Glossary

This glossary is provided for your information only, + and is not meant to be relied upon as a complete or authoritative description + of the terms defined below or of the privacy and/or security ramifications of + the technologies described.

Glossary

+ +

add-on

A piece of software that can be added to + &brandShortName; to change its appearance, behavior, or to add new features. + It can also change the language shown in the user interface. See also + extension, language + pack, plugin, and theme.

+ +

authentication

The use of a password, + certificate, personal identification number (PIN), or other information to + validate an identity over a computer network. See also + password-based authentication, + certificate-based + authentication, client + authentication, server + authentication.

+ +

bookmark

A stored web page + address (URL) that you can go to easily by clicking a + bookmark icon in the Personal Toolbar or + choosing the bookmark's name from the Bookmarks menu.

+ +

See certificate + authority (CA)

+ +

CA certificate

A certificate that + identifies a certificate authority. See also + certificate authority (CA), + subordinate CA, root + CA.

+ +

cache

A collection of web page copies stored + on your computer's hard disk or in its random-access memory (RAM). The + browser accumulates these copies as you browse the Web. When you click a link + or type a URL to fetch a particular web page for which the + cache already contains a copy, the browser compares the cached copy to the + original. If there have been no changes, the browser uses the cached copy + rather than refetching the original, saving processing and download + time.

+ +

caret browsing

A &brandShortName; feature that + allows you to navigate through text in Web pages and e-mail messages (or this + Help window) with a caret. Using your keyboard, you can navigate and select + text like you do in a text editor. You can turn caret browsing mode on or off + by pressing the F7 key. Caret browsing mode can also be enabled or + disabled in Advanced Preferences - Keyboard Navigation.

+ +

certificate

The digital equivalent of an ID card. + A certificate specifies the name of an individual, company, or other entity + and certifies that a public key, which is included in the certificate, + belongs to that entity. When you digitally sign a message or other data, the + digital signature for that message is created with the aid of the private key + that corresponds to the public key in your certificate. A certificate is + issued and digitally signed by a certificate + authority (CA). A certificate's validity can be verified by checking + the CA's digital signature. Also called + digital ID, digital passport, public-key certificate, X.509 certificate, and + security certificate. See also public-key + cryptography.

+ +

certificate authority (CA)

A service + that issues a certificate after verifying the identity of the person or + entity the certificate is intended to identify. A CA also renews and revokes + certificates and generates a list of revoked certificates at regular + intervals. CAs can be independent vendors or a person or organization using + certificate-issuing server software (such as &brandShortName; Certificate + Management System). See also certificate, + CRL (certificate revocation list).

+ +

certificate backup password

A + password that protects a certificate that you are backing up or have + previously backed up. Certificate Manager asks you to set this password when + you back up a certificate, and requests it when you attempt to restore a + certificate that has previously been backed up.

+ +

certificate-based + authentication

Verification of identity based on certificates and + public-key cryptography. See also + password-based + authentication.

+ +

certificate chain

A hierarchical series of + certificates signed by successive certificate authorities. A CA certificate + identifies a certificate authority (CA) + and is used to sign certificates issued by that authority. A CA certificate + can in turn be signed by the CA certificate of a parent CA and so on up to a + root CA.

+ +

certificate fingerprint

+ A unique number associated with a certificate. The number is not part of + the certificate itself but is produced by applying a mathematical function to + the contents of the certificate. If the contents of the certificate change, + even by a single character, the function produces a different number. + Certificate fingerprints can therefore be used to verify that certificates + have not been tampered with.

+ +

Certificate + Manager

The part of the browser that allows you to view and manage + certificates. To view the main Certificate Manager window: Open the + &brandShortName; Edit + menu, choose Preferences, click Privacy and Security, and then click Manage + Certificates.

+ +

certificate renewal

The process of + renewing a certificate that is about to + expire.

