Constructor Details

.new(io) ⇒ `SSLSocket` .new(io, ctx) ⇒ `SSLSocket`

Creates a new ::OpenSSL::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 ::OpenSSL::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.

Class Method Details

.open(remote_host, remote_port, local_host = nil, local_port = nil, context: nil)

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 ::OpenSSL::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

#close_read

Close the stream for reading. This method is ignored by ::OpenSSL as there is no reasonable way to implement it, but exists for compatibility with ::IO.

[ GitHub ]

# File 'ext/openssl/lib/openssl/ssl.rb', line 465


def close_read
  # Unsupported and ignored.
  # Just don't read any more.
end

#close_write

Closes the stream for writing. The behavior of this method depends on the version of ::OpenSSL and the TLS protocol in use.

Sends a ‘close_notify’ alert to the peer.
Does not wait for the peer’s ‘close_notify’ alert in response.

In TLS 1.2 and earlier:

On receipt of a ‘close_notify’ alert, responds with a ‘close_notify’ alert of its own and close down the connection immediately, discarding any pending writes.

Therefore, on TLS 1.2, this method will cause the connection to be completely shut down. On TLS 1.3, the connection will remain open for reading only.

#sysclose ⇒ `nil`

Sends “close notify” to the peer and tries to shut down the ::OpenSSL::SSL connection gracefully.

If sync_close is set to true, the underlying ::IO is also closed.

#sysread(length) ⇒ `String` #sysread(length, buffer) ⇒ `buffer`

Reads length bytes from the ::OpenSSL::SSL connection. If a pre-allocated buffer is provided the data will be written into it.

#sysread_nonblock(length) ⇒ `String` (private) #sysread_nonblock(length, buffer) ⇒ `buffer` #sysread_nonblock(length[, buffer [, opts]) ⇒ `buffer`

A non-blocking version of #sysread. Raises an SSLError if reading would block. If “exception: false” is passed, this method returns a symbol of :wait_readable, :wait_writable, or nil, rather than raising an exception.

Reads length bytes from the ::OpenSSL::SSL connection. If a pre-allocated buffer is provided the data will be written into it.
