Such keys are placed on a certificate revocation list or CRL. session key - key used for one message or an entire communications session. See traffic encryption key. symmetric key - a key that is used both to encrypt and decrypt a message. Symmetric keys are typically used with a cipher and must be kept secret to maintain confidentiality.

This is a list of telecommunications encryption terms. This list is derived in part from the Glossary of Telecommunication Terms published as Federal Standard 1037C . A5/1 – a stream cipher used to provide over-the-air communication privacy in the GSM cellular telephone standard.
In formal mathematical terms, a "cryptosystem" is the ordered list of elements of finite possible plaintexts, finite possible cyphertexts, finite possible keys, and the encryption and decryption algorithms that correspond to each key. Keys are important both formally and in actual practice, as ciphers without variable keys can be trivially ...
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...

A simple illustration of public-key cryptography, one of the most widely used forms of encryption. In cryptography, encryption (more specifically, encoding) is the process of transforming information in a way that, ideally, only authorized parties can decode.
