Certificate Overview
    Valid Host Names - Matched www.visa.com, ...
    Expires - in one year - Valid after May 27, 2016
    Trust - Trusted - The certificate was issued by GeoTrust SSL CA - G3

Security
    Encryption Ciphers - OK -
    Public Key Size - 2048 bits - Key sizes 1024 bits or larger are considered
        secure. Be aware that unnecessarily large key sizes will slow down the
        connection establishment.
    Secure Renegotiation - Yes -
    Protocols - OK - SSLv3, TLSv1

Performance
    HTTP Keepalive - No - Enabling HTTP Keep-Alive will allow subsequent
        requests to be served faster, without the need to establish
        a new SSL/TLS connection.
    SSL Session Cache - Yes -
    TLS Stateless Resume - Yes
    SSL Handshake Size - 4410 bytes - The amount of data exchanged to
        establish a session with this server is large. This will result
        in a slower initial connection. Using a certificate with fewer
        intermediate chains and / or a smaller public key size can
        reduce the amount of data.

Encryption Ciphers (TLS/SSLv3)
    Cipher - Strength - Algo - Key - KeyEx - Handshake
    AES128-SHA - High - AES - 128-bit - RSA - 122ms - 4106 bytes
    ECDHE-RSA-AES128-SHA - High - AES - 128-bit - ECDH - 138ms - 4322 bytes
    DES-CBC3-SHA - High - 3DES - 168-bit - RSA - 117ms - 4090 bytes
    ECDHE-RSA-AES256-SHA - High - AES - 256-bit - ECDH - 112ms - 4322 bytes
