## Requirements
## Installing
Volatility 3 requires Python 3.8.0 or later. To install the most minimal set of dependencies (some plugins will not work) use a command such as:
Volatility 3 requires Python 3.8.0 or later and is published on the [PyPi registry](https://pypi.org/project/volatility3).
```shell
pip3 install -r requirements-minimal.txt
pip install volatility3
```
Alternately, the minimal packages will be installed automatically when Volatility 3 is installed using pip. However, as noted in the Quick Start section below, Volatility 3 does not *need* to be installed prior to using it.
If you want to use the latest development version of Volatility 3 we recommend you manually clone this repository and install an editable version of the project.
We recommend you use a virtual environment to keep installed dependencies separate from system packages.
```shell
pip3 install .
```
To enable the full range of Volatility 3 functionality, use a command like the one below. For partial functionality, comment out any unnecessary packages in [requirements.txt](requirements.txt) prior to running the command.
```shell
pip3 install -r requirements.txt
```
## Downloading Volatility
The latest stable version of Volatility will always be the stable branch of the GitHub repository. You can get the latest version of the code using the following command:
The latest stable version of Volatility will always be the `stable` branch of the GitHub repository. The default branch is `develop`.
```shell
git clone https://github.com/volatilityfoundation/volatility3.git
cd volatility3/
python3 -m venv venv && . venv/bin/activate
pip install -e .[dev]
```
## Quick Start
1. Clone the latest version of Volatility from GitHub:
```shell
git clone https://github.com/volatilityfoundation/volatility3.git
```
1. Install Volatility 3 as documented in the Installing section of the readme.
2. See available options:
```shell
python3 vol.py -h
vol -h
```
3. To get more information on a Windows memory sample and to make sure
Volatility supports that sample type, run
`python3 vol.py -f <imagepath> windows.info`
Example:
3. To get more information on a Windows memory sample and to make sure Volatility supports that sample type, run `vol -f <imagepath> windows.info`:
```shell
python3 vol.py -f /home/user/samples/stuxnet.vmem windows.info
vol -f /home/user/samples/stuxnet.vmem windows.info
```
4. Run some other plugins. The `-f` or `--single-location` is not strictly
required, but most plugins expect a single sample. Some also
require/accept other options. Run `python3 vol.py <plugin> -h`
for more information on a particular command.

fp.write(data)
As this demonstrates, all of the python is accessible, as are the volshell built in functions (such as `cc` which
creates a constructable, like a layer or a symbol table).
User Convenience
----------------
There are functions available that make often-done tasks easier, and generally provide a shell-like experience. These can be listed using `help()` which, as already mentioned, is advertised when volshell starts.
Loading files
-------------
^^^^^^^^^^^^^
Files can be loaded as physical layers using the `load_file` or `lf` command, which takes a filename or a URI. This will be added
to `context.layers` and can be accessed by the name returned by `lf`.
Regex
^^^^^
It is easy to scan for some bytes or a pattern using `regex_scan` or `rx`.

You can, of course, specify a different layer name as well.

# physical address from a PTE. In Volatility3, this is referred to as _maxphyaddr.
#
# Until kernel version 4.17, Linux x86-64 used a 46-bit mask. With commit
# b83ce5ee91471d19c403ff91227204fb37c95fb2, this was extended to 52 bits,
# applying to both 4 and 5-level page tables.
#
# We initially used 52 bits for all Intel 64-bit systems, but this produced incorrect
# results for PROT_NONE pages. Since the mask value is defined by a preprocessor macro,
# it's difficult to detect the exact bit shift used in the current kernel.
# Using 46 bits has proven reliable for our use case, as seen in tools like crashtool.
