FTK is also associated with a standalone disk imaging program called FTK Imager. This tool saves an image of a hard disk in one file or in segments that may be later on reconstructed. It calculates MD5 and SHA1 hash values and can verify the integrity of the data imaged is consistent with the created forensic image. The forensic image can be ...
The data produced in the previous step is hashed with a cryptographic hash function such as SHA-1 or SHA-2. If desired, the hash function output can be truncated to provide a shorter, more convenient fingerprint. This process produces a short fingerprint which can be used to authenticate a much larger public key.
It was withdrawn by the NSA shortly after publication and was superseded by the revised version, published in 1995 in FIPS PUB 180-1 and commonly designated SHA-1. SHA-1 differs from SHA-0 only by a single bitwise rotation in the message schedule of its compression function. According to the NSA, this was done to correct a flaw in the original ...
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.
Collisions against the full SHA-1 algorithm can be produced using the shattered attack and the hash function should be considered broken. SHA-1 produces a hash digest of 160 bits (20 bytes). Documents may refer to SHA-1 as just "SHA", even though this may conflict with the other Secure Hash Algorithms such as SHA-0, SHA-2, and SHA-3.

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. The original SSE-based extensions added four instructions supporting SHA-1 and ...
To match a print, a fingerprint technician scans in the print in question, and computer algorithms are utilized to mark all minutia points, cores, and deltas detected on the print. In some systems, the technician is allowed to perform a review of the points that the software has detected, and submits the feature set to a one-to-many (1:N) search.
