Enigmail
Enigmail is a data encryption and decryption extension for Mozilla Thunderbird and the Postbox that provides OpenPGP public key e-mail encryption and signing. Enigmail works under Microsoft Windows, Unix-like, and Mac OS X operating systems. Enigmail can operate with other mail clients compatible with PGP/MIME and inline PGP such as: Microsoft Outlook with Gpg4win package installed, Gnome Evolution, KMail, Claws Mail, Gnus, Mutt. Its cryptographic functionality is handled by GNU Privacy Guard. In their default configuration, Thunderbird and SeaMonkey provide e-mail encryption and signing using S/MIME, which relies on X.509 keys provided by a centralised certificate authority. Enigmail adds an alternative mechanism where cooperating users can instead use keys provided by a web of trust, which relies on multiple users to endorse the authenticity of the sender's and recipient's credentials. In principle this enhances security, since it does not rely on a centralised entity which mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pretty Easy Privacy
pretty Easy privacy (p≡p or pEp) is a pluggable data encryption and verification system, which provides automatic cryptographic key management through a set of libraries (providing p≡p adapters for application developers' used programming languages and development environments) for written digital communications. Its main goal is to make end-to-end encryption the default in written digital communications for all users in the easiest way possible and on the channels they already make use of, including e-mails, SMS, or other types of messages. It exists as a plugin for Microsoft Outlook and Mozilla Thunderbird as well as a mobile app for Android and iOS. p≡p also works under Microsoft Windows, Unix-like and, Mac OS X operating systems. Its cryptographic functionality is handled by an open-source p≡p engine relying on already existing cryptographic implementations in software like GnuPG, a modified version of netpgp (used only in iOS), and (as of p≡p v2.0) GNUnet.

Autocrypt
Autocrypt is a cryptographic protocol A security protocol (cryptographic protocol or encryption protocol) is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods, often as sequences of cryptographic primitives. A protocol describe ... for email clients aiming to simplify key exchange and enabling encryption. Version 1.0 of thAutocrypt specificationwas released in December 2017 and makes no attempt to protect against MITM attacks. It is implemented on top of OpenPGP replacing its complex key management by fully automated unsecured exchange of Key (cryptography), cryptographic keys between peers . Method Autocrypt-capable email clients transparently negotiate encryption capabilities and preferences and exchange keys between users alongside sending regular emails. This is done by including the key material and encryption preferences in the header of each email, which allows encrypting any message to a contact who has prev ...

Mozilla Thunderbird
Mozilla Thunderbird is a free and open-source cross-platform email client, personal information manager, news client, RSS and chat client developed by the Mozilla Foundation and operated by subsidiary MZLA Technologies Corporation. The project strategy was originally modeled after that of Mozilla's Firefox web browser. Features Thunderbird is an email, newsgroup, news feed, and chat (XMPP/IRC) client with personal information manager (PIM) functionality, inbuilt since version 78.0 and previously available from the Lightning calendar extension. Additional features are available from extensions. Message management Thunderbird manages multiple email, newsgroup, and news feed accounts and supports multiple identities within accounts. Features such as quick search, saved search folders ("virtual folders"), advanced message filtering, message grouping, and tags help manage and find messages. On Linux-based systems, system mail (movemail) accounts were supported until version 91.0. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU Privacy Guard
GNU Privacy Guard (GnuPG or GPG) is a free-software replacement for Symantec's PGP cryptographic software suite. The software is compliant with RFC 4880, the IETF standards-track specification of OpenPGP. Modern versions of PGP are interoperable with GnuPG and other OpenPGP-compliant systems. GnuPG is part of the GNU Project and received major funding from the German government in 1999. Overview GnuPG is a hybrid-encryption software program because it uses a combination of conventional symmetric-key cryptography for speed, and public-key cryptography for ease of secure key exchange, typically by using the recipient's public key to encrypt a session key which is used only once. This mode of operation is part of the OpenPGP standard and has been part of PGP from its first version. The GnuPG 1.x series uses an integrated cryptographic library, while the GnuPG 2.x series replaces this with Libgcrypt. GnuPG encrypts messages using asymmetric key pairs individually g ...

Mozilla Public License
The Mozilla Public License (MPL) is a free and open-source weak copyleft license for most Mozilla Foundation software such as Firefox and Thunderbird The MPL license is developed and maintained by Mozilla, which seeks to balance the concerns of both open-source and proprietary developers; it is distinguished from others as a middle ground between the permissive software BSD-style licenses and the General Public License. So under the terms of the MPL, it allows the integration of MPL-licensed code into proprietary codebases, but only on condition those components remain accessible. MPL has been used by others, such as Adobe to license their Flex product line, and The Document Foundation to license LibreOffice 4.0 (also on LGPL 3+). Version 1.1 was adapted by several projects to form derivative licenses like Sun Microsystems' Common Development and Distribution License. It has undergone two revisions: the minor update 1.1, and a major update version 2.0 nearing the goals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutt (email Client)
Mutt is a text-based email client for Unix-like systems. It was originally written by Michael Elkins in 1995 and released under the GNU General Public License version 2 or any later version. The Mutt slogan is "''All mail clients suck. This one just sucks less.''" Operation Mutt supports most mail storing formats (notably both mbox and Maildir) and protocols (POP3, IMAP, etc.). It also includes MIME support, notably full PGP/ GPG and S/MIME integration. Mutt was originally designed as a Mail User Agent (MUA) and relied on locally accessible mailbox and sendmail infrastructure. According to the Mutt homepage "though written from scratch, Mutt's initial interface was based largely on the ELM mail client". New to Mutt were message scoring and threading capabilities. Support for fetching and sending email via various protocols such as POP3, IMAP and SMTP was added later. However, Mutt still relies on external tools for composing and filtering messages. Mutt has hundreds of config ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

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] |
Temple In Jerusalem
The Temple in Jerusalem, or alternatively the Holy Temple (; , ), refers to the two now-destroyed religious structures that served as the central places of worship for Israelites and Jews on the modern-day Temple Mount in the Old City of Jerusalem. According to the Hebrew Bible, the Solomon's Temple, First Temple was built in the 10th century BCE, during the reign of Solomon over the Kingdom of Israel (united monarchy), United Kingdom of Israel. It stood until , when it was destroyed during the Siege of Jerusalem (587 BC), Babylonian siege of Jerusalem. Almost a century later, the First Temple was replaced by the Second Temple, which was built after the Neo-Babylonian Empire was conquered by the Achaemenid Empire, Achaemenid Persian Empire. While the Second Temple stood for a longer period of time than the First Temple, it was likewise destroyed during the Siege of Jerusalem (70 CE), Roman siege of Jerusalem in 70 CE. Projects to build the hypothetical "Third Temple" have not co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-source Software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2008 report by the Standish Group stated that adoption of open-source software models has resulted in savings of about $60 billion per year for consumers. Open source code can be used for studying and allows capable end users to adapt software to their personal needs in a similar way user scripts an ...
