Netpgp
netpgp is a BSD licensed project based on the OpenPGP SDK which provides signing, verification, encryption, and decryption of files. It also comes with the netpgpkeys tool for key management. Netpgp is a higher level wrapper and improvement upon the OpenPGP SDK library written by Ben Laurie and Rachel Willmer. The public api of OpenPGP SDK is hidden exposing a simple interface for encryption and decryption as well as generating and verifying digital signatures. netpgp was included in the NetBSD distribution in May 2009 and in MidnightBSD MidnightBSD is a free Unix, desktop-oriented operating system originally forked from FreeBSD 6.1, and periodically updated with code and drivers from later FreeBSD releases.

Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Software
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program.Selling Free Software (gnu.org) Computer programs are deemed "free" if they give end-users (not just the developer) ultimate control over the software and, subsequently, over their devices. The right to study and modify a computer program entails that |
BSD License
BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software. This is in contrast to copyleft licenses, which have share-alike requirements. The original BSD license was used for its namesake, the Berkeley Software Distribution (BSD), a Unix-like operating system. The original version has since been revised, and its descendants are referred to as modified BSD licenses. BSD is both a license and a class of license (generally referred to as BSD-like). The modified BSD license (in wide use today) is very similar to the license originally used for the BSD version of Unix. The BSD license is a simple license that merely requires that all code retain the BSD license notice if redistributed in source code format, or reproduce the notice if redistributed in binary format. The BSD license (unlike some other licenses e.g. GPL) does not require that source code be distributed at all. Terms In addition t ...

OpenPGP
Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications. Phil Zimmermann developed PGP in 1991. PGP and similar software follow the OpenPGP, an open standard of PGP encryption software, standard (RFC 4880) for encrypting and decrypting data. Design PGP encryption uses a serial combination of hashing, data compression, symmetric-key cryptography, and finally public-key cryptography; each step uses one of several supported algorithms. Each public key is bound to a username or an e-mail address. The first version of this system was generally known as a web of trust to contrast with the X.509 system, which uses a hierarchical approach based on certificate authority and which was added to PGP implementations later. Current versions of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ben Laurie
Ben Laurie is an English software engineer. He is currently the Director of Security at The Bunker Secure Hosting. Laurie wrote Apache-SSL, the basis of most SSL-enabled versions of the Apache HTTP Server. He developed the MUD ''Gods'', which was innovative in including online creation in its endgame. Laurie also has written several articles, papers and books, and is interested in ideal knots and their applications. Laurie was a member of WikiLeaks' Advisory Board. According to Laurie, he had little involvement with WikiLeaks, and didn't know who ran the site other than Julian Assange Julian Paul Assange ( ; Hawkins; born 3 July 1971) is an Australian editor, publisher, and activist who founded WikiLeaks in 2006.

Rachel Willmer
Rachel () was a Biblical figure, the favorite of Jacob's two wives, and the mother of Joseph and Benjamin, two of the twelve progenitors of the tribes of Israel. Rachel's father was Laban. Her older sister was Leah, Jacob's first wife. Her aunt Rebecca was Jacob's mother. After Leah conceived again, Rachel was finally blessed with a son, Joseph, who would become Jacob's favorite child. Children Rachel's son Joseph was destined to be the leader of Israel's tribes between exile and nationhood. This role is exemplified in the Biblical story of Joseph, who prepared the way in Egypt for his family's exile there. After Joseph's birth, Jacob decided to return to the land of Canaan with his family. Fearing that Laban would deter him, he fled with his two wives, Leah and Rachel, and twelve children without informing his father-in-law. Laban pursued him and accused him of stealing his idols. Indeed, Rachel had taken her father's idols, hidden them inside her camel's seat cushion, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NetBSD
NetBSD is a free and open-source Unix operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems. The NetBSD project focuses on code clarity, careful design, and portability across many computer architectures. Its source code is publicly available and permissively licensed. History NetBSD was originally derived from the 4.3BSD-Reno release of the Berkeley Software Distribution from the Computer Systems Research Group of the University of California, Berkeley, via their Net/2 source code release and the 386BSD project. The NetBSD project began as a result of frustration within the 386BSD developer community with the pace and direction of the operating system's development. The four founders of the NetBSD project, Chris Demetriou, Theo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MidnightBSD
MidnightBSD is a free Unix, desktop-oriented operating system originally forked from FreeBSD 6.1, and periodically updated with code and drivers from later FreeBSD releases. Its default desktop environment, Xfce, is a lightweight user friendly desktop experience. History and development MidnightBSD began as a fork from FreeBSD in 2005. The founder of the project, Lucas Holt, wished to create a BSD derived desktop operating system. He was familiar with several live CD projects, but not the work on TrueOS or DesktopBSD. At the same time, he also had an interest in GNUstep. The two ideas were folded into a plan to create a user friendly desktop environment. MidnightBSD 0.1 was released based on the efforts of Lucas Holt, Caryn Holt, D. Adam Karim, Phil Pereira of bsdnexus, and Christian Reinhardt. This release features a modified version of the FreeBSD ports system. The ports system evolved into "mports" which includes fake support, generation of packages before installation, ...

Cryptographic Software
Encryption software is software that uses cryptography to prevent unauthorized access to digital information. Cryptography is used to protect digital information on computers as well as the digital information that is sent to other computers over the Internet. Classification There are many software products which provide encryption. Software encryption uses a cipher to obscure the content into ciphertext. One way to classify this type of software is the type of cipher used. Ciphers can be divided into two categories: public key ciphers (also known as asymmetric ciphers), and symmetric key ciphers. Encryption software can be based on either public key or symmetric key encryption. Another way to classify software encryption is to categorize its purpose. Using this approach, software encryption may be classified into software which encrypts "data in transit" and software which encrypts " data at rest". Data in transit generally uses public key ciphers, and data at rest generally uses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
