(a)  

Software intended to damage a computing system or to take partial control over its operation.

(a)  

The use of a program to record every keystroke made by a computer user in order to gain fraudulent access to passwords and other confidential information.

(a)  

A wireless access point that gives unauthorized access to secure networks.

(a)  

The science and art of delivering a message securely and confidentially.

(a)  

The process of encoding data to prevent unauthorized access, such as converting plaintext to ciphertext.

(a)  

The process of decoding the date, the reverse of encryption process, making the data human-readable again.

(a)  

A cipher in which each letter in an alphabet is replaced with a different character or symbol.

(a)  

A string of characters used as a parameter that determines the output of an encryption algorithm.

(a)  

A method for determining a solution to a problem by sequentially testing all possible solutions.

(a)  

An encryption method where the sender and receiver share a private key (such as a number, word, or phrase) to use in the encryption algorithm.

(a)  

Also called shared key encryption, a process in which a single key is used in both the encryption and decryption algorithm to encode/decode data.

(a)  

A method of paired key encryption in which the key used to encrypt data is made available to anybody, and its corresponding decryption key is kept secret.

(a)  

Two keys that are related in such a way that one can be used to encrypt data, which can then only be decrypted by the other key.

(a)  

Also called public-key encryption, an encryption method that uses two keys, a public key and a private key, belonging to one owner.

(a)  

An asymmetric public key encryption algorithm developed by Rivest, Shamir, and Adleman, an American computer and network security company.

(a)  

A digital document used to verify the authenticity of a server or public key.

(a)  

Confirm your identity using knowledge known only to you.

(a)

(a)  

A way programmers share their code with other programmers.

(a)  

A standard component of a graphical user interface (GUI).

(a)  

An input value to a command that specifies the values of the parameters when a procedure is called.

(a)  

A mistake in the algorithm or program that causes it to behave incorrectly, unexpectedly, or with undesirable results. The code compiles and runs, but causes problems elsewhere, for example, giving incorrect information or mismanaging data.

(a)  

Precise rules defining how the letters, words, and punctuation of a programming language are required to be used together.

(a)  

An expression that evaluates to either true or false; used in the conditional of an "if" structure.

(a)  

A mistake in the program that occurs during the execution of a program.

(a)  

A literal value (such as 5 or "hello") that is hard coded into a program instead of being assigned to a well-named variable.

(a)  

A designated stopping place in your code. Using a debugger, it lets you examine the state of the program and its variables.

(a)  

An error or other message raised by the interpreter or compiler to indicate a special circumstance.
