Description Bill Nottingham 2013-12-05 15:47:27 UTC 
Description of problem:

At least, I would assume that's what is in go/src/pkg/crypto/elliptic/.
In Fedora, we only ship certain reviewed curves.

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

1.2-1

How reproducible:

100%

Steps to Reproduce:
1. look at golang's crypto code

Actual results:

Hey, that looks like ECC, and it appears to have been always included.
Comment 1 Vincent Batts 2013-12-05 16:09:19 UTC 
This will take a bit of work/consideration on which curves are not allowed.

From just stdlib alone, the following libraries import from crypto/elliptic:
* crypto/ecdsa
* crypto/x509
 - also imports from crypto/ecdsa
* crypto/tls
 - also imports from crypto/ecdsa
 - also imports from crypto/x509
Comment 2 Vincent Batts 2013-12-05 16:13:43 UTC 
per http://golang.org/src/pkg/crypto/ecdsa/ecdsa.go, the ecdsa implementation is to spec of the Suite B guide for FIPS 186-3
Comment 9 Vincent Batts 2013-12-20 17:54:29 UTC 
I've pushed a patched build to rawhide, to bake for a bit. http://koji.fedoraproject.org/koji/buildinfo?buildID=485741

Comment 17 Daniel Walsh 2016-06-15 20:13:45 UTC 
Reopening this bug as this patch is now causing docker builds to fail.
Comment 18 Daniel Walsh 2016-06-15 20:16:30 UTC 
Can we revisit this decision, has anything changed in the last few years.  Can we implement just the elyptical curves that the NSA has licenses for?

I'm checking into this.
Comment 21 Antonio Murdaca 2016-06-17 08:33:20 UTC 
if this isn't doable, however we can use this patch:

Comment 22 Dan Williams 2016-08-26 14:53:56 UTC 
Any resolution on this?  Upstream Kubernetes no longer builds due to the same github.com/google/certificate-transparency/go/x509/x509.go issues.
Comment 26 Ken Stailey 2016-09-11 20:59:13 UTC 
This affects building Google Cloud Print CUPS proxy for Android.

Once I patched out the references to elliptic.P224 I was able to build gcp-connector-util and print from my Android smartphone.
Comment 31 Tom "spot" Callaway 2016-11-17 21:29:44 UTC 
The NIST P-224 curve is now permissible in Fedora. I'm rebuilding golang to enable it now.
Comment 32 Tom "spot" Callaway 2016-11-17 21:32:15 UTC 
This is now done in Fedora 25+. For other branches, I'll leave the changes to the maintainers.
