In the help for pip -install I noticed the install option --platform -> "Only use wheels compatible with platform. Defaults to the platform of the running system."

I was thinking I could use this option to get the Linux binaries on my windows machine however I cannot seem to get it to work as expected.

What is the proper syntax for this option, and what exactly is a "Wheel"?

pip install --platform ubuntu --only-binary=:all: cryptography

Returns Errors:

ERROR: Could not find a version that satisfies the requirement cryptography (from versions: none)
ERROR: No matching distribution found for cryptography

Edit: Thanks for the initial responses. When trying to install the linux .so files on a windows machine I am getting the same errors when using various versions of the command 

pip install --platform linux_x86_64 --only-binary=:all: cryptography

In the cryptography document it identifies various linux supported distributions. https://cryptography.io/en/latest/installation/

Does anyone know how to get cryptography .so files using a windows machine?

A Wheel is a pre-built distribution format that provides faster installation compared to Source Distributions (sdist), especially when a project contains compiled extensions[2].

I don't think ubuntu is a possible value for the --platform option. Try with something like linux_x86_64 or linux_i386
