试图通过SSL创建一个简单的Ruby服务器

Question

我试图在Ruby中创建一个简单的SSL客户端和服务器.但我收到一个神秘的错误消息,文档没有任何帮助.

这是我的服务器代码:

#!/usr/bin/ruby

require "gserver"
require "openssl"

listeningPort = Integer(ARGV[0])

class Server < GServer
  def initialize(listeningPort)
    @sslContext = OpenSSL::SSL::SSLContext.new
    @sslContext.cert = OpenSSL::X509::Certificate.new(File.open("MyCert.pem"))
    super(listeningPort, "0.0.0.0")
  end
  def serve(io)
    begin
      ssl = OpenSSL::SSL::SSLSocket.new(io, @sslContext)
      ssl.sync_close = true
      ssl.connect
      while (lineIn = ssl.gets)
        lineIn = lineIn.chomp
        $stdout.puts "=> " + lineIn
        lineOut = "You said: " + lineIn
        $stdout.puts "<= " + lineOut
        ssl.puts lineOut
      end
    rescue
      $stderr.puts $!
    end
  end
end

server = Server.new(listeningPort)
server.start
server.join

客户端代码类似:

#!/usr/bin/ruby

require "socket"
require "thread"
require "openssl"

host = ARGV[0]
port = Integer(ARGV[1])

socket = TCPSocket.new(host, port)
sslContext = OpenSSL::SSL::SSLContext.new
sslContext.cert = OpenSSL::X509::Certificate.new(File.open("MyCert.pem"))
ssl = OpenSSL::SSL::SSLSocket.new(socket, sslContext)
ssl.sync_close = true
ssl.connect
puts ssl.peer_cert   # this is nil

Thread.new {
  begin
    while lineIn = ssl.gets
      lineIn = lineIn.chomp
      $stdout.puts lineIn
    end
  rescue
    $stderr.puts "Error in input loop: " + $!
  end
}

while (lineOut = $stdin.gets)
  lineOut = lineOut.chomp
  ssl.puts lineOut
end

当我连接时,我在服务器和客户端都收到此错误:

in `connect': SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: unknown protocol (OpenSSL::SSL::SSLError)

问题可能是它不信任证书(自签名).我不知道如何告诉客户信任该证书.上面,我已将服务器的证书放在上下文中,但这只是在黑暗中拍摄的.我甚至不确定我的证书是否采用可接受的格式(它在base64中,带有证书和文件中的私钥).文档很少,这个领域的网络似乎也不多.

有任何想法吗？

Answer 1

我想通了,这要归功于一些体面的文档链接.

首先,SSLSocket.connect()仅用于在客户端上调用.

但主要问题是我正在尝试使用GServer套接字并将其升级到SSL.相反,我应该使用OpenSSL :: SSL :: SSLServer.

另外,我将证书和私钥分成两个文件.

这是工作服务器:

#!/usr/bin/ruby

require "socket"
require "openssl"
require "thread"

listeningPort = Integer(ARGV[0])

server = TCPServer.new(listeningPort)
sslContext = OpenSSL::SSL::SSLContext.new
sslContext.cert = OpenSSL::X509::Certificate.new(File.open("cert.pem"))
sslContext.key = OpenSSL::PKey::RSA.new(File.open("priv.pem"))
sslServer = OpenSSL::SSL::SSLServer.new(server, sslContext)

puts "Listening on port #{listeningPort}"

loop do
  connection = sslServer.accept
  Thread.new {
    begin
      while (lineIn = connection.gets)
        lineIn = lineIn.chomp
        $stdout.puts "=> " + lineIn
        lineOut = "You said: " + lineIn
        $stdout.puts "<= " + lineOut
        connection.puts lineOut
      end
    rescue
      $stderr.puts $!
    end
  }
end

和客户:

#!/usr/bin/ruby

require "socket"
require "thread"
require "openssl"

host = ARGV[0]
port = Integer(ARGV[1])

socket = TCPSocket.new(host, port)
expectedCert = OpenSSL::X509::Certificate.new(File.open("cert.pem"))
ssl = OpenSSL::SSL::SSLSocket.new(socket)
ssl.sync_close = true
ssl.connect
if ssl.peer_cert.to_s != expectedCert.to_s
  stderrr.puts "Unexpected certificate"
  exit(1)
end

Thread.new {
  begin
    while lineIn = ssl.gets
      lineIn = lineIn.chomp
      $stdout.puts lineIn
    end
  rescue
    $stderr.puts "Error in input loop: " + $!
  end
}

while (lineOut = $stdin.gets)
  lineOut = lineOut.chomp
  ssl.puts lineOut
end
