md5sum is a computer program that calculates and verifies 128-bit MD5 hashes, as described in RFC 1321. The MD5 hash functions as a compact digital fingerprint of a file. The MD5 hash functions as a compact digital fingerprint of a file.
In 2012, according to Microsoft, the authors of the Flame malware used an MD5 collision to forge a Windows code-signing certificate. [ 33 ] MD5 uses the Merkle–Damgård construction , so if two prefixes with the same hash can be constructed, a common suffix can be added to both to make the collision more likely to be accepted as valid data by ...
The Calculator in non-LTSC editions of Windows 10 is a Universal Windows Platform app. In contrast, Windows 10 LTSC (which does not include universal Windows apps) includes the traditional calculator, but which is now named win32calc.exe. Both calculators provide the features of the traditional calculator included with Windows 7 and Windows 8.x ...
This is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the current data input matches the stored value of a previously computed checksum, there is a very high probability the data has not been accidentally altered or corrupted.

On Unix-like systems, similar functionality can be often obtained by combining find with hashing utilities such as md5sum, sha256sum or tthsum. md5deep exists for Windows and most Unix-based systems, including OS X. It is present in OS X's Fink, Homebrew and MacPorts projects. Binary packages exist for most free Unix systems.
Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser.This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.
A rainbow table is a precomputed table for caching the outputs of a cryptographic hash function, usually for cracking password hashes.Passwords are typically stored not in plain text form, but as hash values.
