Cryptographic_Hash_Functions.docx (1) Cryptographic Hash Function DAT/305 Definition A cryptographic hash function is a mathematical function used in cryptography and is an essential part of cyb ... ersecurity. Typical hash functions take inputs of variable lengths to return outputs of a fixed length. Cryptographic hash functions add security features to typical hash functions, making it more difficult to detect the contents of a message or information about recipients and senders.Â Hash functions are commonly used data structures in computing systems for tasks, such as checking the integrity of messages and authenticating information. While they are considered cryptographically "weak" because they can be solved in polynomial time, they are not easily decipherable. FrankenfieldÂ (2020). Cryptographic Hash Function Properties According toÂ BlockgeeksÂ (nd), cryptographic hash function is a special class of hash functions which has various properties making it ideal for cryptography. There are certain properties that a cryptographic hash function needs to have in order to be considered secure. Let™s run through them one by one. Property 1: Deterministic This means that no matter how many times you parse a particular input through a hash function you will always get the same result. This is critical because if you get different hashes every single time it will be impossible to keep track of the input. Property 2: Quick Computation The hash function should be capable of returning the hash of an input quickly.
