Key (cryptography)

In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a key, the algorithm would produce no useful result. In encryption, a key specifies the particular transformation of plaintext into ciphertext, or vice versa during decryption. Keys are also used in other cryptographic algorithms, such as digital signature schemes and message authentication codes.

Need for secrecy

In designing security systems, it is wise to assume that the details of the cryptographic algorithm are already available to the attacker. This is known as Kerckhoffs' principle — "only secrecy of the key provides security", or, reformulated as Shannon's maxim, "the enemy knows the system". The history of cryptography provides evidence that it can be difficult to keep the details of a widely used algorithm secret (see security through obscurity). A key is often easier to protect (it's typically a small piece of information) than an encryption algorithm, and easier to change if compromised. Thus, the security of an encryption system in most cases relies on some key being kept secret.

Keynote (presentation software)

Keynote is a presentation software application developed as a part of the iWork productivity suite by Apple Inc. Keynote 6.0 was announced on October 23, 2013 and is the most recent version for the Mac. On January 27, 2010, Apple announced a new version of Keynote for iPad with an all new touch interface.

History

Keynote began as a computer program for Apple CEO Steve Jobs to use in creating the presentations for Macworld Conference and Expo and other Apple keynote events. Prior to using Keynote, Jobs had used Concurrence, from Lighthouse Design, a similar product which ran on the NeXTSTEP and OpenStep platforms.

The program was first sold publicly as Keynote 1.0 in 2003, competing against existing presentation software, most notably Microsoft PowerPoint.

In 2005 Apple began selling Keynote 2.0 in conjunction with Pages, a new word processing and page layout application, in a software package called iWork. At the Macworld Conference & Expo 2006, Apple released iWork '06 with updated versions of Keynote 3.0 and Pages 2.0. In addition to official HD compatibility, Keynote 3 added new features, including group scaling, 3D charts, multi-column text boxes, auto bullets in any text field, image adjustments, and free form masking tools. In addition, Keynote features three-dimensional transitions, such as a rotating cube or a simple flip of the slide.

Database index

A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Indexes can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records.

An index is a copy of select columns of data from a table that can be searched very efficiently that also includes a low-level disk block address or direct link to the complete row of data it was copied from. Some databases extend the power of indexing by letting developers create indices on functions or expressions. For example, an index could be created on upper(last_name), which would only store the upper case versions of the last_name field in the index. Another option sometimes supported is the use of partial indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.

Chart

A chart, also called a graph, is a graphical representation of data, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart". A chart can represent tabular numeric data, functions or some kinds of qualitative structure and provides different info.

The term "chart" as a graphical representation of data has multiple meanings:

A data chart is a type of diagram or graph, that organizes and represents a set of numerical or qualitative data.

Maps that are adorned with extra information (map surround) for a specific purpose are often known as charts, such as a nautical chart or aeronautical chart, typically spread over several map sheets.

Other domain specific constructs are sometimes called charts, such as the chord chart in music notation or a record chart for album popularity.

Charts are often used to ease understanding of large quantities of data and the relationships between parts of the data. Charts can usually be read more quickly than the raw data that they are produced from. They are used in a wide variety of fields, and can be created by hand (often on graph paper) or by computer using a charting application. Certain types of charts are more useful for presenting a given data set than others. For example, data that presents percentages in different groups (such as "satisfied, not satisfied, unsure") are often displayed in a pie chart, but may be more easily understood when presented in a horizontal bar chart. On the other hand, data that represents numbers that change over a period of time (such as "annual revenue from 1990 to 2000") might be best shown as a line chart.

Symmetric Key Cryptography relies on a single key for encryption and decryption of information. Both the sender and receiver of the message need to have a pre-shared secret key that they will use to convert the plaintext into ciphertext and vice versa. ➡️ About Post Graduate Program In Full Stack Web Development This program will give you the foundation for building full-stack web apps using the Java programming language.

Asymmetric Encryption requires two keys: a Public key and a Private key. These keys can be used to perform Encryption and Message Signing. Encryption provides Confidentiality, and Message Signatures provides Integrity and Authentication. This lesson is a free sample lesson from the the greatest TLS and SSL training course ever created. No instructor rambling on about pointless stories. No slides with massive walls of text. No time wasting. Only simple, effective, and precise explanations. Complimented with practical illustrations and visuals. 🔐 More details about the course: https://classes.pracnet.net/courses/practical-tls 🏢 Do you configure or troubleshoot TLS/SSL for work? If so, I'm willing to bet your employer would happily pay for this SSL training. Reach out if you'd like to coordinate an introduction for a bulk license purchase with your company. I'm happy to provide a generous referral bonus =) 💬 Join Practical Networking Discord https://discord.com/invite/yrexngJ 🖧 Want to learn how how data moves through a network? https://www.youtube.com/playlist?list=PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi Since you've made it to the bottom of the Description, here's a $100 off coupon code you can use on the full course =) YT100

Key (cryptography)

In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a key, the algorithm would produce no useful result. In encryption, a key specifies the particular transformation of plaintext into ciphertext, or vice versa during decryption. Keys are also used in other cryptographic algorithms, such as digital signature schemes and message authentication codes.

Need for secrecy

In designing security systems, it is wise to assume that the details of the cryptographic algorithm are already available to the attacker. This is known as Kerckhoffs' principle — "only secrecy of the key provides security", or, reformulated as Shannon's maxim, "the enemy knows the system". The history of cryptography provides evidence that it can be difficult to keep the details of a widely used algorithm secret (see security through obscurity). A key is often easier to protect (it's typically a small piece of information) than an encryption algorithm, and easier to change if compromised. Thus, the security of an encryption system in most cases relies on some key being kept secret.