+ +

certificate verification

When + Certificate Manager verifies a + certificate, it confirms that the digital signature was created by a CA whose + own CA certificate is both on file with Certificate Manager and marked as + trusted for issuing that kind of certificate. It also confirms that the + certificate being verified has not itself been marked as untrusted. Finally, + if the OCSP (Online Certificate Status Protocol) has been + activated, Certificate Manager also performs an online check. It does so by + looking up the certificate in a list of valid certificates maintained at a + URL that is specified either in the certificate itself or + in the browser's Validation preferences. If any of these checks fail, + Certificate Manager marks the certificate as unverified and won't + recognize the identity it certifies.

+ +

cipher

See + cryptographic algorithm.

+ +

client

Software (such as browser software) that sends + requests to and receives information from a server, + which is usually running on a different computer. A computer on which client + software runs is also described as a client.

+ +

client authentication

The process of + identifying a client to a server, + for example with a name and password or with a + client SSL certificate and some + digitally signed data. See also SSL (Secure + Sockets Layer), server + authentication.

+ +

client SSL certificate

A certificate + that a client (such as browser software) presents to a + server to authenticate the identity of the client + (or the identity of the person using the client) using the + SSL (Secure Sockets Layer) protocol. See + also client authentication.

+ +

Component Bar

The toolbar located at the bottom + left of any &brandShortName; window. The Component Bar allows you to switch + between &brandShortName; components by clicking icons for Browser, + Mail & Newsgroups, Composer, and so on.

+ +

A small bit of information stored on your + computer by some websites. When you visit such a + website, the website asks your browser to place one or more cookies on your + hard disk. Later, when you return to the website, your browser sends the + website the cookies that belong to it. Cookies help websites keep track of + information about you, such as the contents of your shopping cart. You can set + your cookie preferences to control how cookies are used and how much + information you are willing to let websites store on them. See also + foreign cookie.

+ +

Cookie Manager

The part of the browser + that you can use to control cookies.

+ +

CRL (certificate revocation list)

A list of revoked + certificates that is generated and signed by a + certificate authority (CA). You can + download the latest CRL to your browser or to a server, then check against it + to make sure that certificates are still valid before permitting their use + for authentication.

+ +

cryptographic algorithm

A set of + rules or directions used to perform cryptographic operations such as + encryption and + decryption. Sometimes called a + cipher.

+ +

cryptography

The art and practice of scrambling + (encrypting) and unscrambling (decrypting) information. For example, + cryptographic techniques are used to scramble an unscramble information + flowing between commercial websites and your browser. See also + public-key cryptography.

+ +

decryption

The process of unscrambling data that + has been encrypted. See also encryption.

+ +

digital ID

+ See certificate.

+ +

digital signature

A code created from both + the data to be signed and the private key of the signer. This code is unique + for each new piece of data. Even a single comma added to a message changes + the digital signature for that message. Successful validation of your digital + signature by appropriate software not only provides evidence that you + approved the transaction or message, but also provides evidence that the data + has not changed since you digitally signed it. A digital signature has + nothing to do with a handwritten signature, although it can sometimes be used + for similar legal purposes. See also + nonrepudiation, + tamper detection.

+ +

distinguished name (DN)

A specially + formatted name that uniquely identifies the subject of a + certificate.

+ +

dual key pairs

Two public-private key + pairs—four keys altogether—corresponding to two separate + certificates. The private key of one pair is used for signing operations, and + the public and private keys of the other pair are used for encryption and + decryption operations. Each pair corresponds to a separate + certificate. See also + public-key cryptography.

+ +

eavesdropping

Surreptitious interception of + information sent over a network by an entity for which the information is not + intended.

+ +

encryption

The process of scrambling information in + a way that disguises its meaning. For example, encrypted connections between + computers make it very difficult for third-parties to unscramble, or + decrypt, information flowing over the connection. Encrypted + information can be decrypted only by someone who possesses the appropriate + key. See also public-key + cryptography.

+ +

encryption certificate

A + certificate whose public key is used for + encryption only. Encryption certificates are not used for signing operations. + See also dual key pairs, + signing certificate.

+ +

encryption key

A private key used for + encryption only. An encryption key and its equivalent private key, plus a + signing key and its equivalent public key, + constitute a dual key pairs.

+ +

extension

A type of add-on + that changes the behavior of &brandShortName; or adds new features to + it.

