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. These were also designed by the NSA. SHA-3 : A hash function formerly called Keccak , chosen in 2012 after a public competition among non-NSA designers.

SHA-2 basically consists of two hash algorithms: SHA-256 and SHA-512. SHA-224 is a variant of SHA-256 with different starting values and truncated output. SHA-384 and the lesser-known SHA-512/224 and SHA-512/256 are all variants of SHA-512. SHA-512 is more secure than SHA-256 and is commonly faster than SHA-256 on 64-bit machines such as AMD64.
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.
The encoding is equivalent to "MD5" MD5 hashing function replaced with SHA-256 and SHA-512-256. However, as of July 2021, none of popular browsers, including Firefox [2] and Chrome, [3] SHA-256 as the hash function. As of October 2021, Firefox 93 [4] officially supports "SHA-256" and "SHA-256-sess" algorithms for digest authentication.
The code CSS is non-XML syntax to define the style information for the various elements of the document that it styles. The language to structure a document (markup language) is a prelimit to CSS. A markup language, like HTML and less XUL, may define some primitive elements to style a document, for example <emphasis> to bold.
For example, the pad could be derived from the total length of the message. This kind of padding scheme is commonly applied to hash algorithms that use the Merkle–Damgård construction such as MD-5, SHA-1, and SHA-2 family such as SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, and SHA-512/256 [4]
