从CRL列表中获取序列号

Question

我有一个revoked.crl证书吊销列表和一些条目。如何从中检索序列号。当我使用撤销方法时，它会返回条目数组，如 “#OpenSSL :: X509 ::撤销：0x007f944b1fd0d8”。谁能告诉我如何解析这个来获得确切的序列号？

尝试类似：

require "openssl" 

crl_filepath = "./path/to/mylist.crl" 
puts "PARSING CRL FILE #{crl_filepath} ..." 

crl = OpenSSL::X509::CRL::new(File.read(crl_filepath)) 
puts "... ISSUER: #{crl.issuer.to_s}" 
puts "... VERSION: #{crl.version.to_s}" 
puts "... LAST UPDATE: #{crl.last_update.to_s}" 
puts "... NEXT UPDATE: #{crl.next_update.to_s}" 

puts "INVESTIGATING FIRST CERTIFICATE..." 
r = crl.revoked.first # FYI this is an OpenSSL::X509::Revoked object 
puts "... SERIAL: #{r.serial.to_s}" 
puts "... TIME: #{r.time.to_s}" 
puts "... EXTENSIONS (#{r.extensions.count}):" 
r.extensions.each do |ext| 
    puts " ... #{ext.to_h}" 
end
