<div> Why the need for that complexity? The X509s are public by nature and don't need to be stored in Barbican so there isn't really a private part of the certificate. The actual private key itself is what needs to be secured so I would advocate that the
private key is what will be stored in barbican. I also think we should also declare that the private key need not be an RSA key as x509 supports other asymmetric encryption types so storing as a generic blob in barbican is probably a good idea.</div>

<span style="">Both VPN and LBaaS will use SSL certificates and keys, and this makes it better to implement SSL entities as first class citizens in the OS world. So, three points need to be discussed here:<o:p></o:p></span></div>

<span style="">1. The VPN SSL implementation above is putting the SSL cert content in a mapping table, instead of maintaining certs separately and referencing them using IDs. The LBaaS implementation stores certificates in a separate table, but implements the
necessary extensions and logic under LBaaS. We propose that both these implementations move away from this and refer to SSL entities using IDs, and that the SSL entities themselves are implemented as their own resources, serviced either by a core plugin or
a new SSL plugin (assuming neutron; please also see point 3 below).<o:p></o:p></span></div>

<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; ">
<span style="">2. The actual data store where the certs and keys are stored should be configurable at least globally, such that the SSL plugin code will singularly refer to that store alone when working with the SSL entities. The data store candidates currently
are Barbican and a sql db. Each should have a separate backend driver, along with the required config values. If further evaluation of Barbican shows that it fits all SSL needs, we should make it a priority over a sqldb driver.<o:p></o:p></span></div>

<div>
<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; ">
<span style=""> <o:p></o:p></span></div>
</div>
<div>
<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; ">
<span style="">3. Where should the primary entries for the SSL entities be stored? While the actual certs themselves will reside on Barbican or SQLdb, the entities themselves are currently being implemented in Neutron since they are being used/referenced there.
However, we feel that implementing them in keystone would be most appropriate. We could also follow a federated model where a subset of keys can reside on another service such as Neutron. We are fine with starting an initial implementation in neutron, in a
modular manner, and move it later to keystone.<o:p></o:p></span></div>
