HTTPS for web server in Raspberry Pi - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start a simple HTTPS server using Python's http.server module.

Raspberry Pi

import http.server
import ssl

server_address = ('localhost', 4443)
httpd = http.server.HTTPServer(server_address, http.server.SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket(httpd.socket, keyfile='[1]', certfile='server.pem', server_side=True)
httpd.serve_forever()

Aserver.key

Bserver.pem

Ckey.pem

Dcert.pem

💡 Hint

Common Mistakes

Using the certificate file instead of the key file for the keyfile parameter.

The keyfile parameter requires the private key file, commonly named server.key.

medium

Complete the command to generate a self-signed certificate using OpenSSL.

Raspberry Pi

openssl req -x509 -newkey rsa:4096 -keyout [1] -out server.pem -days 365 -nodes

Drag options to blanks, or click blank then click option'

Aserver.pem

Bkey.pem

Cserver.key

Dcert.pem

💡 Hint

Common Mistakes

Confusing the certificate output file with the key output file.

The -keyout option specifies the filename for the private key, commonly server.key.

hard

Fix the error in the Python code to correctly wrap the socket for HTTPS.

Raspberry Pi

import http.server
import ssl

httpd = http.server.HTTPServer(('0.0.0.0', 4443), http.server.SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket(httpd.socket, certfile='server.pem', keyfile=[1], server_side=True)
httpd.serve_forever()

Drag options to blanks, or click blank then click option'

A'server.key'

Bserver.key

C'server.pem'

D'key.pem'

💡 Hint

Common Mistakes

Passing the filename without quotes causing a NameError.

The keyfile parameter must be a string with the filename in quotes, like 'server.key'.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps domain names to their certificate expiration days.

Raspberry Pi

cert_days = {domain: [1] for domain, cert in certs.items() if cert.[2] > 0}

Drag options to blanks, or click blank then click option'

Acert.expiration_days

Bcert.expiry

Cexpiration_days

Ddays_left

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect attribute names that do not exist in the certificate object.

The dictionary comprehension uses cert.expiration_days to get days and checks if cert.expiry is positive.

5fill in blank

hard

Fill all three blanks to create a secure HTTPS server setup with certificate and key files.

Raspberry Pi

import http.server
import ssl

server_address = ('', 443)
httpd = http.server.HTTPServer(server_address, http.server.SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket(httpd.socket, keyfile=[1], certfile=[2], server_side=[3])
httpd.serve_forever()

Drag options to blanks, or click blank then click option'

A'server.key'

B'server.pem'

CTrue

DFalse

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect file names or forgetting to set server_side to True.

The keyfile is the private key file 'server.key', the certfile is the certificate file 'server.pem', and server_side must be True to enable server mode.
