Description

GUIjEnt is a GUI front-end for jEnt, the Java console application that applies statistical tests to a sequence of bytes to assist in the testing and evaluation of pseudo-random sequence generators. GUIjEnt provides a visual point and click interface to specify input and output files and options before calling jEnt.

jEnt performs a series of statistical tests on the stream of bytes contained in an input file. Output from jEnt is displayed in a panel of the GUI window. Optionally, the output can be written to a file. The input file is assumed to be in binary format.

Options are available to:

treat input as a stream of bits.

display byte (or bit) occurrence counts.

display output in Comma Separated Value (CSV) format.

A more complete description of the series of tests performed and the appearance and interpretation of the output can be found by reading a local copy of John Walker's original ent web page.

jEnt is a translation of ent, a program originally written in C by John Walker.

Bugs

The fold option ( -f ) is not supported in jEnt. The HTML browser panel used to display help information provides minimal HTML support. Minimized window icons may appear small under Linux.
