The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: [5] SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256. SHA-256 and SHA-512 are hash functions whose digests are eight 32-bit and 64-bit words, respectively.

2017年1月4日 · SHA-2 family of hash algorithms: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, and SHA-512/256. NIST deprecated the use of SHA-1 in 2011 and disallowed its use for digital signatures at the end of 2013, based on both the Wang et. al attack and the potential for brute-force attack.

SHA-2: A family of two similar hash functions, with different block sizes, known as SHA-256 and SHA-512. They differ in the word size; SHA-256 uses 32-bit words where SHA-512 uses 64-bit words. There are also truncated versions of each standard, known as SHA-224, SHA-384, SHA-512/224 and SHA-512/256. These were also designed by the NSA.

SHA-2，名稱來自於安全散列演算法2（英語： Secure Hash Algorithm 2 ）的縮寫，是一種密碼雜湊函數演算法標準，由美國國家安全局研發 [3] ，由美國國家標準與技術研究院（NIST）在2001年發布。

The SHA-2 family offers robust hashing algorithms: SHA-256, SHA-384, and SHA-512. This blog post breaks down their key differences, including security levels and performance considerations.

2022年2月17日 · SHA-2 is a hash function that plays a critical role in much of our online security. Find out what it is, where it's used and how it works. This guide will cover the SHA-2 family of algorithms in broad terms. If you are looking for an in-depth dive into how the SHA-256 algorithm actually works, head over to our What is the SHA-2 algorithm? article.

SHA-2 is a family of cryptographic hash algorithms used to create message digest to verify the integrity of information (usually files). They are the current standard in cryptographic hash functions and have several applications, included digital signatures. SHA-2 is based on the Merkle-Damgård construction.

2025年1月1日 · The SHA (Secure Hash Algorithm) Family currently designates a family of six different hash functions: SHA-0, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 (National Institute of Standards and Technology (NIST) 1995; National Institute of Standards and Technology (NIST) 2002) published by the American National Institute of Standards and ...

The SHA (Secure Hash Algorithm) Family designates a family of six different hash functions: SHA-0, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 [7, 8]. They take variable length input messages and hash them to fixed-length outputs.

The SHA-2 (Secure Hash Algorithm 2) hash family is a group of cryptographic hash functions designed to provide secure and reliable data integrity verification.
