Secure Hash Algorithm is a group of cryptographic hashing algorithm which was extra like by the National Institute of Standards and Technology (NIST) with the main aim of securing data. SHA-1 is one of the very common types and employed cryptographic hash algorithm. It was one of the most backdated (far back as 1995) hash algorithms chosen by the United States federal government. It collects data and gives out about 160-bit hash worth popularly referred to as a message digest.

The SHA-1 is fashioned in such a manner that it is able to computationally find data that is similar to a given message digest. It is a hash function generally used in Blockchain. SHA-256 is a modern and safer cryptographic hash function which came into being in 2002. The SHA-256 algorithm gives out a 256-bit hash value from padded 512-bit message blocks, and the original message size is up to 264-1 bits. SHA-256 is of the same family with SHA-384 and SHA-512, all of which are of the SHA-2 family of cryptographic hashing algorithms with the same hash functions but different block sizes.SHA-256, so far, has not been known to be susceptible to any form of attack.

SHA stands for Secure Hash Algorithm. It is a grouping of cryptographic hashing algorithms circulated in the National Institute of Standards and Technology. It aims to store and preserve your data. In the mid-’90s, the NIST accepted the Secure Hash Standard, which included one secure hash algorithm called the SHA-1. In 2003, a modern Secure Hash Signature Standard was approved, which added three hash algorithms with the ability to generate larger message digests.

SHA-1 SHA-1 is one of the most extensively utilized and deployed cryptographic. It was one of the oldest has a has algorithms specified for use by the United States federal government. NIST and the NSA developed it. SHA-256 is a newer, more secure hash function which was projected in 2000 as a new generation of SHA functions and was created as FIPS standard in 2002.
