Question

您好我正在尝试从perl脚本获取SSL证书。主要目的是检查不受信任的SSL证书，如here所述。但我不确定如何继续。我没有可以检查证书的证书颁发机构，因此即使是有效证书sem的URL也会抛出错误。以下是我写的代码

#!/usr/bin/perl

require LWP::UserAgent;
use Crypt::SSLeay::CTX;
use Crypt::SSLeay::Conn;
use Crypt::SSLeay::X509;
use LWP::Simple qw(get);

$ENV{HTTPS_DEBUG} = 1;


my $ua  = LWP::UserAgent->new;
#$ua->ssl_opts(verify_hostname => "true");
$ua->timeout(300);
my $req = HTTP::Request->new(GET => 'https://abcdefxyz.com');

my $res = $ua->request($req);

print $res->headers_as_string . "\n" . $res->status_line;

我这样跑了

perl test2.pm＆gt; test

SSL_connect:before/connect initialization
SSL_connect:SSLv2/v3 write client hello A
SSL_connect:SSLv3 read server hello A
SSL_connect:SSLv3 read server certificate A
SSL_connect:SSLv3 read server key exchange A
SSL_connect:SSLv3 read server done A
SSL_connect:SSLv3 write client key exchange A
SSL_connect:SSLv3 write change cipher spec A
SSL_connect:SSLv3 write finished A
SSL_connect:SSLv3 flush data
SSL_connect:SSLv3 read finished A

这是同样的输出。

在没有本地CA文件的情况下，我是否仍然可以获取证书的SSL错误类型。我是这里的新手和perl，所以非常感谢有用的见解。

Answer 1

升级到LWP::Protocol::https的最新版本。这将自动引入适当的依赖关系，例如，最近的IO::Socket::SSL和Mozilla::CA。 LWP v6引入了自动验证CA签名。

您可以制作自己的证书，这些证书都是有效的，有效的CA签名和各种无效证书。请参阅OpenSSL文档中的How do I create a real SSL Certificate? in the Apache httpd documentation，Creating your own CA with OpenSSL（稍微过时）以及rsa和CA.pl联机帮助页。
