A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with fixed size of $${\displaystyle n}$$ bits) that has special properties desirable for a cryptographic application: the probability of a particular $${\displaystyle n}$$-bit output result (hash … See more Most cryptographic hash functions are designed to take a string of any length as input and produce a fixed-length hash value. A cryptographic hash function must be able to withstand all … See more Verifying the integrity of messages and files An important application of secure hashes is the verification of message integrity. Comparing message digests (hash digests over the message) calculated before, and after, transmission … See more Merkle–Damgård construction A hash function must be able to process an arbitrary-length message into a fixed-length output. This … See more Concatenating outputs from multiple hash functions provide collision resistance as good as the strongest of the algorithms included in the concatenated result. For example, older versions of Transport Layer Security (TLS) and Secure Sockets Layer (SSL) used … See more When a user creates an account on a website, they are typically asked to create a password. Rather than storing the password in plain … See more There are several methods to use a block cipher to build a cryptographic hash function, specifically a one-way compression function. The methods resemble the block cipher modes of operation usually used for encryption. Many … See more Hash functions can be used to build other cryptographic primitives. For these other primitives to be cryptographically secure, care must be taken to build them correctly. Message authentication codes (MACs) (also called keyed hash functions) are often built from … See more WebThe hashcode () Method works in java by returning some hashcode value just as an Integer. This hashcode integer value is vastly used in some hashing based collections, which are like HashMap, HashTable, HashSet, etc. The hashcode () method of Java is needed to be overridden in every class, which helps to override the methods like equal ().