+ +

feed

A frequently updated source of references to web + pages, usually blog articles or news. Technically it is an XML document + available through a public well-known URL, comprising of several items inside, + each one containing some metadata (possibly including a summary) and an URL + to the full blog or news article. The XML document is regenerated at fixed + intervals, or whenever a new article is published to the website. Web + applications can subscribe to the URL serving the feed and present the new + articles as they are updated in the underlying XML document. There are + specific XML formats for feeds, most common of which are + RSS and Atom.

+ +

fingerprint

See + certificate fingerprint.

+ +

FIPS PUBS 140-1

Federal Information Processing + Standards Publications (FIPS PUBS) 140-1 is a US government standard for + implementations of cryptographic modules—that is, hardware or software + that encrypts and decrypts data or performs other cryptographic operations + (such as creating or verifying digital signatures). Many products sold to the + US government must comply with one or more of the FIPS standards.

+ +

foreign cookie

A cookie + from one website that gets stored on your computer when you visit a different + website. Sometimes a website displays content that is + hosted on another website. That content can be anything from an image to text + or an advertisement. The second website that hosts such elements also has the + ability to store a cookie in your browser, even though you don't visit + it directly. Also known as third-party cookie.

+ +

frame

Frames are web pages + contained inside of an all-encompasssing meta page.

+ +

helper application

Any application that is + used to open or view a file downloaded by the browser. A + plugin is a special kind of helper application that + installs itself into the Plugins directory of the main browser installation + directory and can typically be opened within the browser itself (internally). + Microsoft Word, Adobe Photoshop, and other external applications are + considered helper applications but not plugins, since they don't + install themselves into the browser directory, but can be opened from the + download dialog box.

+ +

home page

The page your browser is set to display + every time you launch it or when you click the Home button. Also used to + refer to the main page for a website, from which you can explore the rest of + the website.

The secure + version of the HTTP protocol that uses SSL to ensure the + privacy of customer data (such as credit card information) while en route + over the Internet.

+ +

IMAP (Internet Message Access Protocol)

A standard mail + server protocol that allows you to store all your messages and any changes to + them on the server rather than on your computer's hard disk. Using IMAP + rather than POP saves disk space and allows you to access + your entire mailbox, including sent mail, drafts, and custom folders, from + any location. Using an IMAP server over a modem is generally faster than + using a POP mail server, since you initially download message headers only. + Not all ISPs support IMAP.

+ +

implicit consent

Also known as implied or + opt-out consent. Used to describe privacy settings that may allow + websites to gather information about you (for example by means of + cookies and online forms) unless you explicitly choose + to withhold your consent by selecting an option on a page that the website + provides for that purpose. Your consent may not be requested when the + information is actually gathered.

+ +

Internet

A worldwide network of millions of computers + that communicate with each other using standard protocols such as + TCP/IP. Originally developed for the US military in + 1969, the Internet grew to include educational and research institutions and, + in the late 1990s, millions of businesses, organizations, and individuals. + Today the Internet is used for email, browsing the + World Wide Web (WWW), instant messaging, + usegroups, and many other purposes.

+ +

IP address (Internet protocol address)

The address + of a computer on a TCP/IP network. Every computer on + the Internet has an IP address. + Clients have either a permanent IP address or one that + is dynamically assigned to them each time they connect with the network. IP + addresses are written as four sets of numbers, like this: 204.171.64.2.

+ +

IRC (Internet Relay Chat)

A protocol used to chat with + other people in real-time using an IRC client.

+ +

ISP (Internet Service Provider)

A company/institution + that provides Internet connections.

Your browser can + automatically download and run Java programs (also called applets).

+ +

JavaScript

A scripting language commonly used to + construct web pages. Programmers use JavaScript to + make web pages more interactive; for example, to display forms and buttons. + JavaScript can be used with Java, but is technically a + separate language. Java is not required for JavaScript to work + correctly.

+ +

key

A large number used by a + cryptographic algorithm to encrypt or + decrypt data. A person's public key, for example, allows other people to + encrypt messages to that person. The encrypted messages must be decrypted + with the corresponding private key. See also + public-key cryptography.

