hi,
Hi Martin.
i just discovered that nettle in fedora/centos does not include the secp192 and 224 curves.
this is not discovered during build, but instead just leads to a runtime error. (the installation succeeds despite the error)
That's a bit exotic, and would indicate that the declarations are still present in the <nettle/ecc-curve.h> header file.
Potentially fixed in git for Pike 8.0 and 8.1.
Thanks for the report.
