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.

Apr 5, 2024 · 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.

Jan 4, 2017 · 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 …

Jul 15, 2025 · SHA is an important aspect of cryptographic algorithms as it guarantees integrity when it comes to information. SHA1 and SHA2 are the most commonly used hashing algorithms in security …

SHA stands for Secure Hash Algorithm and is a cryptographic function for comparing unique checksums ("hashes"). SHA encryption does not allow any inference of the original string, as the encrypted text …

While it is still theoretically possible, modern SHA versions (such SHA-256 and SHA-3) are meant to reduce the probability of two different inputs producing the same hash value (a collision).
