# Referenced this stackoverflow answer by John1024: https://stackoverflow.com/a/28353785/2372698
uptime -p >/dev/null 2>&1
if [ "$?" -eq 0 ]; then
# Supports most Linux distro
# when the machine is up for less than '0' minutes then
# 'uptime -p' returns ONLY 'up', so we need to set a default value

Private/Public key Creation

# Generate a new RSA 4096bit(default is 2048bits) key
# and encrypt it with a passphrase based on AES CBC 256 cipher:
openssl genrsa -aes256 -out private_key.pem 4096

# Generate a new RSA 4096bit(default is 2048bits) key without a passphrase:
openssl genrsa -out private_key.pem 4096
