commit 09e5eb48698d4fef2fc1031870de86c553b6bfaa
Author: Petr Menšík <pemensik@redhat.com>
Date:   Wed Mar 7 20:35:13 2018 +0100

commit ab303db70082db76ecf36493d0b82ef3e8750cad
Author: Petr Menšík <pemensik@redhat.com>
Date:   Wed Mar 7 18:11:10 2018 +0100

    Changed root key to be RSASHA256

    Change bad trusted key to be the same algorithm.

commit 88ab07c0e14cc71247e1f9d11a1ea832b64c1ee8
Author: Petr Menšík <pemensik@redhat.com>
Date:   Wed Mar 7 16:56:17 2018 +0100

    Change used key to not use hmac-md5

    Fix upforwd test, do not use hmac-md5

commit aec891571626f053acfb4d0a247240cbc21a84e9
Author: Petr Menšík <pemensik@redhat.com>
Date:   Wed Mar 7 15:54:11 2018 +0100

    Increase bitsize of DSA key to pass FIPS 140-2 mode.

commit bca8e164fa0d9aff2f946b8b4eb0f1f7e0bf6696
Author: Petr Menšík <pemensik@redhat.com>
Date:   Wed Mar 7 15:41:08 2018 +0100

    Fix tsig and rndc tests for disabled md5

    Use hmac-sha256 instead of hmac-md5.

commit 0d314c1ab6151aa13574a21ad22f28d3b7f42a67
Author: Petr Menšík <pemensik@redhat.com>
Date:   Wed Mar 7 13:21:00 2018 +0100

    Add md5 availability detection to featuretest

commit f389a918803e2853e4b55fed62765dc4a492e34f
Author: Petr Menšík <pemensik@redhat.com>
Date:   Wed Mar 7 10:44:23 2018 +0100

    Change tests to not use hmac-md5 algorithms if not required

    Use hmac-sha256 instead of default hmac-md5 for allow-query

Use DEFAULT_HMAC configured variable
