RIPEMD (RIPE Message Digest) is a family of cryptographic hash functions developed in 1992 (the original RIPEMD) and 1996 (other variants). There are five functions in the family: RIPEMD, RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320, of which RIPEMD-160 is the most common.
Figure 1. One MD5 operation. MD5 consists of 64 of these operations, grouped in four rounds of 16 operations. F is a nonlinear function; one function is used in each round. M i denotes a 32-bit block of the message input, and K i denotes a 32-bit constant, different for each operation. <<< s denotes a left bit rotation by s places; s varies for ...
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.
The Digest, formerly published as The English and Empire Digest, is a digest of case law. It is the "major modern work" of this kind. It is the "major modern work" of this kind. Its coverage is "wide" but incomplete, and it can be "complicated to use" if the user does not understand how the editions overlap. [ 1 ]
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.
Specialty subject digests exist, such as the Education Law Digest, and the Social Security Digest. For nationwide research, about once a month, West publishes a General Digest volume, which incorporates classified digest notes from all reporters of the West National Reporter System. These are then cumulated into a Decennial Digest. Decennial ...

AOHell was the first of what would become thousands of programs designed for hackers created for use with AOL. In 1994, seventeen year old hacker Koceilah Rekouche, from Pittsburgh, PA, known online as "Da Chronic", [1] [2] used Visual Basic to create a toolkit that provided a new DLL for the AOL client, a credit card number generator, email bomber, IM bomber, and a basic set of instructions.
