More curves please

[MoezGholami]

Hi there,
It would be good if you implement more curves. Mainly, I'm speaking about secp521r1 as almost all SSL libraries have implemented it..
I wish I was not so new to Rust and ECC and I could contribute to this project. Nevertheless, I like the Gotham city project and I would appreciate a lot if some more trusted curves are implemented here.

Hi @MoezGholami ,
Thanks for this suggestion. secp521r1 can be interesting addition.
Do you happen to know a Rust implementation of this EC?

I did a quick search but couldn't find any.

Any cpp libraries maybe?
Curv uses existing implementations of ECs and build on top of them. Writing the low level code of secp521r1 is completely other game. We need to find a good library for the basic secp521r1 and than it can be on-boarded.

Omer, I found the openssl implementation of it here. However, there is a problem with this specific curve which make me to take my word back; according to this, it is not used at least for now. (The post is not new but it the recent comments are endorsing it).
According to that post secp384r1 seems a better choice. I tried to look its implementation up, I guess one example is this one.
