SHA-3 is a cryptographic hash algorithm that is the latest in the Secure Hash Algorithm series. It was released in 2015 and is the first cryptographic hash algorithm not based on the Merkle-Damgard construction.
SHA-3 is a cryptographic hash algorithm developed by the National Institute of Standards and Technology (NIST) as a successor to the Secure Hash Algorithm 2 (SHA-2). SHA-3 is a family of cryptographic hash functions that are designed to be more secure than SHA-2. It is designed to be resistant to attacks that have been successful against SHA-2, such as length extension attacks.
SHA-3 is a cryptographic hash algorithm that is designed to be more secure than SHA-2. It is a family of cryptographic hash functions that are designed to be resistant to attacks that have been successful against SHA-2, such as length extension attacks. SHA-3 is based on the Keccak algorithm, which was designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche. The Keccak algorithm is a sponge construction, which is a type of cryptographic primitive that can be used to construct a cryptographic hash function.
SHA-3 is designed to be more secure than SHA-2 by using a larger hash size and a different design. SHA-3 uses a larger hash size than SHA-2, which makes it more resistant to brute force attacks. Additionally, SHA-3 uses a different design than SHA-2, which makes it more resistant to length extension attacks.
SHA-3 is used in a variety of applications, including digital signatures, message authentication codes, and key derivation functions. It is also used in the Transport Layer Security (TLS) protocol, which is used to secure web communications. Additionally, SHA-3 is used in the Internet Key Exchange (IKE) protocol, which is used to securely exchange keys between two parties.
Overall, SHA-3 is a cryptographic hash algorithm that is designed to be more secure than SHA-2. It is a family of cryptographic hash functions that are designed to be resistant to attacks that have been successful against SHA-2, such as length extension attacks. SHA-3 is used in a variety of applications, including digital signatures, message authentication codes, and key derivation functions.
