Ruby生成自签名证书

我试图用ruby生成一个自签名证书，但遇到了麻烦。这就是我现在拥有的：

require 'openssl'

if ARGV.length != 3 then
    puts "USAGE: #{__FILE__} <type[der|pem]> <private-out> <public-out>"
    exit
end

type = ARGV[0].downcase
privateKeyFile = ARGV[1]
publicKeyFile = ARGV[2]

values = [{ 'C' => 'US'},
          {'ST' => 'SomeState'},
          { 'L' => 'SomeCity'},
          { 'O' => 'Organization'},
          {'OU' => 'Organizational Unit'},
          {'CN' => "somesite.com"}]

name = values.collect{ |l| l.collect { |k, v| "/#{k}=#{v}" }.join }.join

key = OpenSSL::PKey::RSA.generate(1024)
pub = key.public_key
ca = OpenSSL::X509::Name.parse(name)
cert = OpenSSL::X509::Certificate.new
cert.version = 2 
cert.serial = 1 
cert.subject = ca
cert.issuer = ca
cert.public_key = pub 
cert.not_before = Time.now
cert.not_before = Time.now + (360 * 24 * 3600)

File.open(privateKeyFile + "." + type, "w") {|f| f.write key.send("to_#{type}") }
File.open(publicKeyFile + "." + type, "w") {|f| f.write cert.send("to_#{type}") }

这是我的证书上写的：

-----BEGIN CERTIFICATE-----
<lots of stuff>
-----END CERTIFICATE-----

提醒：我的目标是生成一个自签名证书，以防我冗长的问题在途中失去重点

---

编辑：我想真正的问题是如何使用密钥签署证书

我已经找到了几个非常好的使用OpenSSL示例的来源：

我还没有找到任何关于这方面的好文档，尽管我认为写下示例中的内容不会花费太长时间

---

我还从puppet源代码中找到了我想要的东西。希望这能帮助那些对ruby中缺少OpenSSL文档感到沮丧的人。

在

webrick/ssl

中有一个

create\u self\u signed\u cert

方法，它很容易理解，也很有用。

我直接从谷歌搜索中找到的代码中获取了一个帮助类。您需要的唯一依赖项是openssl gem（

gem安装openssl

）

用法：

my_cert = SelfSignedCertificate.new
puts "Private Key:\n#{my_cert.private_key}"
puts "Self-signed PEM:\n#{my_cert.self_signed_pem}"

Private Key:

啊。。。网络的短暂性。不到2年后，上述所有链接都被破坏。Puppet的源代码结构也发生了变化，但从他们的GitHub报告中可以收集到相同的一般信息：所有链接都被破坏了。任何人都会感兴趣我用ruby编写了csr示例，你可以在这里找到：你能提供一个使用示例吗？

cert，rsa=WEBrick:：Utils.create_self_signed_cert 1024、[[“CN”、“localhost”]]、“”

记住

需要“WEBrick/https”
