PHP extension is wrapping ed25519, an Elliptic Curve Digital Signature Algortithm, developed by Dan Bernstein, Niels Duif, Tanja Lange, Peter Schwabe, and Bo-Yin Yang.
Thank you for this nice PHP extension. I use it for my project and it works well.
It may not be the good place to ask my questions as it is partially related to this extension.
Could it be possible to implement a method for the X25519 function to allow us to encrypt/decrypt using this curve?
As the IETF draft introduces the curves ed25519 and ed448 and you already implemented ed25519, could it be possible to create a similar project or update this one to provide the ed448 curve?
If you agree with the two previous points, could it be possible to implement a method for the X488 function as well?
