类 Gem::Security::TrustDir

TrustDir 管理 gem 签名验证的受信任证书。

常量

DEFAULT_PERMISSIONS: 信任目录及其内容的默认权限

属性

dir [R]

存储受信任证书的目录。

公共类方法

new (dir, permissions = DEFAULT_PERMISSIONS)

源代码

# File lib/rubygems/security/trust_dir.rb, line 25
def initialize(dir, permissions = DEFAULT_PERMISSIONS)
  @dir = dir
  @permissions = permissions

  @digester = Gem::Security.create_digest
end

使用 dir 创建一个新的 TrustDir，其中目录和文件权限将根据 permissions 进行检查

公共实例方法

cert_path (certificate)

源代码

# File lib/rubygems/security/trust_dir.rb, line 35
def cert_path(certificate)
  name_path certificate.subject
end

返回受信任的 certificate 的路径

each_certificate () { |certificate, certificate_file| ... }

源代码

# File lib/rubygems/security/trust_dir.rb, line 42
def each_certificate
  return enum_for __method__ unless block_given?

  glob = File.join @dir, "*.pem"

  Dir[glob].each do |certificate_file|
    certificate = load_certificate certificate_file

    yield certificate, certificate_file
  rescue OpenSSL::X509::CertificateError
    next # HACK: warn
  end
end

枚举受信任的证书。

issuer_of (certificate)

源代码

# File lib/rubygems/security/trust_dir.rb, line 60
def issuer_of(certificate)
  path = name_path certificate.issuer

  return unless File.exist? path

  load_certificate path
end

如果给定 certificate 的颁发者证书存在于信任目录中，则返回该证书。

load_certificate (certificate_file)

源代码

# File lib/rubygems/security/trust_dir.rb, line 80
def load_certificate(certificate_file)
  pem = File.read certificate_file

  OpenSSL::X509::Certificate.new pem
end

加载给定的 certificate_file

name_path (name)

源代码

# File lib/rubygems/security/trust_dir.rb, line 71
def name_path(name)
  digest = @digester.hexdigest name.to_s

  File.join @dir, "cert-#{digest}.pem"
end

返回具有给定 ASN.1 name 的受信任证书的路径

trust_cert (certificate)

源代码

# File lib/rubygems/security/trust_dir.rb, line 89
def trust_cert(certificate)
  verify

  destination = cert_path certificate

  File.open destination, "wb", 0o600 do |io|
    io.write certificate.to_pem
    io.chmod(@permissions[:trusted_cert])
  end
end

将证书添加到受信任证书列表。

verify ()

源代码

# File lib/rubygems/security/trust_dir.rb, line 105
def verify
  require "fileutils"
  if File.exist? @dir
    raise Gem::Security::Exception,
      "trust directory #{@dir} is not a directory" unless
        File.directory? @dir

    FileUtils.chmod 0o700, @dir
  else
    FileUtils.mkdir_p @dir, mode: @permissions[:trust_dir]
  end
end

确保信任目录存在。如果它确实存在，请确保它实际上是一个目录。如果不是，则使用适当的权限创建它。
