Why use “recommended” elliptic curves?

302 views

Why do there need to be “recommended” elliptic curves? If “recommended” ones are just ones that someone has found a shortcut for, why isn’t it better to just choose a new random one each time? Is it that decrypting or validating different curves requires different specific code?

A couple of ECs that came out of NIST are considered compromised due to the NSA and not recommended for use.