+ +

master password

A password used by + Certificate Manager to protect the master key and/or private keys stored on a + security device. Certificate Manager needs to + access your private keys, for example, when you sign email messages or use + one of your own certificates to identify yourself to a website. It needs to + access your master key when Password Manager or Form Manager reads or adds to + your personal information. You can set or change your master password from + the Master Passwords preferences panel. Each security device requires a + separate master password. See also private key, + master key.

+ +

misrepresentation

Presentation of an entity + as a person or organization that it is not. For example, a website might + pretend to be a furniture store when it is really just a website that takes + credit card payments but never sends any goods. See also + spoofing.

+ +

Navigation Toolbar

The toolbar near the top + of the browser window that includes the Back and Forward buttons.

+ +

nonrepudiation

The inability, of the sender of + a message, to deny having sent the message. A regular hand-written signature + provides one form of nonrepudiation. A + digital signature provides another.

+ +

notification bar

A bar that appears at the + top of the content area to inform you about something that needs your + attention, e.g. when the Password Manager can save a password for you, a + popup has been blocked or an additional plugin is required.

+ +

object signing

+ +

PKCS #11

The public-key cryptography standard that + governs security devices such as smart cards. See also + security device, smart + card.

+ +

PKCS #11 module

A program on your computer + that manages cryptographic services such as encryption and decryption using + the PKCS #11 standard. Also called cryptographic modules, + cryptographic service providers, or security modules, + PKCS #11 modules control either hardware or software devices. A PKCS #11 + module always controls one or more slots, which may be implemented as some + form of physical reader (for example, for reading smart cards) or in + software. Each slot for a PKCS #11 module can in turn contain a + security device (also called token), + which is the hardware or software device that provides cryptographic services + and stores certificates and keys. Certificate + Manager provides two built-in PKCS #11 modules. You may install + additional modules on your computer to control smart card readers or other + hardware devices.

+ +

The standards and services + that facilitate the use of public-key cryptography and certificates in a + networked environment.

+ +

plugin

A type of + helper application that adds new + capabilities to your browser, such as the ability to play audio or video + clips. Unlike other kinds of helper applications, a plugin application + installs itself into the Plugins directory within the main browser + installation directory and typically can be opened within the browser itself + (internally). For example, an audio plugin lets you listen to audio files on + a web page or in an email message. Macromedia Flash + Player and Java are both examples of plugin applications.

+ +

POP (Post Office Protocol)

A standard mail server protocol + that requires you to download new messages to your local + computer—although you can choose to leave copies on the server. With + POP, you can store all your messages, including sent mail, drafts, and custom + folders, on one computer only. By contrast, + IMAP allows you to permanently store all your messages + and any changes to them on the server, where you can access them from any + computer. Most ISPs currently support POP.

+ +

private key

One of a pair of + keys used in public-key cryptography. The private key is + kept secret and is used to decrypt data that has been encrypted with the + corresponding public key.

+ +

proxy

An intermediary or go-between program that + acts as both a server and a + client for the purpose of making requests on behalf of + other clients.

+ +

public key

+ One of a pair of keys used in public-key cryptography. + The public key is distributed freely and published as part of a + certificate. It is typically used to encrypt data + sent to the public key's owner, who then decrypts the data with the + corresponding private key.

+ +

public-key cryptography

A set of + well-established techniques and standards that allow an entity (such as a + person, an organization, or hardware such as a router) to verify its identity + electronically or to sign and encrypt electronic data. Two keys are involved: + a public key and a private + key. The public key is published as part of a + certificate, which associates that key with a + particular identity. The corresponding private key is kept secret. Data + encrypted with the public key can be decrypted only with the private key. +

+ +

root CA

The + certificate authority (CA) with a + self-signed certificate at the top of a + certificate chain. See also + subordinate CA.

+ +

RSS (Really Simple Syndication)

An XML + data format for web feeds.

+ +

search engine

A web-based program that allows + users to search for and retrieve specific information from the + World Wide Web (WWW). The search engine may + search the full text of web documents or a list of keywords, or use + librarians who review web documents and index them manually for retrieval. + Typically, the user types a word or phrase, also called a query, into a + search box, and the search engine displays links to relevant web pages.

