Creates a new SSL socket from io which must be a real IO object (not an IO-like object that responds to read/write).
If ctx is provided the SSL Sockets initial params will be taken from the context.
The OpenSSL::Buffering module provides additional IO methods.
This method will freeze the SSLContext if one is provided; however, session management is still allowed in the frozen SSLContext.

end
Creates a new instance of SSLSocket. remotehost_ and remoteport_ are used to open TCPSocket. If localhost_ and localport_ are specified, then those parameters are used on the local end to establish the connection. If context is provided, the SSL Sockets initial params will be taken from the context.
Examples
sock = OpenSSL::SSL::SSLSocket.open('localhost', 443) sock.connect # Initiates a connection to localhost:443
with SSLContext:
ctx = OpenSSL::SSL::SSLContext.new sock = OpenSSL::SSL::SSLSocket.open('localhost', 443, context: ctx) sock.connect # Initiates a connection to localhost:443 with SSLContext
