A detached signature is a type of digital signature that is kept separate from its signed data, as opposed to bundled together into a single file.
This approach offers several advantages, such as preventing unauthorized modifications to the original data objects. However, there is a risk that the detached signature could become separated from its associated data, making the data inaccessible.
In cryptography, encryption is the process of transforming information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Despite its goal, encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor.
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions. Security of public-key cryptography depends on keeping the private key secret; the public key can be openly distributed without compromising security.
A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature on a message gives a recipient confidence that the message came from a sender known to the recipient.
S/MIME is a standard for public-key encryption and signing of MIME data. S/MIME is on an IETF standards track and defined in a number of documents, most importantly RFC 8551. It was originally developed by RSA Data Security, and the original specification used the IETF MIME specification with the de facto industry standard PKCS #7 secure message format. Change control to S/MIME has since been vested in the IETF, and the specification is now layered on Cryptographic Message Syntax (CMS), an IETF specification that is identical in most respects with PKCS #7. S/MIME functionality is built into the majority of modern email software and interoperates between them. Since it is built on CMS, MIME can also hold an advanced digital signature.
An electronic signature, or e-signature, is data that is logically associated with other data and which is used by the signatory to sign the associated data. This type of signature has the same legal standing as a handwritten signature as long as it adheres to the requirements of the specific regulation under which it was created.
XML Signature defines an XML syntax for digital signatures and is defined in the W3C recommendation XML Signature Syntax and Processing. Functionally, it has much in common with PKCS #7 but is more extensible and geared towards signing XML documents. It is used by various Web technologies such as SOAP, SAML, and others.
In computer programming, a function prototype is a declaration of a function that specifies the function's name and type signature, but omits the function body. While a function definition specifies how the function does what it does, a function prototype merely specifies its interface, i.e. what data types go in and come out of it. The term "function prototype" is particularly used in the context of the programming languages C and C++ where placing forward declarations of functions in header files allows for splitting a program into translation units, i.e. into parts that a compiler can separately translate into object files, to be combined by a linker into an executable or a library. The function declaration precedes the function definition, giving details of name, return type, and storage class along with other relevant attributes.
nohup is a POSIX command which means "no hang up". Its purpose is to execute a command such that it ignores the HUP (hangup) signal and therefore does not stop when the user logs out.
Kontact is a personal information manager and groupware software suite developed by KDE. It supports calendars, contacts, notes, to-do lists, news, and email. It offers a number of inter-changeable graphical UIs all built on top of a common core.
A single-family detached home, also called a single-detached dwelling,single-family residence (SFR) or separate house is a free-standing residential building. It is defined in opposition to a multi-family residential dwelling.
The scattered disc (or scattered disk) is a distant circumstellar disc in the Solar System that is sparsely populated by icy small Solar System bodies, which are a subset of the broader family of trans-Neptunian objects. The scattered-disc objects (SDOs) have orbital eccentricities ranging as high as 0.8, inclinations as high as 40°, and perihelia greater than 30 astronomical units (4.5×109 km; 2.8×109 mi). These extreme orbits are thought to be the result of gravitational "scattering" by the gas giants, and the objects continue to be subject to perturbation by the planet Neptune.
Munin is a free and open-source computer system monitoring, network monitoring, and infrastructure monitoring software application.
Lésigny is a commune in the Seine-et-Marne département in the Île-de-France region in the south-eastern suburbs of Paris, France. It is 20 km (12 mi) from Paris.
The Estonian identity card is a mandatory identity document for citizens of Estonia. In addition to regular identification of a person, an ID-card can also be used for establishing one's identity in electronic environment and for giving one's digital signature. Within Europe as well as French overseas territories, Georgia and Tunisia the Estonian ID-card can be used by the citizens of Estonia as a travel document.
IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony and Panasonic. It is most commonly known by the name FireWire (Apple), though other brand names exist such as i.LINK (Sony), and Lynx.
A card security code is a series of numbers that, in addition to the bank card number, is printed on a credit or debit card. The CSC is used as a security feature for card not present transactions, where a personal identification number (PIN) cannot be manually entered by the cardholder. It was instituted to reduce the incidence of credit card fraud. Unlike the card number, the CSC is deliberately not embossed, so that it is not read when using a mechanical credit card imprinter which will only pick up embossed numbers.
Salt is a Python-based, open-source software for event-driven IT automation, remote task execution, and configuration management. Supporting the "infrastructure as code" approach to data center system and network deployment and management, configuration automation, SecOps orchestration, vulnerability remediation, and hybrid cloud control.
Pro Football Focus is a sports analytics company that focuses on thorough analysis of the National Football League (NFL) and NCAA Division-I football in the United States. PFF produces 0–100 Player Grades and a range of advanced statistics for teams and players by watching, charting, and grading every player on every play in every game both at the NFL and FBS level.
Associated Signature Containers (ASiC) specifies the use of container structures to bind together one or more signed objects with either advanced electronic signatures or timestamp tokens into one single digital container.
Segregated Witness, or SegWit, is the name used for an implemented soft fork change in the transaction format of Bitcoin.
