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-256 hash function. Smart contracts use 256- or 257-bit integers; 256-bit words for the Ethereum Virtual Machine. "We realize that a 257 bits byte is quite unusual, but for smart contracts it is ok to have at least 256 bits numbers. The leading VM for smart contracts, Ethereum VM, introduced this practice and other blockchain VMs followed." [8]
Store random bytes to ES:[rDI], and increment ES:rDI accordingly. XSTORE will store currently-available bytes, which may be from 0 to 8 bytes. REP XSTORE and REP XRNG2 will write the number of random bytes specified by rCX, waiting for the random number generator when needed. [b] EDX specifies a "quality factor". [c] Nehemiah (stepping 3) REP ...

Las Cruces City Council took another step toward its goal of cutting into the 5,600 affordable housing rental unit shortfall by 2025. Council members approved a $6 million pre-commitment to help ...
Las Crucens can order a family meal to bring home at these local spots: Albertsons While a boneless rotisserie dinner begins at $70, there are options for ham and prime rib dinners.
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 woes of Greg Focker aren't over just yet. Ben Stiller, Robert De Niro, Teri Polo, and Blythe Danner are in early talks to return for a fourth Meet the Parents movie, nearly 15 years after they ...
