Description Stephen So 2017-01-16 14:31:31 UTC 
Description of problem:

When generating ECC keys in gpg using expert mode, only three elliptic curves are available. All the curves are NIST ones, which many believe are suspect.  Other curves are available in gnupg2 such as brainpool, Curve 25519, etc. but these are not available in the Fedora version of gnupg2

Version-Release number of selected component (if applicable):

gnupg2-2.1.13-2.fc25.x86_64

How reproducible:

Always

Steps to Reproduce:
1.  Generate a key using gpg2 in expert mode:  gpg2 --expert --full-gen-key
2.  Select ECC and ECC for the type of key
3.  See list of elliptic curves available.

Actual results:

Please select which elliptic curve you want:
   (3) NIST P-256
   (4) NIST P-384
   (5) NIST P-521

Expected results:

Please select which elliptic curve you want:
   (1) Curve 25519
   (2) NIST P-256
   (3) NIST P-384
   (4) NIST P-521
   (5) Brainpool P-256
   (6) Brainpool P-384
   (7) Brainpool P-512

Additional info:

The information and examples were given on the gnupg site  https://www.gnupg.org/faq/whats-new-in-2.1.html#ecc
Comment 1 Tomas Mraz 2017-01-16 14:58:17 UTC 
Every curve supported has to be explicitly acked by Fedora legal. I suggest you to contact Fedora legal for details.
Comment 2 Tom "spot" Callaway 2017-01-16 15:36:57 UTC 
There isn't anything we can do about the Brainpool curves right now, but 25519 should be fine to enable in libgcrypt in all targets (it's on in rawhide right now). I think once that happens, you should be able to rebuild gnupg2 to see that additional curve option.
Comment 3 Tomas Mraz 2017-08-17 07:06:40 UTC 
Curve25519 is now enabled.
Comment 4 Fedora End Of Life 2017-11-16 19:51:25 UTC 
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '25'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Comment 5 Fedora End Of Life 2017-12-12 10:55:17 UTC 
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

(In reply to Tomas Mraz from comment #3)
> Curve25519 is now enabled.

I guess we should reopen this ticket because Brainpool is still missing.
Comment 7 Timothée Ravier 2018-09-22 09:21:54 UTC 
Is there any update on this topic?
Comment 8 Martin Schanzenbach 2020-11-09 20:31:14 UTC 
This is still an issue. It does not only affect key generation, but also verification of signatures and import of public keys of other users which have support and use it.
Comment 9 Timothée Ravier 2020-11-10 09:51:42 UTC 
I sent https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/thread/WUQNAB4EPWSJMMVECL2TZGKB5KIDESII/ to ask Fedora Legal to take a look at this issue.
Comment 10 Fedora Admin user for bugzilla script actions 2020-11-20 14:57:56 UTC 
This package has changed maintainer in the Fedora.
Reassigning to the new maintainer of this component.
Comment 11 Timothée Ravier 2021-07-07 11:29:46 UTC 
See https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/message/ZWQUWUYR7VVG6EXSXZYES5MWCWWKBNKG/
