Part of a program that causes an error or undesired output.

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

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

A literal value that is hard coded into a program instead of being assigned to a well-named variable.

A mistake in the algorithm or program that causes it to behave incorrectly, unexpectedly, or with undesirable results.
