Subject: [PATCH 3/6] Adjust hash defaults based on system security level
Unlike the key-strength, this does not set a minimum level because
it's not a simple calculation. We will have to rely on libcrypto
rejecting any explicitly-set algorithms as a violation of policy.

Subject: [PATCH 8/8] Fix client-cert issues found by CI tests
Resolves: rhbz#1720667

Fix memory leak in sscg_sign_x509_csr()
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Address clang-analyzer warning
clang-analyzer determined that it was possible for the GET_BIO()
return value to have changed between conditional creation of the
client certificate and writing it out. This patch stores the result
of the lookup so it's certain to be consistent.

Fix wrong x509 version in CSR

process resulted in the certificates being generated with the
correct version. It's best to be correct anyway.

a bool may not be aligned properly. It was working prior to some

%description
A utility to aid in the creation of more secure "self-signed"
certificates. The certificates created by this tool are generated in a
way so as to create a CA certificate that can be safely imported into a
client machine to trust the service certificate without needing to set
up a full PKI environment and without exposing the machine to a risk of
false signatures from the service certificate.
