@jvdsn as a heads up, we cannot merge in PRs for this repository. We have an internal repository that we publish here when we have a release put together. We would need to incorporate these changes into that internal repository, and close out the PR. |
|
@celic that is fair, you are free to apply this change internally and publish it in a new server release. I simply want to see the issue resolved. I believe this change is so trivial it wouldn't even be copyrightable, but if it is I hereby release it in the public domain to be used or reproduced without any restrictions. |

This fix has been staged to be included in the next hotfix for deployment to ACVTS Demo. |

As shown in issue #305, the ACVP server doesn't handle AES-GCM-SIV decryption failures properly. The missing
result.TestPassed = false;seems to be the cause (compared to GCM: https://github.com/usnistgov/ACVP-Server/blob/master/gen-val/src/orleans/src/NIST.CVP.ACVTS.Libraries.Orleans.Grains/Aead/OracleObserverAesGcmCaseGrain.cs#L72-L76)Obviously this PR is untested on my end, considering I don't have an ACVP server :)
Note that this bug is also present in https://github.com/usnistgov/ACVP-Server/blob/master/gen-val/json-files/ACVP-AES-GCM-SIV-1.0/ as explained in the aforementioned issue. Those files would need to be updated.
