Definition of SHA (Secure Hash Algorithm)
SHA stands for the secure hash algorithm. It is one a hash function of the cryptographic world. Which is working on all digitized data by algorithm operations, it was introduced by NSA (national security agency) in the USA. SHA is a novel hash function which consists of a number of different bits.
Breif Explanation of SHA (Secure Hash Algorithm)
This secure hash algorithm compares two computed values from which one is known and another is expected value. With the help of this function results, a person can find integrity in a given data. SHA also perform one key function of cryptography. It can able to determine two different input values that occurred in the same hash output. This function is known as collision resistance. The family of this secure algorithm function consists of six hash functions with different bits. SHA common functions include SHA-1, SHA-2, and SHA-3.
