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.
Pidgin is a free and open-source multi-platform instant messaging client, based on a library named libpurple that has support for many instant messaging protocols, allowing the user to simultaneously log in to various services from a single application, with a single interface for both popular and obsolete protocols, thus avoiding the hassle of having to deal with a new software for each device and protocol.
In cryptography, Lucifer was the name given to several of the earliest civilian block ciphers, developed by Horst Feistel and his colleagues at IBM. Lucifer was a direct precursor to the Data Encryption Standard. One version, alternatively named DTD-1, saw commercial use in the 1970s for electronic banking.
In cryptography, the Zimmermann–Sassaman key-signing protocol is a protocol to speed up the public key fingerprint verification part of a key signing party. It requires some work before the event.
In public-key cryptography, a key signing party is an event at which people present their public keys to others in person, who, if they are confident the key actually belongs to the person who claims it, digitally sign the certificate containing that public key and the person's name, etc. Key signing parties are common within the PGP and GNU Privacy Guard community, as the PGP public key infrastructure does not depend on a central key certifying authority, but to a distributed web of trust approach. Key signing parties are a way to strengthen the web of trust. Participants at a key signing party are expected to present adequate identity documents.
In computer security, a key server is a computer that receives and then serves existing cryptographic keys to users or other programs. The users' programs can be running on the same network as the key server or on another networked computer.
A keychain is a small ring or chain of metal to which several keys can be attached. The length of a keychain allows an item to be used more easily than if connected directly to a keyring. Some keychains allow one or both ends the ability to rotate, keeping the keychain from becoming twisted, while the item is being used.
A key generator is a protocol or algorithm that is used in many cryptographic protocols to generate a sequence with many pseudo-random characteristics. This sequence is used as an encryption key at one end of communication, and as a decryption key at the other. One can implement a key generator in a system that aims to generate, distribute, and authenticate keys in a way that without the private key, one cannot access the information in the public end.
Personal data, also known as personal information or personally identifiable information (PII), is any information related to an identifiable person.
Seahorse is a GNOME front-end application for managing passwords, PGP and SSH keys. Seahorse integrates with a number of apps including Nautilus file manager, Epiphany browser and Evolution e-mail suite. It has HKP and LDAP key server support.
Secure Shell (SSH) is a protocol allowing secure remote login to a computer on a network using public-key cryptography. SSH client programs typically run for the duration of a remote login session and are configured to look for the user's private key in a file in the user's home directory. For added security, it is common to store the private key in an encrypted form, where the encryption key is computed from a passphrase that the user has memorized. Because typing the passphrase can be tedious, many users would prefer to enter it just once per local login session. The most secure place to store the unencrypted key is in program memory, and in Unix-like operating systems, memory is normally associated with a process. A normal SSH client process cannot be used to store the unencrypted key because SSH client processes only last the duration of a remote login session. Therefore, users run a program called ssh-agent that runs beyond the duration of a local login session, stores unencrypted keys in memory, and communicates with SSH clients using a Unix domain socket.
A keyfile is a file on a computer which contains encryption or license keys.
GNOME Keyring is a software application designed to store security credentials such as usernames, passwords, and keys, together with a small amount of relevant metadata. The sensitive data is encrypted and stored in a keyring file in the user's home directory. The default keyring uses the login password for encryption, so users don't need to remember another password.
Don Conway Wright is an American editorial cartoonist. He is the winner of two Pulitzer Prizes, having received one in 1966 and a second in 1980.
A multi-tool is a hand tool that combines several individual functions in a single unit. The smallest are credit-card or key sized units designed for carrying in a wallet or on a keyring, but others are designed to be carried in a trouser pocket or belt-mounted pouch.
KDE Wallet Manager (KWallet) is free and open-source password management software written in C++ for UNIX-style operating systems. KDE Wallet Manager runs on a Linux-based OS and Its main feature is storing encrypted passwords in KDE Wallets. The main feature of KDE wallet manager (KWallet) is to collect user's credentials such as passwords or IDs and encrypt them through Blowfish symmetric block cipher algorithm or GNU Privacy Guard encryption.
KEYY is a Christian radio station licensed to Provo, Utah, United States. The station is broadcasting via a translator on 91.3 FM in Provo as well. The station is owned by Biblical Ministries Worldwide, a Christian organization.
A Java KeyStore (JKS) is a repository of security certificates – either authorization certificates or public key certificates – plus corresponding private keys, used for instance in TLS encryption.
The Temporary Contact Numbers Protocol, or TCN Protocol, is an open source, decentralized, anonymous exposure alert protocol developed by Covid Watch in response to the COVID-19 pandemic. The Covid Watch team, started as an independent research collaboration between Stanford University and the University of Waterloo was the first in the world to publish a white paper, develop, and open source fully anonymous Bluetooth exposure alert technology in collaboration with CoEpi after writing a blog post on the topic in early March.
The California Privacy Rights Act of 2020 (CPRA), also known as Proposition 24, is a California ballot proposition that was approved by a majority of voters after appearing on the ballot for the general election on November 3, 2020. This proposition expands California's consumer privacy law and builds upon the California Consumer Privacy Act (CCPA) of 2018, which established a foundation for consumer privacy regulations.
