Intel SHA Extensions are a set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013. [ 1 ] Instructions for SHA-512 was introduced in Arrow Lake and Lunar Lake in 2024.
If it sounds like actors on your TV are speaking in whispers, there's a way to fix it to make your TV audio sound better. The CyberGuy has several tips.
It may perform some signal processing, such as upconverting video into a higher-resolution format, or splitting out the audio portion of the signal. Repeaters have HDMI inputs and outputs. Examples include home theater audio-visual receivers that separate and amplify the audio signal, while re-transmitting the video for display on a TV.
SHA-3 instances are drop-in replacements for SHA-2, intended to have identical security properties. SHAKE will generate as many bits from its sponge as requested, thus being extendable-output functions (XOFs). For example, SHAKE128(M, 256) can be used as a hash function with a 256 character bitstream with 128-bit security strength.
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.
The wide-pipe hash construction. The intermediate chaining values have been doubled. Due to several structural weaknesses of Merkle–Damgård construction, especially the length extension problem and multicollision attacks, Stefan Lucks proposed the use of the wide-pipe hash [11] instead of Merkle–Damgård construction.
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.
A vulnerability in the bootloader was fixed on Windows and various optimizations were made as well. The developers added support for SHA-256 to the system boot encryption option and also fixed a ShellExecute security issue. Linux and macOS users benefit from support for hard drives with sector sizes larger than 512.
