I can not find how to configure ssl or tls protocols and ciphers in glance-api.conf. The only real reference to enabling ssl is by adding this:

[DEFAULT]
cert_file=/etc/pki/tls/certs/glance.crt
key_file=/etc/pki/tls/private/glance.key
ca_file=/etc/pki/tls/certs/glance_ca.crt

But how can I control what protocols and chiphers are used?
