Description Sahana Prasad 2023-04-20 02:29:44 UTC

Description of problem:
Currently brainpool curves in ECC are disabled.

After discussing with RH-legal, we are now permitted to allow Brainpool curves.
There is a request to enable Brainpool curves by customers like Samsung (attached customer case).

Changes as part of this bug, will therefore enable long brainpool curves in ECC by default. Short curves are still disabled as they are unsafe to be used.

Actual results:
Brainpool curves are disabled.

Expected results:
Brainpool curves (long) are enabled in ECC by default.

Setting a doc type, but we still need to fill the doc text.
