-= $RCSfile$ -- SSL/TLS enhancement for Net::HTTP.
-
-== Info
- 'OpenSSL for Ruby 2' project
- Copyright (C) 2001 GOTOU Yuuzou <gotoyuzo@notwork.org>
- All rights reserved.
-
-== Licence
- This program is licenced under the same licence as Ruby.
- (See the file 'LICENCE'.)
-
-== Requirements
- This program requires Net 1.2.0 or higher version.
- You can get it from RAA or Ruby's CVS repository.
-
-== Version
- $Id$
-
- 2001-11-06: Contiributed to Ruby/OpenSSL project.
- 2004-03-06: Some code is merged in to net/http.
-
-== Example
-
-Here is a simple HTTP client:
-
- require 'net/http'
- require 'uri'
-
- uri = URI.parse(ARGV[0] || 'http://localhost/')
- http = Net::HTTP.new(uri.host, uri.port)
- http.start {
- http.request_get(uri.path) {|res|
- print res.body
- }
- }
-
-It can be replaced by the following code:
-
- require 'net/https'
- require 'uri'
-
- uri = URI.parse(ARGV[0] || 'https://localhost/')
- http = Net::HTTP.new(uri.host, uri.port)
- http.use_ssl = true if uri.scheme == "https" # enable SSL/TLS
- http.start {
- http.request_get(uri.path) {|res|
- print res.body
- }
- }
-
-== class Net::HTTP
-
-=== Instance Methods
-
-: use_ssl?
- returns true if use SSL/TLS with HTTP.
-
-: use_ssl=((|true_or_false|))
- sets use_ssl.
-
-: peer_cert
- return the X.509 certificates the server presented.
-
-: key, key=((|key|))
- Sets an OpenSSL::PKey::RSA or OpenSSL::PKey::DSA object.
- (This method is appeared in Michal Rokos's OpenSSL extention.)
-
-: cert, cert=((|cert|))
- Sets an OpenSSL::X509::Certificate object as client certificate
- (This method is appeared in Michal Rokos's OpenSSL extention).
-
-: ca_file, ca_file=((|path|))
- Sets path of a CA certification file in PEM format.
- The file can contrain several CA certificats.
-
-: ca_path, ca_path=((|path|))
- Sets path of a CA certification directory containing certifications
- in PEM format.
-
-: verify_mode, verify_mode=((|mode|))
- Sets the flags for server the certification verification at
- begining of SSL/TLS session.
- OpenSSL::SSL::VERIFY_NONE or OpenSSL::SSL::VERIFY_PEER is acceptable.
-
-: verify_callback, verify_callback=((|proc|))
- Sets the verify callback for the server certification verification.
-
-: verify_depth, verify_depth=((|num|))
- Sets the maximum depth for the certificate chain verification.
-
-: cert_store, cert_store=((|store|))
- Sets the X509::Store to verify peer certificate.
-
-: ssl_timeout, ssl_timeout=((|sec|))
- Sets the SSL timeout seconds.
