+<#
+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:

+        To understand the algorithm below, it is necessary to treat the O and U strings in the Encrypt dictionary
+        as made up of three sections. The first 32 bytes are a hash value (explained below). The next 8 bytes are
+        called the Validation Salt. The final 8 bytes are called the Key Salt.
+
+        1. The password string is generated from Unicode input by processing the input string with the SASLprep
+           (IETF RFC 4013) profile of stringprep (IETF RFC 3454), and then converting to a UTF-8 representation.
+        2. Truncate the UTF-8 representation to 127 bytes if it is longer than 127 bytes.
+        3. Test the password against the owner key by computing the SHA-256 hash of the UTF-8 password
+           concatenated with the 8 bytes of owner Validation Salt, concatenated with the 48-byte U string. If the
+           32-byte result matches the first 32 bytes of the O string, this is the owner password.
+           Compute an intermediate owner key by computing the SHA-256 hash of the UTF-8 password
+           concatenated with the 8 bytes of owner Key Salt, concatenated with the 48-byte U string. The 32-byte
+           result is the key used to decrypt the 32-byte OE string using AES-256 in CBC mode with no padding and
+           an initialization vector of zero. The 32-byte result is the file encryption key.
+        4. Test the password against the user key by computing the SHA-256 hash of the UTF-8 password
+           concatenated with the 8 bytes of user Validation Salt. If the 32 byte result matches the first 32 bytes of
+           the U string, this is the user password.
+           Compute an intermediate user key by computing the SHA-256 hash of the UTF-8 password
+           concatenated with the 8 bytes of user Key Salt. The 32-byte result is the key used to decrypt the 32-byte
+           UE string using AES-256 in CBC mode with no padding and an initialization vector of zero. The 32-byte
+           result is the file encryption key.
+        5. Decrypt the 16-byte Perms string using AES-256 in ECB mode with an initialization vector of zero and
+           the file encryption key as the key. Verify that bytes 9-11 of the result are the characters ‘a’, ‘d’, ‘b’. Bytes

+           object containing it.
+        b) For all strings and streams without crypt filter specifier; treating the object number and generation number
+           as binary integers, extend the original n-byte encryption key to n + 5 bytes by appending the low-order 3
+           bytes of the object number and the low-order 2 bytes of the generation number in that order, low-order byte
+           first. (n is 5 unless the value of V in the encryption dictionary is greater than 1, in which case n is the value
+           of Length divided by 8.)
+           If using the AES algorithm, extend the encryption key an additional 4 bytes by adding the value “sAlT”,
+           which corresponds to the hexadecimal values 0x73, 0x41, 0x6C, 0x54. (This addition is done for backward
+           compatibility and is not intended to provide additional security.)
+        c) Initialize the MD5 hash function and pass the result of step (b) as input to this function.
+        d) Use the first (n + 5) bytes, up to a maximum of 16, of the output from the MD5 hash as the key for the RC4
+           or AES symmetric key algorithms, along with the string or stream data to be encrypted.

+Certifi: Python SSL Certificates
+================================
+
+Certifi provides Mozilla's carefully curated collection of Root Certificates for
+validating the trustworthiness of SSL certificates while verifying the identity
+of TLS hosts. It has been extracted from the `Requests`_ project.
+
+Installation
+------------
+
+``certifi`` is available on PyPI. Simply install it with ``pip``::
+
+    $ pip install certifi
+
+Usage
+-----
+
+To reference the installed certificate authority (CA) bundle, you can use the
+built-in function::
+
+    >>> import certifi
+
+    >>> certifi.where()
+    '/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'
+
+Or from the command line::
+
+    $ python -m certifi
+    /usr/local/lib/python3.7/site-packages/certifi/cacert.pem
+
+Enjoy!
+
+.. _`Requests`: https://requests.readthedocs.io/en/master/
+
+Addition/Removal of Certificates
+--------------------------------
+
+Certifi does not support any addition/removal or other modification of the
+CA trust store content. This project is intended to provide a reliable and
+highly portable root of trust to python deployments. Look to upstream projects
+for methods to use alternate trust.
