Ruby 1.8.7 and Net::HTTP: Making an SSL GET request with client cert?

Question

I'm trying to fetch a resource via SSL using Net::HTTP. Here is the relevant code fragment:

req = Net::HTTP::Get.new(ContentURI.path)
https = Net::HTTP.new(ContentURI.host, ContentURI.port)
https.use_ssl = true
https.cert = OpenSSL::X509::Certificate.new(@cert_raw)
https.key = OpenSSL::PKey::RSA.new(@cert_key_raw)
https.verify_mode = OpenSSL::SSL::VERIFY_PEER
https.ca_file = File.join(TestDataPath, 'cacert.pem')
resp = https.start { |cx| cx.request(req) }

or with the alternate last line:

resp = https.get(ContentURI.path)

I have verified that the various bits (cert, key, CA cert, etc.) are correct.

The problem is that the cx.request(req) throws an exception:

OpenSSL::SSL::SSLError: SSL_connect SYSCALL returned=5 errno=0 state=SSLv3 read server session ticket A

The Apache SSL error log on the server contains the following:

[Tue Jan 24 11:47:26 2012] [debug] ssl_engine_kernel.c(1876): OpenSSL: Loop: SSLv3 read finished A
[Tue Jan 24 11:47:26 2012] [debug] ssl_engine_kernel.c(1905): OpenSSL: Exit: error in SSLv3 write session ticket A
[Tue Jan 24 11:47:26 2012] [debug] ssl_engine_kernel.c(1905): OpenSSL: Exit: error in SSLv3 write session ticket A
[Tue Jan 24 11:47:26 2012] [info] [client 10.11.88.53] SSL handshake interrupted by system [Hint: Stop button pressed in browser?!]
[Tue Jan 24 11:47:26 2012] [info] [client 10.11.88.53] Connection closed to child 0 with abortive shutdown (server _SERVERNAME_:443

The cert, key, and CA cert file work with this SSL host through other tools; I'm just having trouble reproducing that success programatically using Net::HTTP[S].

Thanks to anyone who can identify what I'm doing wrong!

I'd say this is matter of your Apache setup rather than problem with Ruby itself.

Check this out:

$ curl https://palladium.wejn.cz/sslcerttest/
curl: (56) SSL read: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure, errno 0
$ curl https://palladium.wejn.cz/sslcerttest/ -E client.pem
<pre>Yop.</pre>

And then:

#!/usr/bin/ruby
require 'net/http'
require 'net/https'
require 'openssl'
require 'uri'

ContentURI = URI.parse("https://palladium.wejn.cz/sslcerttest/")
@cert_raw = File.read('client.pem')
@cert_key_raw = @cert_raw
TestDataPath = '.'

req = Net::HTTP::Get.new(ContentURI.path)
https = Net::HTTP.new(ContentURI.host, ContentURI.port)
https.use_ssl = true
https.cert = OpenSSL::X509::Certificate.new(@cert_raw)
https.key = OpenSSL::PKey::RSA.new(@cert_key_raw)
https.verify_mode = OpenSSL::SSL::VERIFY_PEER
https.ca_file = File.join(TestDataPath, 'cacert.pem')
resp = https.start { |cx| cx.request(req) }
p resp
p resp.body

results in:

$ ruby a.rb
#<Net::HTTPOK 200 OK readbody=true>
"<pre>Yop.</pre>\n"

$ dpkg -l ruby1.8 | tail -n1 | awk '{print $3}'
1.8.7.302-2squeeze1

$ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]

Of course, the apache config in question is:

<Directory /var/www/sslcerttest/>
    SSLVerifyClient require
    SSLVerifyDepth 5
    SSLCACertificateFile /var/www/sslcerttest/cacert.pem
    SSLCACertificatePath /var/www/sslcerttest/
    SSLOptions +FakeBasicAuth
    SSLRequireSSL
    SSLRequire %{SSL_CLIENT_S_DN_O} eq "Wejn s.r.o." and %{SSL_CLIENT_S_DN_OU} eq "Server Certificate"
</Directory>

Maybe posting additional details (apache config to test against) would be of some help when tracking this issue down...
