<prompt> Hlalosa hore na mosebetsi oa hash ke eng.nan  <response>: Instruction in English: Describe what is a hash function. . Response in English: A hash function is a mathematical algorithm that takes an input, or key, and returns a fixed-size string of bytes, typically used to index data in hash tables. The result, or hash value, is a seemingly random, but determinable, value that represents the original data. A good hash function should have the property that different keys should have a very low probability of producing the same hash value, which is called a collision. Hashing is commonly used to verify the integrity of data, index data in hash tables, find duplicated records, and facilitate data retrieval. Some common hash functions include SHA Secure Hash Algorithm, MD5 Message-Digest algorithm 5, and CRC Cyclic Redundancy Check. . Response in Sesotho: Hash function ke algorithm ea lipalo e nkang tlhahiso, kapa key, me e khutlisa khoele ea boholo bo sa fetoheng ea li-byte, eo hangata e sebelisetsoang ho supa data ho litafole tsa hash. Sephetho, kapa hash value, ke boleng bo bonahalang bo sa iketsahalle, empa bo ka lekanyetsoa bo emelang data ea mantlha. Mosebetsi o motle oa hash o lokela ho ba le thepa eo linotlolo tse fapaneng li lokelang ho ba le monyetla o tlaase haholo oa ho hlahisa boleng bo tšoanang ba hash, bo bitsoang ho thulana. Hashing e atisa ho sebelisoa ho netefatsa botšepehi ba data, lintlha tsa index litafoleng tsa hash, ho fumana litlaleho tse kopitsoang, le ho thusa ho khutlisa data. Mesebetsi e meng e tloaelehileng ea hash e kenyelletsa SHA Secure Hash Algorithm, MD5 Message-Digest algorithm 5, le CRC Cyclic Redundancy Check.
