Code Signing
Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. The process employs the use of a cryptographic hash to validate authenticity and integrity. Code signing was invented in 1995 by Michael Doyle, as part of the Eolas WebWish browser plug-in, which enabled the use of public-key cryptography to sign downloadable Web app program code using a secret key, so the plug-in code interpreter could then use the corresponding public key to authenticate the code before allowing it access to the code interpreter's APIs. Code signing can provide several valuable features. The most common use of code signing is to provide security when deploying; in some programming languages, it can also be used to help prevent namespace conflicts. Almost every code signing implementation will provide some sort of digital signature mechanism to verify the identity of the a ...

Digital Signatures And Law
Many states and legal jurisdictions have adopted legislation concerning the validity and effects of electronic signatures, including cryptographic digital signatures. Article 7 of the United Nations Commission on International Trade Law's ''Model Law on Electronic Commerce'' addresses electronic signatures, providing wording intended to harmonise legal provisions in their field in order to promote international trade, and the Commission's ''Model Law on Electronic Signatures'' (2001) is a strong influence in this field. Examples of legislation by state or jurisdiction include: ArgentinaLey Nº 25.506(B.O. 14/12/2001).(B.O. 20/12/2002).(B.O. 13/06/06).(B.O. 03/11/14). Bermuda eSignature technology and electronic document solutions Brazil- Brazilian law states that any digital document is valid for the law if it is certified by ICP-Brasil (the official Brazilian PKI) or if it is certified by another PKI and the concerned parties agree as to the validity of the document.

WHQL Testing
The Windows Hardware Certification program (formerly Windows Hardware Quality Labs Testing, WHQL Testing, or Windows Logo Testing) is Microsoft's testing process which involves running a series of tests on third-party device drivers, and then submitting the log files from these tests to Microsoft for review. The procedure may also include Microsoft running their own tests on a wide range of equipment, such as different hardware and different Microsoft Windows editions. Overview The WHQL project was started since Windows 95. Windows 2000 added support for WHQL signature checking. Products that pass the WHQL tests get to use a "Certified for Windows" logo aka "Designed for Windows" logo, which certifies that the hardware or software has had some share of testing by Microsoft to ensure compatibility. The actual logo used depends on the version of Microsoft Windows. (In the past, Microsoft also awarded a similar logo as part of a different Software Certification program to apps ...

Random-access Memory
Random-access memory (RAM; ) is a form of Computer memory, electronic computer memory that can be read and changed in any order, typically used to store working Data (computing), data and machine code. A random-access memory device allows data items to be read (computer), read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks and Magnetic tape data storage, magnetic tape), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. In today's technology, random-access memory takes the form of integrated circuit (IC) chips with MOSFET, MOS (metal–oxide–semiconductor) Memory cell (computing), memory cells. RAM is normally associated with Volatile memory, volatile types of memory where s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
App Store (iOS)
The App Store is an app marketplace developed and maintained by Apple, for mobile apps on its iOS and iPadOS operating systems. The store allows users to browse and download approved apps developed within Apple's iOS SDK. Apps can be downloaded on the iPhone, iPod Touch, or iPad, and some can be transferred to the Apple Watch smartwatch or 4th-generation or newer Apple TVs as extensions of iPhone apps. The App Store opened on July 10, 2008, with an initial 500 applications available. The number of apps peaked at around 2.2 million in 2017, but declined slightly over the next few years as Apple began a process to remove old or 32-bit apps. , the store features more than 1.8 million apps. While Apple touts the role of the App Store in creating new jobs in the "app economy" and claims to have paid over $155 billion to developers, the App Store has also attracted criticism from developers and government regulators that it operates a monopoly and that Apple's 30% cut of revenues ...

Trust On First Use
Trust on first use (TOFU), or trust upon first use (TUFU), is an authentication scheme used by client software which needs to establish a trust relationship with an unknown or not-yet-trusted endpoint. In a TOFU model, the client will try to look up the endpoint's identifier, usually either the public identity key of the endpoint, or the fingerprint of said identity key, in its local trust database. If no identifier exists yet for the endpoint, the client software will either prompt the user to confirm they have verified the purported identifier is authentic, or if manual verification is not assumed to be possible in the protocol, the client will simply trust the identifier which was given and record the trust relationship into its trust database. If in a subsequent connection a different identifier is received from the opposing endpoint, the client software will consider it to be untrusted. TOFU implementations In the SSH protocol, most client software (though not all) will, u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extended Validation
An Extended Validation (EV) Certificate is a certificate conforming to X.509 that proves the legal entity of the owner and is signed by a certificate authority key that can issue EV certificates. EV certificates can be used in the same manner as any other X.509 certificates, including securing web communications with HTTPS and signing software and documents. Unlike domain-validated certificates and organization-validation certificates, EV certificates can be issued only by a subset of certificate authorities (CAs) and require verification of the requesting entity's legal identity before certificate issuance. As of February 2021, all major web browsers (Google Chrome, Mozilla Firefox, Microsoft Edge and Apple Safari) have menus which show the EV status of the certificate and the verified legal identity of EV certificates. Mobile browsers typically display EV certificates the same way they do Domain Validation (DV) and Organization Validation (OV) certificates. Of the ten most po ...

Private Key
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. There are many kinds of public-key cryptosystems, with different security goals, including digital signature, Diffie–Hellman key exchange, public-key key encapsulation, and public-key encryption. Public key algorithms are fundamental security primitives in modern cryptosystems, including applications and protocols that offer assurance of the confidentiality and authenticity of electronic communications and data storage. They underpin numerous Internet standards, such as Transport Layer Security (TLS), SSH, S/MIME, and P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Key Infrastructure
A public key infrastructure (PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. The purpose of a PKI is to facilitate the secure electronic transfer of information for a range of network activities such as e-commerce, internet banking and confidential email. It is required for activities where simple passwords are an inadequate authentication method and more rigorous proof is required to confirm the identity of the parties involved in the communication and to validate the information being transferred. In cryptography, a PKI is an arrangement that ''binds'' public keys with respective identities of entities (like people and organizations). The binding is established through a process of registration and issuance of certificates at and by a certificate authority (CA). Depending on the assurance level of the binding, this may be carried out by an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
