使用Ruby中的SSLServer验证客户端证书

Question

下面是我用来设置服务器的代码:

require 'socket'
require 'openssl'

socket = TCPServer.new('127.0.0.1', 4433)

ssl_context = OpenSSL::SSL::SSLContext.new()
ssl_context.cert = OpenSSL::X509::Certificate.new(File.open("ssl/server/server.crt"))
ssl_context.key = OpenSSL::PKey::RSA.new(File.open("ssl/server/server.key"))

ca_cert = OpenSSL::X509::Certificate.new(File.open("ssl/ca/ca.crt"))

ssl_socket = OpenSSL::SSL::SSLServer.new(socket, ssl_context)

Thread.start(ssl_socket.accept) do |s|
    puts "Connected to #{s.peeraddr.last}"

    if s.peer_cert.verify(ca_cert.public_key)
        puts "Certificate verified"
    else
        puts "Certificate invalid"
    end
end

和客户:

require 'socket'
require 'openssl'

socket = TCPSocket.new('127.0.0.1', 4433)

ssl_context = OpenSSL::SSL::SSLContext.new
ssl_context.cert = OpenSSL::X509::Certificate.new(File.open("ssl/client1/client1.crt"))
ssl_context.key = OpenSSL::PKey::RSA.new(File.open("ssl/client1/client1.key"))

ssl_socket = OpenSSL::SSL::SSLSocket.new(socket, ssl_context)

ca_cert = OpenSSL::X509::Certificate.new(File.open("ssl/ca/ca.crt"))

ssl_socket.connect

if ssl_socket.peer_cert.verify(ca_cert.public_key)
    puts "Certificate checks out"
else
    puts "Certificate not verified"
end

但是,服务器在尝试获取无法找到的peer_cert时会抛出异常.有没有办法让SSLServer期望客户端证书？

在测试中查看test_client_auth和start_serverOpenSSL::SSL.

从我的头脑中,我在代码中看到的唯一一件事是您忘记在服务器端明确要求客户端身份验证 - 设置标志组合很重要

flags = OpenSSL::SSL::VERIFY_PEER|OpenSSL::SSL::VERIFY_FAIL_IF_NO_PEER_CERT
ctx.verify_mode = flags

这样服务器实际上将需要客户端身份验证,而不是静默接受未经身份验证的请求.如果您没有设置这些,服务器将很高兴,而不会请求客户端身份验证,因此也没有可用的对等证书.