+ +

secure authentication

A type of + authentication which uses a + secure connection so the communication + between client and server is encrypted.

+ +

secure connection

A connection between a + client and a server which uses some type of encryption (usually, + SSL) to ensure it can't be intercepted by + third-parties. Most of the time, the server is the one providing the + certificate to identify itself.

+ +

security certificate

See + certificate.

+ +

security device

Hardware or software that + provides cryptographic services such as encryption and decryption and can + store certificates and keys. A smart card is one + example of a security device implemented in hardware. + Certificate Manager contains its own + built-in security device, called the + software security device, that is + always available while the browser is running. Each security device is + protected by its own master password.

+ +

security module

See + PKCS #11 module.

+ +

security token

See + security device.

+ +

server

Software (such as software that serves up web + pages) that receives requests from and sends information to a + client, which is usually running on a different + computer. A computer on which server software runs is also described as a + server.

+ +

server authentication

The process of + identifying a server to a client + by using a server SSL certificate. See + also client authentication, + SSL (Secure Sockets Layer).

+ +

server SSL certificate

A + certificate that a server presents to a + client to authenticate the server's identity using + the SSL (Secure Sockets Layer) protocol.

+ +

signing certificate

A certificate whose + corresponding private key is used to sign + transmitted data, so that the receiver can verify the identity of the sender. + Certificate authorities (CAs) often issue a signing certificate that will be + used to sign email messages at the same time as an + encryption certificate that will be + used to encrypt email messages. See also dual key + pairs, digital signature.

+ +

signing key

A private key used for signing only. + A signing key and its equivalent public key, together with an + encryption key and its equivalent private key, + constitute dual key pairs.

+ +

slot

A piece of hardware, or its equivalent in software, + that is controlled by a PKCS #11 module and + designed to contain a security device.

+ +

smart card

A small device, typically about the size + of a credit card, that contains a microprocessor and is capable of storing + cryptographic information (such as keys and certificates) and performing + cryptographic operations. Smart cards use the PKCS #11 + standard. A smart card is one kind of security + device.

+ +

SMTP (Simple Mail Transfer Protocol)

A protocol that + sends email messages across the Internet.

+ +

SOCKS

A protocol that a proxy + server can use to accept requests from client users in an internal network + so that it can forward them across the Internet.

+ +

software security device

The default + security device used by + Certificate Manager to store private keys + associated with your certificates. In addition to private keys, the software + security device stores the master key used by + Password Manager to encrypt email passwords, + website passwords, and other sensitive information. See also + private key and master + key.

+ +

spoofing

Pretending to be someone else. For example, + a person can pretend to have the email address jdoe@mozilla.com, or + a computer can identify itself as a website called www.mozilla.com + when it is not. Spoofing is one form of + misrepresentation.

+ +

SSL (Secure Sockets Layer)

A protocol that allows mutual + authentication between a client and a + server for the purpose of establishing an authenticated + and encrypted connection. SSL runs above TCP/IP and + below HTTP, LDAP, + IMAP, NNTP, and other high-level network protocols. + The new Internet Engineering Task Force (IETF) standard called Transport + Layer Security (TLS) is based on SSL. See also + authentication, + encryption.

+ +

STARTTLS

An extension to common standard TCP + protocols (like SMTP, POP or IMAP) so the client can tell the server to + use TLS on the same TCP port as for non-secure + connections.

+ +

+ +

A small box with text that appears when + you hover your mouse's cursor over certain items. It usually contains + information regarding the item being hovered over.

+ +

trust

Confident reliance on a person or other entity. In + the context of PKI (public-key infrastructure), trust + usually refers to the relationship between the user of a certificate and the + certificate authority (CA) that issued + the certificate. If you use Certificate Manager to specify that you trust a + CA, Certificate Manager trusts valid certificates issued by that CA unless + you specify otherwise in the settings for individual certificates. You use + the Authorities tab in Certificate Manager to specify the kinds of + certificates you do or don't trust specific CAs to issue.

+ +

URL (Uniform Resource Locator)

The standardized address + that tells your browser how to locate a file or other resource on the Web. + For example: http://www.mozilla.org.
