PHP itself does not have this extension.
Reply to discussion (solution)
RSA is probably there.
You said the algorithm has not heard of, but PHP is easy to extend a cryptographic algorithm
There are ready-made C + + source code on the Web, you can rewrite the PHP extension yourself
You can also translate it into PHP code
Don't be lazy, the source code of more than 20 K, how is not complicated where to go

The key is deployment, not all servers let you deploy extensions.
Translated into PHP code, I think this is to save it, ECC code involves a lot of low-level functions, such as random, and efficiency, ECC operation is very large, although more efficient than RSA.
Isn't that a weird one for you?
