Returns the security level for the context.

See also OpenSSL::SSL::SSLContext#security_level=.

Sets the security level for the context. OpenSSL limits parameters according to the level. The “parameters” include: ciphersuites, curves, key sizes, certificate signature algorithms, protocol version and so on. For example, level 1 rejects parameters offering below 80 bits of security, such as ciphersuites using MD5 for the MAC or RSA keys shorter than 1024 bits.

Note that attempts to set such parameters with insufficient security are also blocked. You need to lower the level first.

This feature is not supported in OpenSSL < 1.1.0, and setting the level to other than 0 will raise NotImplementedError. Level 0 means everything is permitted, the same behavior as previous versions of OpenSSL.

See the manpage of SSL_CTX_set_security_level(3) for details.

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.

Initiates the SSL/TLS handshake as a server in non-blocking manner.

# emulates blocking accept
begin
  ssl.accept_nonblock
rescue IO::WaitReadable
  IO.select([s2])
  retry
rescue IO::WaitWritable
  IO.select(nil, [s2])
  retry
end

By specifying a keyword argument exception to false, you can indicate that accept_nonblock should not raise an IO::WaitReadable or IO::WaitWritable exception, but return the symbol :wait_readable or :wait_writable instead.

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 SSL connection. If a pre-allocated buffer is provided the data will be written into it.

The X509 certificate for this socket’s peer.

Returns the TCPServer passed to the SSLServer when initialized.

Returns the certificate which caused the error.
