Tested with badssl.com:
1. Get client certificates from https://badssl.com/download/
2. Convert public portion with `openssl x509 -in badssl.com-client.pem -out CIRCUITPY/cert.pem`
3. Convert private portion with `openssl rsa -in badssl.com-client.pem -out CIRCUITPY/privkey.pem` and the password `badssl.com`
4. Put wifi settings in CIRCUITPY/.env
5. Run the below Python script:
```py
import os
import wifi
import socketpool
import ssl
import adafruit_requests
TEXT_URL = "https://client.badssl.com/"
wifi.radio.connect(os.getenv('WIFI_SSID'), os.getenv('WIFI_PASSWORD'))
pool = socketpool.SocketPool(wifi.radio)
context = ssl.create_default_context()
requests = adafruit_requests.Session(pool, context)
print(f"Fetching from {TEXT_URL} without certificate (should fail)")
response = requests.get(TEXT_URL)
print(f"{response.status_code=}, should be 400 Bad Request")
input("hit enter to continue\r")
print("Loading client certificate")
context.load_cert_chain("/cert.pem", "privkey.pem")
requests = adafruit_requests.Session(pool, context)
print(f"Fetching from {TEXT_URL} with certificate (should succeed)")
response = requests.get(TEXT_URL)
print(f"{response.status_code=}, should be 200 OK")
```
This module has not been built in years, since the (removed) esp8266 port.
Delete the code, as it is not likely to be useful in its current form.
Closes: #7015
Note: at this time, the ssl module on pico_w never verifies the server
certificate. This means it does not actually provide a higher security
level than regular socket / http protocols.
Correction of the timeout value range needed to set the timeout to 'forever'.
The line 162 checks timeout for a value of 0 while the function definition defaults timeout to -1. In the current version of the code timeout is only checked for a value of 0 or in the 'else if' part for a value of > 0. So, values of <0 will not be taken in to account. That is the reason of my modification.
Correction in function request() doc function signature.
(after speaking with @jepler on Discord).
(@jepler: 'Circuitpython always has floats enabled')
Modification of the doc text of function request().
1) The timout parameter is a keyword-only argument; so Added '*,' in the function signature;
2) for parameter timeout an integer is expected, not a float.
Originally, black_bindings found each contiguous "//|" block and sent
it to black independently. This was slower than it needed to be.
Instead, swap the comment prefix: when running black, take off
"//|" prefixes and put "##|" prefixes on all un-prefixed lines.
Then, after black is run, do the opposite operation
This more than doubles the overall speed of "pre-commit run --all",
from 3m20s to 55s CPU time on my local machine (32.5s to under 10s
"elapsed" time)
It also causes a small amount of churn in the bindings, because
black now sees enough context to know whether one 'def' follows another
or ends the 'def's in a 'class'. In the latter case, it adds an extra
newline, which becomes a "//|" line.
I'm less sure why a trailing comma was omitted before down in
rp2pio/StateMachine.c but let's roll with it.
My pings go out, and then they come back
```py
import os
import wifi
import ipaddress
wifi.radio.connect(os.getenv('WIFI_SSID'), os.getenv('WIFI_PASSWORD'))
ipv4 = ipaddress.ip_address("8.8.4.4")
print("Ping google.com: %f ms" % (wifi.radio.ping(ipv4)*1000))
```
