jEnt - A Java console application that applies
statistical tests to a sequence of bytes to assist in the testing and
evaluation of pseudo-random sequence generators.
- Synopsis
- jEnt [ -bctuv ] [ input_file ]
- Description
-
jEnt performs a series of statistical tests on the stream of bytes contained
in input_file or from the standard input stream if input_file
is not specified. Output is produced on the standard output stream.
Input bytes are assumed to be in binary format. If no input is available at the
time jEnt is ready to read the input stream jEnt does not wait for input, but
exits with a warning message.
- Available options are:
- -b Treat input as a stream of bits
- -c Print byte (or bit) occurrence counts
- -t Print output in Comma Separated Value (CSV) format
- -u Print usage information
- -v Print copyright and current version information
-
A more complete description of
the series of tests performed, available options
(except that the fold option is not supported by jEnt), 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. There are other small differences.
