# Generate Private Key and Certificate using RSA 256 encryption (4096-bit key)
openssl req -x509 -newkey rsa:4096 -keyout privatekey.pem -out certificate.pem -days 365
# Alternatively, setting the "-newkey" parameter to "rsa:2048" will generate a 2048-bit key.

# Generate PKCS#12 (P12) file for cert; combines both key and certificate together
openssl pkcs12 -export -inkey privatekey.pem -in certificate.pem -out cert.pfx

# Generate SHA256 Fingerprint for Certificate and export to a file
openssl x509 -noout -fingerprint -sha256 -inform pem -in certificate.pem >> fingerprint.txt

###### PICK ONE OF THE TWO FOLLOWING ######

# OPTION ONE: RSA key. these are very well-supported around the internet.
# you can swap out 4096 for whatever RSA key size you want. this'll generate a key
# with password "xxxx" and then turn around and re-export it without a password,
# because genrsa doesn't work without a password of at least 4 characters.
#
# some appliance hardware only works w/2048 so if you're doing IOT keep that in

Here’s an example of an list comprehension in Haskell from Wikipedia:

a = [(x,y) | x <- [1..5], y <- [3..5]]
-- [(1,3),(1,4),(1,5),(2,3),(2,4) ...

In this example, a list of pair of integers is constructed from 2 lists of integers.

Here is what that example would be in Python:

<?php

function canView(string $scope, int $owner_id): bool
{
    return $scope === 'public' || $this->userCanView(Auth::user(), $owner_id);
}

function userCanView(User $user, int $owner_id): bool
{
    return $user->hasRole('admin') || $user->id === $owner_id;
