I got those commands on irb
require 'mechanize'
agent = Mechanize.new
agent.get('https://monabo.lemonde.fr/customer/account/forgotpassword/')
I got this error:
OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=unknown state: sslv3 alert handshake failure
I tried on mac, and it works I don't have this error. However, it doesn't work on my computer (running Linux Mint 17).
What I tried:
Exporting this variable:
export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crtSetting this variable:
agent.agent.http.ca_file = '/etc/ssl/certs/ca-certificates.crt'Setting this:
OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONEChanging ruby version (I'm currently using ruby 2.1.5p275)
None of those solutions changed the issue. I suspect that the server is requiring a specific verson of OpenSSL.
Please notice that I can request https://google.com with mechanize and that it works, but not https://monabo.lemonde.fr/customer/account/forgotpassword/.
The fact that it works on mac may suppose that I got a wrong config.
EDIT: Here is the output of this command:
➜ swiff git:(master) ✗ openssl s_client -connect monabo.lemonde.fr/customer/account/forgotpassword:443 -tls1 -servername monabo.lemonde.fr/customer/account/forgotpassword | openssl x509 -text -noout

140045809014432:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: TRUSTED CERTIFICATE
Some other data:
The server supports only SSLv3 and TLSv1 and only with the cipher DES-CBC3-SHA. This cipher is not included in the default cipher set used by your version of ruby, as you can see in https://github.com/ruby/ruby/blob/ruby_2_1/ext/openssl/lib/openssl/ssl.rb. This setting is strange because from what I know DES-CBC3-SHA (i.e. DES3) is considered more secure then RC4-SHA which they have in their cipher set.
I've tried to find a way to set the ciphers for the mechanize object but I don't know much about writing ruby and also only have an older version of ruby on the system. You might try something like agent.agent.http.ciphers = [ 'des-cbc3-sha' ] or ask some ruby experts.
openssl s_client -connect monabo.lemonde.fr/customer/account/forgotpassword:443 -tls1 -servername monabo.lemonde.fr/customer/account/forgotpassword | openssl x509 -text -noout
From the outside world, I am able to connect. I can resolve the "unable to get local issuer certificate" error below by using -CApath with the OpenSSL command (exercise left to the reader since its not the problem).
This may help you with trouble shooting....

Installing the certified gem fixed this issue for me, with the following version of ruby/rubygems on Windows 7.

For Ruby < 2.5
You can add your cipher to the list of default ciphers:
OpenSSL::SSL::SSLContext::DEFAULT_PARAMS[:ciphers] += ':DES-CBC3-SHA'
then:
require 'mechanize'
agent = Mechanize.new
agent.get 'https://monabo.lemonde.fr/customer/account/forgotpassword/'
I don't know anything about ruby but the problem looks to do a certificate chain verification problem.
i.e. the openssl error "verify error:num=20:unable to get local issuer certificate"
is the reason for your failure.
The reason for the failure is that full chain can't be loaded. i.e. there is one or more missing certificates.
The first point is that the certificate chain given by the server is missing the intermediate. This really is a web server setup problem in that they are missing the intermediate certificate in there web server setup.
You can work around this problem by providing this intermediate in your local CA file. This is most likely the reason it works on your other machine, in that that machine's CA file contains the intermediate and the root certificates in your CA file.
I would check that you have both those certificates are in your CA file (/etc/ssl/certs/ca-certificates.crt), if not then add them. Once the openssl commands work without the "verify error:num=20:unable to get local issuer certificate" error then that will rule out that problem with your rudy code (assuming your rude code is using the same ca file).
If you can get the web server updated to use a certificate chain file that includes the server certificate and the intermediate certificate, that should also fix that problem as well.
