# This script uses yes to automatically answer 'y' to all prompts from ssh-keygen,
# effectively accepting the defaults.
# The options -t rsa specify the RSA key type, -b 2048 sets the key size to 2048 bits,
# -f ~/.ssh/id_rsa specifies the output file,
# -q runs in quiet mode,
# and -N "" sets an empty passphrase for the private key.
