![]() ![]() ![]() Some of the most used hash functions are: I want to make clear that hash functions are not a cryptographic protocol, they do not encrypt or decrypt information, but they are a fundamental part of many cryptographic protocols and tools. As a Python programmer you may need these functions to check for duplicate data or files, to check data integrity when you transmit information over a network, to securely store passwords in databases, or maybe some work related to cryptography. #String split universal database passwordHash functions are used inside some cryptographic algorithms, in digital signatures, message authentication codes, manipulation detection, fingerprints, checksums (message integrity check), hash tables, password storage and much more. Now suppose you want to hash the string "Hello Word" with the SHA1 Function, the result is 0a4d55a8d778e5022fab701977c5d840bbc486d0. However depending on the algorithm, there is a possibility to find a collision due to the mathematical theory behind these functions. The value returned by a hash function is often called a hash, message digest, hash value, or checksum. Most of the time a hash function will produce unique output for a given input. This means if f is the hashing function, calculating f(x) is pretty fast and simple, but trying to obtain x again will take years. Last Updated: Wednesday 29 th December 2021Ī hash function is a function that takes input of a variable length sequence of bytes and converts it to a fixed length sequence. ![]()
