ent

NAME
ent - pseudo random number sequence test

SYNOPSIS
ent [ -b -c -f -t -u ] [ infile ]

DESCRIPTION
Preforms Entropy, Chi-square, Arithmetic Mean, Monte-Carlo-Pi and Serial Correlation tests.

OPTIONS
-b
    The input is treated as a stream of bits rather than bytes. -c
    Print a table of the number of occurrences of each possible byte (or bit, if the -b option is also specified) value, and the fraction of the overall file made up by that value. Printable characters in the ISO 8859-1 Latin-1 character set are shown along with their decimal byte values. -f
    Fold upper case letters to lower case before conducting tests. Folding is done based on the ISO 8859-1 Latin-1 character set. -t
    Terse mode output is written in Comma Separated Value (CSV) format. -u
    Print basic usage information.

FILES
If no infile is specified, ent reads from stdin. Output is always written to stdout. ent processes one infile at a time.

  TERSE MODE OUTPUT FORMAT
In Terse mode, row 0 is a header row which identifies the content of row 1. If the -c option is specified, rows 2 and 3, which contain character count information, are appended. If the -b option is specified, only two type 3 rows are shown for bits 0 and 1. Otherwise, 256 type 3 rows are shown, one for each possible byte.
