- .TH ENT 1
- .SH NAME
- ent - pseudo random number sequence test
- .SH SYNOPSIS
- ent [ -b -c -f -t -u ] [ infile ]
- .SH DESCRIPTION
- Preforms Entropy, Chi-square, Arithmetic Mean, Monte-Carlo-Pi and Serial Correlation tests.
- .SH OPTIONS
- .B -b
- The input is treated as a stream of bits rather than bytes.
- .B -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.
- .B -f
- Fold upper case letters to lower case before conducting tests. Folding is done based on the ISO 8859-1 Latin-1 character set.
- .B -t
- Terse mode output is written in Comma Separated Value (CSV) format.
- .B -u
- Print basic usage information.
- .SH FILES
- If no infile is specified, ent reads from stdin. Output is always written to stdout. ent processes one infile at a time.
- .SS 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.
