It's not possible to generate private keys using elliptic curve cryptography.

Expected result:
Attached is a patch for svn trunk to implement basic support for ec.

In order to determine which specific curve to use I've expanded the configuration array with a new key "ec_group_name". There's no openssl.conf equivalent (or at least I don't know).
If you prefer an other name or method to pass the curve name to the methods just drop me a note.

Additional I've added a new method openssl_get_curve_names() which gets a list of all available elliptic curves (their short names only).

Has this been added?  I see this is over 2 years old but I am getting "Unsupported private key type" with the following code:

		$config = array(
			"private_key_type" => OPENSSL_KEYTYPE_EC,
		$res = openssl_pkey_new($config);

This is needed to implement the Web Push protocol in PHP:

Is it possible to add this feature to PHP 7.0. Probably it will take some time to release stable version of PHP 7.1. We need this feature to send web push notification via PHP. There are some altenative libraries but they do it so slow. (around 1 second per encryption) and It's take too much time if we try to send mass push notification messages.

Thanks in advance,
