With the recent (2019-09-01) changes and creation of make install
command it is easy to get lost.
If you install the Proxmark tools with make install
, they will go under the prefix /usr/local/
but if you install the tools from your distro, there are chances the path is /usr
so you'll have to adapt the paths presented here.

The main Proxmark3 executables / shellscripts will be copied to
/usr/local/bin/
- executables:
proxmark3
- scripts:
pm3
,pm3-flash
,pm3-flash-all
,pm3-flash-bootloader
,pm3-flash-fullimage
Some more executable / scripts will be copied to
/usr/local/share/proxmark3/tools
- executables:
mfkey32
,mfkey32v2
,mfkey64
,nonce2key
- scripts:
pm3_eml2lower.sh
,pm3_eml2upper.sh
,pm3_mfdread.py
,pm3_mfd2eml.py
,pm3_eml2mfd.py
,findbits.py
,rfidtest.pl
,xorcheck.py

The recovery / firmware files will be copied to
/usr/local/share/proxmark3/firmware
- Proxmark3 firmware:
bootrom.elf
,fullimage.elf
,proxmark3_recovery.bin
(used for JTAG) - SIM firmware:
sim011.bin
,sim011.sha512.txt
^Top
Proxmark3 client has a lot of sample trace files for many different low frequency tags. They will be copied to
/usr/local/share/proxmark3/traces
^Top
JTAG configurations and helper scripts for OpenOCD will be copied to
/usr/local/share/proxmark3/jtag_openocd
^Top
Dictionaries used by the client will be copied to
/usr/local/share/proxmark3/dictionaries
Here you find the default dictionaries used for commands like hf mf chk
, hf mf fchk
, lf t55xx chk
A dictionary file is a text based file with one key per line in hexadecimal form.
The length of the key is decided by the Proxmark3 client for the different commands. All chars afterwards on line is ignored.
if key isn't a hex number, the key is ignored.
- t55xx, Mifare Ultralight/NTAG - uses 4 hexbytes (11223344)
- Mifare classic uses 6 hexbytes (112233445566)
- iClass uses 8 hexbytes (1122334455667788)
See here how to add your own dictionaries.

Cmd scripts used by the client will be copied to
/usr/local/share/proxmark3/cmdscripts
See here how to add your own cmd scripts.
^Top
Lua libraries and scripts used by the client will be copied to
/usr/local/share/proxmark3/lualibs
/usr/local/share/proxmark3/luascripts
lualibs
contains the supporting lua libraries used for lua scripts. Basically reused functions in a lua file like converting string to hex etc.
See here how to add your own Lua scripts.
^Top
Various resources used by the client will be copied to
/usr/local/share/proxmark3/resources
It comprises the needed files for commands like hardnested, fido, EMV, iClass.
See here how to add your own resources.
^Top
Documentation will be copied to
/usr/local/share/doc/proxmark3
^Top
The client will make use of a personal directory ~/.proxmark3
(or more precisely $HOME/.proxmark3
)
^Top
We have now a rolling log file, created new per day. All these logfiles and the history file are now located at
~/.proxmark3/history.txt
~/.proxmark3/log_YYYYMMDD.txt
^Top
If you wants to add scripts, dictionaries or other resources, you can use the same structure as the installed directory structure and add your own files there, e.g.
~/.proxmark3/cmdscripts/mycmdscript.cmd
~/.proxmark3/dictionaries/mydict.dic
~/.proxmark3/luascripts/myluascript.lua
~/.proxmark3/resources/oids.json
~/.proxmark3/traces/mylftrace.pm3
If you add a file with the same name as the file provided with the Proxmark3 installation, it will take precedence.
See also Scripts on how to write your own scripts.
^Top
With the directory structure explained above, the client applies some heuristics to find its files or the files you specified in command line.
^Top
It adds the expected suffix if you didn't provide it yet, then it looks (by order of precedence):
- in the current directory, or in the path if you provided also a path, so it works with autocompletion
- in the
~/.proxmark3
directory structure as seen above, so it works with your stuffs - in the repo directory structure, so it works as usual if used from the Git repo
- in the installed directory structure, so it works when installed
^Top
The client is using searchFile (in client/fileutils.c) when calling a Proxmark3 command with a filename or when the client needs to find its files. searchFile takes as argument a relative path pm3dir, a file to search and possibly a suffix.
So for example when using searchFile over a filename supposed to be a dictionary file, it's called with pm3dir=dictionaries/ and suffix=.dic. When a user provides a filename (including possibly a path), searchFile will search different locations and return as soon as a file is found:
- Add the suffix if the suffix is not yet present, so: foo -> foo.dic and foo.dic -> foo.dic
- If the filename is an absolute path (/tmp/foo.dic), take it as it is, try to access the file and return.
- If the filename is an explicit relative path (./foo.dic), take it as it is, try to access the file from the current directory and return.
- Try to find the filename as relative path (foo.dic -> ./foo.dic), so filenames provided by CLI autocompletion work as expected.
- Try to find the filename in the pm3dir relative to the user directory $HOME/.proxmark3 (foo.dic -> ~/.proxmark3/dictionaries/foo.dic)
- Try to find the filename in the pm3dir relative to where the client binary is when in the repo configuration (foo.dic -> $(path_to_dir_of_proxmark3_bin)/dictionaries/foo.dic), so when the client is executed from a repo workdir, filenames are searched in the expected location.
- Try to find the filename in the pm3dir relative to where the client binary is when in the installed configuration (foo.dic -> $(path_to_dir_of_proxmark3_bin)/../share/proxmark3/dictionaries/foo.dic which resolves to e.g. /usr/share/proxmark3/dictionaries/foo.dic or /usr/local/share/proxmark3/dictionaries/foo.dic), so when the client is executed from a repo workdir, filenames are searched in the expected location.

You can provide your own lua or cmd scripts. Look at existing scripts for ideas how to create your own scripts.
^Top
For cmd scripts, the command line scripts, the client can run a text file containing Proxmark3 commands.
A samplefile could be like this.
$> cat myscript.cmd
rem running some HF-based info commands
hf 14a info
hf mfu info
rem done
You call it with:
$> pm3 -s myscript.cmd
The client will execute each one of the commands in order and then exit. There is also a possibility to remain in the client afterwards with the -i parameter:
$> pm3 -s myscript.cmd -i
You can place it in ~/.proxmark3/cmdscripts/
and it will be found automatically.
You can skip the script file extension, it works equally well with.
pm3 -s myscript
^Top
You can also use the magic of shebangs to make an executable script, e.g. taking the example above, we can write:
$> cat myscript.cmd
#!/usr/bin/env -S pm3 -s
hf 14a info
hf mfu info
$> chmod +x myscript.cmd
$> ./myscript.cmd
And it will be executed invoking the pm3
script.
Use the following if your script is intended to work offline.
#!/usr/bin/env -S proxmark3 -s
Beware the shebang trick is not available on all the platforms, it requires your env
to accept the -S
switch.
