[Fedora-legal-list] Re: Is ECDSA secp256k1 elliptic curve permitted to be packaged in Fedora?

The package you linked includes secp256k1 and prime256v1.
secp256k1 seems to be OK.
For example, it is included in nettle, but it removes secp192r1 and secp224r1 from its
sources.
It is also included in openssl:
$ openssl ecparam -list_curves
secp224r1 : NIST/SECG curve over a 224 bit prime field
secp256k1 : SECG curve over a 256 bit prime field
secp384r1 : NIST/SECG curve over a 384 bit prime field
secp521r1 : NIST/SECG curve over a 521 bit prime field
prime256v1: X9.62/SECG curve over a 256 bit prime field
So it looks like the removal of secp192r1 and secp224r1 from nettle seems to be outdated,
because at least the latter curve is enabled in OpenSSL.
Wasn't there some kind of wiki page that listed elliptic curves which we weren't
allowed to ship? I can't seem to find it any longer, so it might have fallen victim to
the move of the Legal docs to GitLab ...
