SHA-1 was created later in 1995 to address perceived flaws in SHA-0. SHA-1 is the most widely used of the existing SHA hash functions. It is used in most of the applications and protocols including Secure Socket Layer (SSL) security. In 2005, a technique was discovered for SHA-1 ...

Good Hash Functions A good hash function may not prevent the collisions completely however it can reduce the number of collisions. Here, we will look into different methods to find a good hash function 1. Division Method If k is a key and m is the size of the hash table, the hash func...

What is MAC-based on Hash Function (HMAC) in Cryptography?This Hashed or Hash-based Message Authentication Code in cryptography. Thus, developing a MAC derived from cryptographic hash functions in this. Mainly, HMAC is a great resistance towards cryptanalysis attacks as it uses the hashing concept...
