A square is a regular quadrilateral with four equal sides and four right angles.

Blowfish is a symmetric-key block cipher, designed in 1993 by Bruce Schneier and included in many cipher suites and encryption products. Blowfish provides a good encryption rate in software, and no effective cryptanalysis of it has been found to date for smaller files. It is recommended Blowfish should not be used to encrypt files larger than 4GB in size, Twofish should be used instead.
Radical may refer to:
AAA, Triple A, or Triple-A is a three-letter initialism or abbreviation which may refer to:
In cryptography, a block cipher mode of operation is an algorithm that uses a block cipher to provide information security such as confidentiality or authenticity. A block cipher by itself is only suitable for the secure cryptographic transformation of one fixed-length group of bits called a block. A mode of operation describes how to repeatedly apply a cipher's single-block operation to securely transform amounts of data larger than a block.
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component. These drawings are linked together by a "master drawing." This "master drawing" is more commonly known as an assembly drawing. The assembly drawing gives the drawing numbers of the subsequent detailed components, quantities required, construction materials and possibly 3D images that can be used to locate individual items. Although mostly consisting of pictographic representations, abbreviations and symbols are used for brevity and additional textual explanations may also be provided to convey the necessary information.

In computer science and cryptography, Whirlpool is a cryptographic hash function. It was designed by Vincent Rijmen and Paulo S. L. M. Barreto, who first described it in 2000.
In cryptography, padding is any of a number of distinct practices which all include adding data to the beginning, middle, or end of a message prior to encryption. In classical cryptography, padding may include adding nonsense phrases to a message to obscure the fact that many messages end in predictable ways, e.g. sincerely yours.
Pathfinder, Path Finder or Pathfinders may refer to:
In industrial design, preferred numbers are standard guidelines for choosing exact product dimensions within a given set of constraints. Product developers must choose numerous lengths, distances, diameters, volumes, and other characteristic quantities. While all of these choices are constrained by considerations of functionality, usability, compatibility, safety or cost, there usually remains considerable leeway in the exact choice for many dimensions.
The CNS 11643 character set, also officially known as the Chinese Standard Interchange Code or CSIC, is officially the standard character set of Taiwan. Published and draft editions of CNS 11643 remain the source standards for Unicode reference glyphs for CJK Unified Ideographs submitted for use in Taiwan, and the character repertoire of CNS 11643 continues to be updated and used for administrative purposes in Taiwan.
When setting photoflash exposures, the guide number (GN) of photoflash devices is a measure photographers can use to calculate either the required f‑stop for any given flash-to-subject distance, or the required distance for any given f‑stop. To solve for either of these two variables, one merely divides a device's guide number by the other.
Lie-Nielsen Toolworks, Inc. is a family-owned business, established in 1981 and based in Warren, Maine. It manufactures a range of high quality hand tools, primarily for woodworking, based on traditional designs. It is best known for its hand planes. Thomas Lie-Nielsen is the founder and CEO of Lie-Nielsen Toolworks.
Cop or Cops commonly refers to a police officer.
The following outline is provided as an overview of and topical guide to cryptography:
A Speed Square, also generically called a rafter square, rafter angle square, and triangle square, is a multi-purpose triangular carpenters' tool used for marking out. Its functions encompass many of those offered by combination squares, try squares, and framing squares. Carpenters use it to make basic measurements and mark lines on dimensional lumber, and as a saw guide for short 45 and 90 degree cuts.
Square is a point-of-sale system for merchants with physical or online stores. Launched in 2009 by Block, Inc., it enables sellers to accept card payments and manage business operations. As of 2023, Square is the U.S. market leader in point-of-sale systems, serving 4 million sellers and processing $210bn annually.
