You can install "curl"

sudo apt-get install curl libcurl3 libcurl3-dev php5-curl

and then install Composer 

curl -sS https://getcomposer.org/installer | php

'sudo' is not recognized as an internal or external command, operable program or batch file.

Which operating system do you use?

Try without 'sudo', but with root privileges.

For Windows everything much easier - just download it from https://getcomposer.org/download/. Find "Windows Installer"

it says this when i'm trying to download: The openssl extension is missing, which means that secure HTTPS transfers are impossible.

How exactly are you trying to install now?

The windows installer is available at https://getcomposer.org/doc/00-intro.md#using-the-installer

Please try using that and following the concise instructions there.
