It's generally a bad idea to keep [card specific] key material lying around unencrypted in CSV files. The industry standard solution in the GSMA is a so-called "transport key", which encrypts the key material. Let's introduce support for this in the CardKeyProvider (and specifically, the CardKeyProviderCSV) and allow the user to specify transport key material as command line options to pySim-shell. Different transport keys can be used for different key materials, so allow specification of keys on a CSV-column base. The higher-level goal is to allow the CSV file not only to store the ADM keys (like now), but also global platform key material for establishing SCP towards various security domains in a given card.

pySim - Read, Write and Browse Programmable SIM/USIM/ISIM/HPSIM Cards
This repository contains a number of Python programs that can be used to read, program (write) and browse all fields/parameters/files on SIM/USIM/ISIM/HPSIM cards used in 3GPP cellular networks from 2G to 5G.
Note that the access control configuration of normal production cards issue by operators will restrict significantly which files a normal user can read, and particularly write to.
The full functionality of pySim hence can only be used with on so-called programmable SIM/USIM/ISIM/HPSIM cards.
Such SIM/USIM/ISIM/HPSIM cards are special cards, which - unlike those issued by regular commercial operators - come with the kind of keys that allow you to write the files/fields that normally only an operator can program.
This is useful particularly if you are running your own cellular network, and want to configure your own SIM/USIM/ISIM/HPSIM cards for that network.

Documentation
The pySim user manual can be built from this very source code by means of sphinx (with sphinxcontrib-napoleon and sphinx-argparse). See the Makefile in the 'docs' directory.
A pre-rendered HTML user manual of the current pySim 'git master' is available from https://downloads.osmocom.org/docs/latest/pysim/ and a downloadable PDF version is published at https://downloads.osmocom.org/docs/latest/osmopysim-usermanual.pdf.
A slightly dated video presentation about pySim-shell can be found at https://media.ccc.de/v/osmodevcall-20210409-laforge-pysim-shell.
pySim-shell vs. legacy tools
While you will find a lot of online resources still describing the use of pySim-prog.py and pySim-read.py, those tools are considered legacy by now and have by far been superseded by the much more capable pySim-shell. We strongly encourage users to adopt pySim-shell, unless they have very specific requirements like batch programming of large quantities of cards, which is about the only remaining use case for the legacy tools.
Git Repository

Installation
Please install the following dependencies:
- bidict
- cmd2 >= 1.5.0
- colorlog
- construct >= 2.9.51
- gsm0338
- jsonpath-ng
- packaging
- pycryptodomex
- pyscard
- pyserial

Example for Debian:
sudo apt-get install --no-install-recommends \
pcscd libpcsclite-dev \
python3 \
python3-setuptools \
python3-pycryptodome \
python3-pyscard \

After installing all dependencies, the pySim applications pySim-read.py, pySim-prog.py and pySim-shell.py may be started directly from the cloned repository.
In addition to the dependencies above pySim-trace.py requires tshark and the python package pyshark to be installed. It is known that the tshark package
in Debian versions before 11 may not work with pyshark.
Archlinux Package
Archlinux users may install the package python-pysim-git
yay.
# Install
yay -Sy python-pysim-git
# Uninstall
sudo pacman -Rs python-pysim-git
