Hashing Algorithm – Network Encyclopedia

Sep 22, 2001 Hashing Algorithm: the complete guide to understand SHA-256 (“Secured Hash Algorithm 256″) is the algorithm which has been chosen by the designers of the Protocol Bitcoin. It is used during the creation of the public key from the private key, but also for the realization of the process of proof of work. How does a hashing algorithm work? | CryptoCompare.com

Secure Hash Standard (SHS)

What is the Secure Hash Algorithm 2 (SHA-2)? - Definition The Secure Hash Algorithm 2 (SHA-2) is a computer security cryptographic algorithm. It was created by the US National Security Agency (NSA) in collaboration with the National Institute of Science and Technology (NIST) as an enhancement to the SHA-1 algorithm.

SHA-1 - Wikipedia

Secure Hash Standard (SHS) The hash algorithms specified in this Standard are called secure because, for a given algorithm, it is computationally infeasible 1) to find a message that corresponds to a given message digest, or 2) to find two different messages that produce the same message digest. Descriptions of SHA-256, SHA-384, and SHA-512 there is a need for companion hash algorithms whic h pro vide similar lev els of enhanced securit y. SHA-256, describ ed in Chapter 2 of this pap er, is a 256-bit hash and is mean tto pro vide 128 bits of securit y against collision attac ks. SHA-512, in Chapter 3, is a 512-bit hash, and is mean t to pro vide 256 bits of securit y against Strengths and Weaknesses of Secure Cryptographic Hash and SHA-1 (Secure Hash Algorithm-1). Other cryptographic hash functions exist, such as SHA-256, SHA-512 and WHIRLPOOL. This paper will primarily be an analysis of the weaknesses of the MD5/SHA-1 algorithms and include notes on the theoretical security gain from common security practices and from switching to a more secure cryptographic hash SHA-1 Hash - GeeksforGeeks
