what is secure hash algorithm?-Definition of all finance terms

Definition of SHA (Secure Hash Algorithm)

SHA stands for the secure hash algorithm. It is one hash function of the cryptographic world that 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 that consists of a number of different bits.

Brief Explanation of SHA 

It compares two computed values from which one is known and another is an expected value. With the help of this function results, a person can find integrity in a given data. SHA also performs 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.
