| (1) Clients that do not support Forward Secrecy (FS) are excluded when determining support for it. | |||
| (2) No support for virtual SSL hosting (SNI). Connects to the default site if the server uses SNI. | |||
| (3) Only first connection attempt simulated. Browsers sometimes retry with a lower protocol version. | |||
| (R) Denotes a reference browser or client, with which we expect better effective security. | |||
| (All) We use defaults, but some platforms do not use their best protocols and features (e.g., Java 6 & 7, older IE). | |||
| (All) Certificate trust is not checked in handshake simulation, we only perform TLS handshake. | |||
