MAT2 er ett free open source program skrevet i python3 som tillater deg å fjerne metadata fra audiofiler , bildefiler , torrents og andre filer. De av dere som er kjent med Tails , som bruker GNOME desktop , har kanskje vært borti MAT som hadde en liten graphical user interface. Bruker du GNOME eller nautilus file manager kan du bruke en extension for å få det samme med MAT2.

MAT2 er enkelt å bruke. :

Hvordan du bruker MAT2:

Code: Select all

$mat2 -h
usage: mat2 [-h] [-v] [-l] [--check-dependencies] [-V]
            [--unknown-members policy] [-s | -L]
            [files [files ...]]

Metadata anonymisation toolkit 2

positional arguments:
  files                 the files to process

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit
  -l, --list            list all supported fileformats
  --check-dependencies  check if MAT2 has all the dependencies it needs
  -V, --verbose         show more verbose status information
  --unknown-members policy
                        how to handle unknown members of archive-style files
                        (policy should be one of: abort, omit, keep) [Default:
                        abort]
  -s, --show            list harmful metadata detectable by MAT2 without
                        removing them
  -L, --lightweight     remove SOME metadata
- Lag en tekst fil med en text editor eller bruk noe enda enklere , spiller ingen rolle

Code: Select all

$nano mat2test.txt
- Kommando for å se hva som står i tekstfilen , uvensetlig.

Code: Select all

$cat mat2test.txt
Hei dette er en test!

- Sjekk om tekstfilen inneholder noe metadata

Code: Select all

$mat2 -s mat2test.txt
  No metadata found
- Kommando for å fjerne metadata fra filen (selv om kommando ovenfor viste null)

Code: Select all

$mat2 mat2test.txt

- Da skal du sitte igjen med den orginale tekstfilen og en ny cleaned tekstfil

Code: Select all

$ls 
mat2test.cleaned.txt  mat2test.txt

- Da kan vi slette den orginale filen og beholde den filen som vi har fjernet metadata fra.

Code: Select all

$shred -u mat2test.txt

NAME

mat2 - the metadata anonymisation toolkit 2

SYNOPSIS
mat2 [-h] [-v] [-l] [-V] [-s | -L] [files [files ...]]

DESCRIPTION

mat2 removes metadata from various fileformats. It supports a wide variety of file formats, audio, office, images, …

Careful, mat2 does not clean files in-place, instead, it will produce a file with the word "cleaned" between the filename and its extension, for example "file‐
name.cleaned.png" for a file named "filename.png".

files the files to process


optional arguments:
-h, --help
show this help message and exit

-v, --version
show program's version number and exit

-l, --list
list all supported fileformats

--check-dependencies
check if MAT2 has all the dependencies it needs

-V, --verbose
show more verbose status information

--unknown-members policy
how to handle unknown members of archive-style files (policy should be one of: abort, omit, keep)

-s, --show
list harmful metadata detectable by MAT2 without removing them

-L, --lightweight
remove SOME metadata

EXAMPLES
To remove all the metadata from a PDF file:

mat2 ./myfile.pdf

BUGS
While mat2 does its very best to remove every single metadata, it's still in beta, and some might remain. Should you encounter some issues, check the bugtracker:
