MongoDB project, please report it according to the instructions here.

Installation
PyMongoCrypt can be installed with pip:
$ python -m pip install pymongocrypt
$ python -c "import pymongocrypt; print(pymongocrypt.libmongocrypt_version())"
1.9.0
PyMongoCrypt ships wheels for macOS, Windows, and manylinux2010 that include
an embedded libmongocrypt build.
Installing from wheels on Linux requires pip 19 or later because it adds
support for manylinux2010 wheels.
Older versions of pip will attempt installation using the
pymongocrypt-X.Y.tar.gz source distribution which requires the extra step of
downloading and installing libmongocrypt as described below.
Users can upgrade to pip 19 by running:
$ python -m pip install --upgrade 'pip>=19'

Installing from source
Installing from source (or the pymongocrypt-X.Y.tar.gz source distribution,
or pip < 19 on Linux) requires an extra step of installing libmongocrypt.
First, install PyMongoCrypt from source:
$ git clone git@github.com:mongodb/libmongocrypt.git
$ python -m pip install ./libmongocrypt/bindings/python
Next, install libmongocrypt:

Installing libmongocrypt
libmongocrypt is continuously built and published on evergreen.
The latest tarball containing libmongocrypt built on all supported variants is
published here.
Download and extract libmongocrypt-all.tar.gz and set
PYMONGOCRYPT_LIB to the path to your operating system’s libmongocrypt.so file.
For example:
$ curl -O https://s3.amazonaws.com/mciuploads/libmongocrypt/all/master/latest/libmongocrypt-all.tar.gz
$ mkdir libmongocrypt-all && tar xzf libmongocrypt-all.tar.gz -C libmongocrypt-all
$ ls libmongocrypt-all

macOS:
$ # Set PYMONGOCRYPT_LIB for macOS:
$ export PYMONGOCRYPT_LIB=$(pwd)/libmongocrypt-all/macos/lib/libmongocrypt.dylib
$ python -c "import pymongocrypt; print(pymongocrypt.libmongocrypt_version())"
1.9.0
Windows:
$ # Set PYMONGOCRYPT_LIB for Windows:
$ chmod +x $(pwd)/libmongocrypt-all/windows-test/bin/mongocrypt.dll
$ export PYMONGOCRYPT_LIB=$(pwd)/libmongocrypt-all/windows-test/bin/mongocrypt.dll
$ python -c "import pymongocrypt; print(pymongocrypt.libmongocrypt_version())"
1.9.0
Linux: set the libmongocrypt build for your platform, for example for Ubuntu 22.04 x86_64:
$ # Set PYMONGOCRYPT_LIB for Ubuntu 22.04 x86_64:
$ export PYMONGOCRYPT_LIB=$(pwd)/libmongocrypt-all/ubuntu2204-64/lib/libmongocrypt.so
$ python -c "import pymongocrypt; print(pymongocrypt.libmongocrypt_version())"
1.9.0
$ # Check that native crypto is enabled for better performance:
$ python -c 'from pymongocrypt.binding import lib;print(lib.mongocrypt_is_crypto_available())'
True
Note if your Linux platform is not available, the generic RHEL 6.2 x86_64 “nocrypto” build
should still be compatible however the “nocrypto” build will result in lower performance
for encryption and decryption:
$ # Set PYMONGOCRYPT_LIB for RHEL 6.2 x86_64:
$ export PYMONGOCRYPT_LIB=$(pwd)/libmongocrypt-all/rhel-62-64-bit/nocrypto/lib64/libmongocrypt.so
$ python -c "import pymongocrypt; print(pymongocrypt.libmongocrypt_version())"
1.9.0
$ python -c 'from pymongocrypt.binding import lib;print(lib.mongocrypt_is_crypto_available())'
False
Other methods of installation (brew, rpm, yum, apt-get, deb, etc…) are documented here:

Dependencies
PyMongoCrypt supports Python 3.8+ and PyPy3.9+.
PyMongoCrypt requires cffi and
cryptography.
If not installed using one of the official wheels, PyMongoCrypt also requires
libmongocrypt to be installed on your system. If libmongocrypt is not
installed you will see an error like this:
>>> import pymongocrypt
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pymongocrypt/__init__.py", line 15, in <module>
from pymongocrypt.binding import libmongocrypt_version, lib
File "pymongocrypt/binding.py", line 803, in <module>
lib = ffi.dlopen(os.environ.get('PYMONGOCRYPT_LIB', 'mongocrypt'))
File "/.../lib/python3.8/site-packages/cffi/api.py", line 146, in dlopen

raise OSError(msg)
OSError: ctypes.util.find_library() did not manage to locate a library called 'mongocrypt'
Use the PYMONGOCRYPT_LIB environment variable to load a locally installed
libmongocrypt build without relying on platform specific library path environment
variables, like LD_LIBRARY_PATH. For example:
$ export PYMONGOCRYPT_LIB='/path/to/libmongocrypt.so'
$ python -c "import pymongocrypt; print(pymongocrypt.libmongocrypt_version())"
1.9.0

Testing
The easiest way to run the tests is to run python setup.py test in
the root of the distribution.
