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.

2024年4月5日 · A secure hashing algorithm, or SHA, changes data by creating a hash digest unique to each plaintext message. The two main types of SHAs are SHA-1 and SHA-2.

2025年5月13日 · SHA stands for Secure Hash Algorithm, a cryptographic function developed to protect sensitive data. It takes an input message, such as a text, file, password, or any data input, and runs it …

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 …

SHA-256 and SHA-512 are SHA-2 algorithms using hash lengths of 256 and 512 bits respectively, and SHA-224 and SHA-384 are truncated versions. SHA-256 is the hash algorithm used in the...

Secure Hash Algorithms, also known as SHA, are a family of cryptographic functions designed to keep data secured. It works by transforming the data using a hash function: an algorithm that consists of …

Secure Hash Algorithm (SHA) is a family of cryptographic hash functions designed to ensure data integrity by producing unique hash values for different inputs. Understanding the functionality of …

The algorithms are collectively known as SHA-2, named after their digest lengths (in bits): SHA-256, SHA-384, and SHA-512. The algorithms were first published in 2001 in the draft FIPS PUB 180-2, at …

SHA-0: It was the name used for the original Secure Hashing Algorithm that was released in 1993. It was no longer used because it was not safe to use and was quickly replaced with SHA-1.

SHA-1 and SHA-2 are the hash algorithms required by law for use in certain U.S. government applications, including use within other cryptographic algorithms and protocols, for the protection of …
