In some parts of the United States, hash browns strictly refer to shredded or riced pan-fried potatoes, while diced and pan-fried potatoes are called country fried potatoes or home fries and are served as a side dish at other meals. Hash browns are also manufactured as a dehydrated food, which is sometimes used by backpackers. If a dish of hash browned potatoes incorporates chopped meat, leftovers, or other vegetables, it is more commonly referred to as hash. ![]() For best results, in both cooking and flavor, it is recommended that hash browns be made using starchy potatoes such as russet potatoes. Hash browns are sometimes made into patty form and frozen for ease of handling, and the compact, flat shape can also be cooked in a toaster oven or toaster. Triangular hash brown patties served with egg, bacon and sausage in a British cafeĪ chef may prepare hash browns by either grating potato or forming riced potatoes into patties before frying with onions (moisture and potato starch can hold them together) however, if a binding agent is added (egg or flour for example), such a preparation constitutes a potato pancake. This means hashed browned potatoes literally translates to "chopped and fried potatoes". The word hash is derived from the French word " hacher", which means to hack or chop. The name was gradually shortened to "hash brown potatoes". ![]() Originally, the full name of the dish was "hashed brown potatoes" (or "hashed browned potatoes"), of which the first known mention is by American food author Maria Parloa (1843–1909) in her 1887 Kitchen Companion, where she describes the dish of "hashed and browned potatoes" as a fried mixture of cold boiled potatoes which is folded "like an omelet" before serving. Hash browns first started appearing on breakfast menus in New York City in the 1890s. Hash browns are a popular mass-produced product sold in refrigerated, frozen and dehydrated forms. Hash browns are a staple breakfast food at diners in North America, where they are often fried on a large common cooktop or grill. Hash browns, also spelled hashed browns and hashbrowns, are a popular American breakfast dish consisting of finely julienned potatoes that have been fried until browned.
