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.
It also allows the installation of MS-DOS or FreeDOS onto a flash drive as well as the creation of Windows To Go bootable media. [10] It supports formatting flash drives using FAT, FAT32, NTFS, exFAT, UDF and ReFS filesystems. [11] Rufus can also be used to compute the MD5, SHA-1 and SHA-256 hashes of the currently selected image.
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.

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.

Secure Hash Algorithm 2 (SHA-256 and SHA-384) — message digest Per CNSSP-15, the 256-bit elliptic curve (specified in FIPS 186-2), SHA-256, and AES with 128-bit keys are sufficient for protecting classified information up to the Secret level, while the 384-bit elliptic curve (specified in FIPS 186-2), SHA-384, and AES with 256-bit keys are ...
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 output size in bits is given by the extension to the "SHA" name, so SHA-224 has an output size of 224 bits (28 bytes); SHA-256, 32 bytes; SHA-384, 48 ...
