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 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. [3] [4] They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.
Honda Civic Country. The wheelbase now measured 2,250 mm (88.6 in) for the hatchback (the fastback sedan was no longer available) and 2,320 mm (91.3 in) for the wagon, 3-box design sedan, as well as the later five-door hatchback. The 1300 or 1500 cc Civic engines came in cross flow and CVCC design depending on the market they were sold in. In ...
The Asia-Pacific-market Civic is a rebadged Acura; Honda Japan claimed the company chose the Canadian-designed Acura CSX as the template for the Asia-Pacific Civic. [ 27 ] [ 28 ] In Canada, the Acura CSX has features and options not available to American Civics, such as a 2.0 L DOHC i-VTEC engine rated at 155 hp (116 kW), chrome door handles ...
In cryptography, security level is a measure of the strength that a cryptographic primitive — such as a cipher or hash function — achieves. Security level is usually expressed as a number of "bits of security" (also security strength), [1] where n-bit security means that the attacker would have to perform 2 n operations to break it, [2] but other methods have been proposed that more ...
