To maintain data integrity in cryptography,hash functions,which return a deterministic output from an input value, are used to map data to a fixed data size. Types of cryptographic hash functions include SHA-1 (Secure Hash Algorithm 1), SHA-2 and SHA-3. Cryptography concerns Attackers can byp...
Hash Function Hash functions ensure that data integrity is maintained in the encryption and decryption phases of cryptography. It is also used in databases so that items can be retrieved more quickly. Hashing is the process of taking a key and mapping it to a specific value, which is the ha...
this type of cryptography does not use a cryptographic key. Hash functions help ensure data integrity between communicating parties. If the hash produces the same output, it indicates that the information has not been altered, compromised

Hash Functions Cryptographic hash functions are formulas that process input data, like documents or messages, of any size. It generates a unique fixed-length string known as a hash value. These one-way encryption functions aim to prevent collisions (collision of twohash values), making it challen...
Elliptic curve cryptography (ECC)− It is a modern type of asymmetric encryption that generates very strong cryptographic keys using the algebraic structures of elliptic curves. Hash Functions A hash function is like a special mathematical function which takes an input of arbitrary data like text,...
This is a type of cryptographic brute-force attack for obtaining digital signatures, passwords and encryption keys by targeting the hash values used to represent them. It's based on the "birthday paradox," which states that, in a random group of 23 people, the chance that two of them have...
Hashing functions are an essential part of cybersecurity and some cryptocurrency protocols such as Bitcoin. Hashing converts any form of data into a unique string of text. It is a mathematical operation that is easy to perform, but difficult to reverse. The average user encounters hashing daily...

SHA-2– SHA-2, developed by the National Security Agency (NSA), is a cryptographic hash function. SHA-2 includes significant changes from its predecessor, SHA-1. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: SHA-224, ...
