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.
For the exact SHA3-256 on x86-64, Bernstein measures 11.7–12.25 cpb depending on the CPU. [ 40 ] : 7 SHA-3 has been criticized for being slow on instruction set architectures (CPUs) which do not have instructions meant specially for computing Keccak functions faster – SHA2-512 is more than twice as fast as SHA3-512, and SHA-1 is more than ...
Windows Terminal is a multi-tabbed terminal emulator developed by Microsoft for Windows 10 and later [4] as a replacement for Windows Console. [5] It can run any command-line app in a separate tab. It is preconfigured to run Command Prompt , PowerShell , WSL and Azure Cloud Shell Connector, [ 6 ] [ 7 ] and can also connect to SSH by manually ...

sha1sum is a computer program that calculates and verifies SHA-1 hashes.It is commonly used to verify the integrity of files. It (or a variant) is installed by default on most Linux distributions.
It had a proprietary code base until 2015, but was then released as open source software. Versions are available for Linux, macOS, and Windows. Examples of hashcat-supported hashing algorithms are LM hashes, MD4, MD5, SHA-family and Unix Crypt formats as well as algorithms used in MySQL and Cisco PIX.
As of 2017, collisions but not preimages can be found in MD5 and SHA-1. The future is therefore likely to bring increasing use of newer hash functions such as SHA-256. However, fingerprints based on SHA-256 and other hash functions with long output lengths are more likely to be truncated than (relatively short) MD5 or SHA-1 fingerprints.
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.
