A key generator [1] [2] [3] 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.
Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender encrypts data with the receiver's public key; only the holder of the private key can ...

This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
In batch mode, non-existent environment variables are replaced by a zero-length string. Standard environment variables or reserved environment variables include: %APPEND% (supported since DOS 3.3) This variable contains a semicolon-delimited list of directories in which to search for files.
PHP 7.0 also has type declarations for function return types, expressed by placing the type name after the list of parameters, preceded by a colon. [70] For example, the getAdder function from the earlier example could be annotated with types like so in PHP 7:
