In the 1990s, several freeware and other proprietary tools (both hardware and software) were created to allow investigations to take place without modifying media. This first set of tools mainly focused on computer forensics , although in recent years similar tools have evolved for the field of mobile device forensics. [ 1 ]
Hardware-based encryption is the use of computer hardware to assist software, or sometimes replace software, in the process of data encryption. Typically, this is implemented as part of the processor 's instruction set.

A device's hardware ID, which is a cryptographic hash function specified by the device's vendor, can also be queried to construct a fingerprint. [ 42 ] : 109,114 Mitigation methods for browser fingerprinting
A SHA instruction set is a set of extensions to the x86 and ARM instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013 by Intel. [1] Instructions for SHA-512 was introduced in Arrow Lake and Lunar Lake in 2024.
The system automatically uses hardware random number generators (such as those provided on some Intel PCI hubs) if they are available, through the OpenBSD Cryptographic Framework. [23] [24] /dev/arandom was removed in OpenBSD 6.3 (April 15, 2018). [25] NetBSD's implementation of the legacy arc4random() API has been switched over to ChaCha20 as ...
The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA". It was ...
Furthermore, given some hash value, it is typically infeasible to find some input data (other than the one given) that will yield the same hash value. If an attacker can change not only the message but also the hash value, then a keyed hash or message authentication code (MAC) can be used for additional security. Without knowing the key, it is ...
