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
Every curve supported has to be explicitly acked by Fedora legal. I suggest you to contact Fedora legal for details.
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.
Curve25519 is now enabled.
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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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.
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.
Is there any update on this topic?
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.
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.
This package has changed maintainer in the Fedora. Reassigning to the new maintainer of this component.
See https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/message/ZWQUWUYR7VVG6EXSXZYES5MWCWWKBNKG/
This was potentially in progress according to https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/message/3ESF4KDVMLQPZX4H2S4L7BP5BHJPMPMB/. Re-opening.
Removing FE-Legal. See: https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/message/752Z34MTHB6B4XRUW2TTAPEIUUK4O2LA/
Thanks Richard, Matthew, and all who worked behind the scenes to get to this point! I filed https://src.fedoraproject.org/rpms/libgcrypt/pull-request/9 to remove the disable-brainpool bits from libgcrypt.
Built in rawhide as https://koji.fedoraproject.org/koji/taskinfo?taskID=94009347 Thank you all for the work and Todd for the PR!
