class DRb::DRbSSLSocket::SSLConfig

A convenience method to access the values like a Hash

def [](key);
  @config[key] || DEFAULT[key]
end

configuration
Accept connection to IO +tcp+, with context of the current certificate

def accept(tcp)
  ssl = OpenSSL::SSL::SSLSocket.new(tcp, @ssl_ctx)
  ssl.sync = true
  ssl.accept
  ssl
end

configuration
Connect to IO +tcp+, with context of the current certificate

def connect(tcp)
  ssl = ::OpenSSL::SSL::SSLSocket.new(tcp, @ssl_ctx)
  ssl.sync = true
  ssl.connect
  ssl
end

c.setup_certificate
})
:SSLCertName => [["CN" => DRb::DRbSSLSocket.getservername]]
c = DRb::DRbSSLSocket::SSLConfig.new({
require 'drb/ssl'

or

c.setup_certificate
c[:SSLCACertificatePath] = "/etc/ssl/certs/"
c[:SSLVerifyMode] = OpenSSL::SSL::VERIFY_PEER
c[:SSLPrivateKey] = OpenSSL::PKey::RSA.new(File.read('mycert.key'))
OpenSSL::X509::Certificate.new(File.read('mycert.crt'))
c[:SSLCertificate] =
c = DRb::DRbSSLSocket::SSLConfig.new {}
require 'drb/ssl'

These values can be added after the fact, like a Hash.
