Ruby生成自签名证书-Java 学习之路

我正在尝试在ruby中生成自签名证书，但遇到了麻烦 . 这就是我现在所拥有的：

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}") }

当我尝试在apache中使用生成的私钥和证书时，我收到此错误：

[Thu Mar 04 10:58:44 2010] [error] Init: Unable to read server certificate from file /etc/ssl/certs/gnarly.pem
[Thu Mar 04 10:58:44 2010] [error] SSL Library Error: 218529960 error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag
[Thu Mar 04 10:58:44 2010] [error] SSL Library Error: 218595386 error:0D07803A:asn1 encoding routines:ASN1_ITEM_EX_D2I:nested asn1 error

这是我的证书所说的：

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

它自称为证书而不是CSR，这就是我在网上找到的大部分内容都说明了apache2错误（我可能已经将CSR和CERT混淆了） . 我的猜测是我没有生成正确类型的证书 . 也许我必须更改序列或版本属性 . 另外，我不会在任何地方进行任何自我签名，而不是我所知道的 . 我知道你可以这样做：

require "openssl"
key = OpenSSL::PKey::RSA.generate(1024)
signature = key.sign(OpenSSL::Digest::SHA1.new, "data to sign")

提醒：我的目标是生成一个自签名证书，以防我的长期问题失去焦点 .

编辑：我想真正的问题是如何用密钥签署证书

我从我在Google搜索中找到的直接从nickyp's gist提取的代码创建了一个帮助类 . 你需要的唯一依赖是openssl gem（ gem install openssl ）

require 'openssl'

class SelfSignedCertificate
  def initialize
    @key = OpenSSL::PKey::RSA.new(1024)
    public_key = @key.public_key

    subject = "/C=BE/O=Test/OU=Test/CN=Test"

    @cert = OpenSSL::X509::Certificate.new
    @cert.subject = @cert.issuer = OpenSSL::X509::Name.parse(subject)
    @cert.not_before = Time.now
    @cert.not_after = Time.now + 365 * 24 * 60 * 60
    @cert.public_key = public_key
    @cert.serial = 0x0
    @cert.version = 2

    ef = OpenSSL::X509::ExtensionFactory.new
    ef.subject_certificate = @cert
    ef.issuer_certificate = @cert
    @cert.extensions = [
        ef.create_extension("basicConstraints","CA:TRUE", true),
        ef.create_extension("subjectKeyIdentifier", "hash"),
    # ef.create_extension("keyUsage", "cRLSign,keyCertSign", true),
    ]
    @cert.add_extension ef.create_extension("authorityKeyIdentifier",
                                           "keyid:always,issuer:always")

    @cert.sign @key, OpenSSL::Digest::SHA1.new
  end

  def self_signed_pem
    @cert.to_pem
  end

  def private_key
    @key
  end
end

Usage:

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

Output:

Private Key:

webrick/ssl 中有一个 create_self_signed_cert 方法，它易于理解和有用 .

我已经使用OpenSSL找到了几个非常好的示例来源：

http://snippets.dzone.com/posts/show/6309

http://projects.reductivelabs.com/projects/puppet/repository/revisions/master/entry/lib/puppet/sslcertificates.rb

http://projects.reductivelabs.com/projects/puppet/repository/revisions/master/entry/lib/puppet/sslcertificates/ca.rb

http://projects.reductivelabs.com/projects/puppet/repository/revisions/master/entry/lib/puppet/sslcertificates/certificate.rb

我还没有找到任何好的文档，尽管我认为写下示例中的内容并不需要太长时间 .

我也想出了如何从puppet源代码中做我想做的事情 . 希望这可以帮助那些对ruby中缺少OpenSSL文档感到沮丧的人 .
