"""A helper module that injects SecureTransport, on import.
|
|
|
|
The import should be done as early as possible, to ensure all requests and
|
|
sessions (or whatever) are created after injecting SecureTransport.
|
|
|
|
Note that we only do the injection on macOS, when the linked OpenSSL is too
|
|
old to handle TLSv1.2.
