During the authentication process, the entered information is converted into a hash value, which is then compared with the original information. Examples include and operating systems. Account login passwords are only stored as hashed values. Information search acceleration When filling rows in the information base, hash codes can be created from stored names, so new data can be placed in various sections based on hash codes. Then, to find the information you need, you just need to convert it to a hash value, after which it will be clear which part it is in.
Thus, the search time is reduced: the Whatsapp Number List search is no longer performed in all sections, but only in the section corresponding to the hash code of the information being searched for. Hash Application Hash Application Example. You have a catalog on your computer that contains various products. It is sorted alphabetically. The first letter of each item will be its hash code. In order to quickly find the desired product, you do not need to search for it throughout the catalog just enter the first letter of the name. Properties and Requirements of Cryptographic Hash Features of cryptographic hash functions: Irrevocability.
All attempts to extract the input data after hashing are doomed to failure, as most information is lost during conversion to code (as opposed to traditional encryption). fate. When you input the same information to perform a hash function, the resulting value will always be the same. This makes it possible to use hashes to verify the authenticity of existing data. unique. A hash function may always return a unique code. But so far, this has not been implemented in practice, and occasionally there will be doubles of the same value for different data. However, the quality of the hash minimizes the risk of duplication. various kinds.
