Instance Attribute Details

#servername_cb ⇒ Object

A callback invoked at connect time to distinguish between multiple server names.

The callback is invoked with an SSLSocket and a server name. The callback must return an SSLContext for the server name or nil.

def servername_cb
  @servername_cb
end

#tmp_dh_callback ⇒ Object

A callback invoked when DH parameters are required.

The callback is invoked with the Session for the key exchange, an flag indicating the use of an export cipher and the keylength required.

The callback must return an OpenSSL::PKey::DH instance of the correct key length.

Instance Method Details

#set_params(params = {}) ⇒ Object

Sets the parameters for this SSL context to the values in params. The keys in params must be assignment methods on SSLContext.

If the verify_mode is not VERIFY_NONE and ca_file, ca_path and cert_store are not set then the system default certificate store is used.
