SSL import error

[bludin]

The import statement on line 15 of server.py causes an error on platforms that do not support SSL (eg M4)

What network are you wanting to use on the M4?

ssl is built in on devices with native wifi, and also on devices with built-in (WIZnet) Ethernet. There isn't necessarily room to put it on every device, but you can do a custom build (may need to delete other things to make room).

For ESP32SPI, see this thread:
#86 (comment)
and this PR:
adafruit/Adafruit_CircuitPython_ESP32SPI#218

I just entered this on behalf of somebody I helped in the Adafruit Circuitpython forum. I proposed a little change to the code there, that would allow for the import and use on non-SSL-enabled platforms.

Currently, importing the hashlib module works in a similar way.

try:
    try:
        import hashlib
    except ImportError:
        import adafruit_hashlib as hashlib
except ImportError:
    print(
        "WARNING: hashlib module not available and adafruit_hashlib not installed.",
        "Websocket support will not work.",
    )

Maybe this could be applied for ssl too? If there is a use case for adafruit_httpserver on boards that do not have ssl module, in my opinion it should not throw an error just because it is missing a module it wouldn't use either way.
