  # when building OpenSSL from source we have a few challenges.
  # - AB uses Net::SSLeay (via HTTP::Tiny) by default when downloading https URLs
  # - Net::SSLeay requires OpenSSL
  # - We can download OpenSSL from FTP, but that is susceptible to man-in-the-middle attacks
  #   (and that is a bad look for a security product)

  # Solution:
  # - try downloading with curl or wget via the 'bootstrap_ssl' option.
  # - if that doesn't work, fallback on FTP
  # - don't attempt FTP transfer if ALIEN_OPENSSL_FTP is set to 0
