php 5.6 ssl证书验证

Question

我正在尝试使用ssl证书验证调试问题,并确定openssl获取返回错误路径的证书位置.(见下文)

我如何弄清楚如何设置它？我查看了php.ini文件,无法在任何地方找到此引用.

cmuench-air:bin cmuench$ ./php -r "print_r(openssl_get_cert_locations());"
Array
(
    [default_cert_file] => /bitnami/mampstack56Dev-osx-x64/output/common/openssl/cert.pem
    [default_cert_file_env] => SSL_CERT_FILE
    [default_cert_dir] => /bitnami/mampstack56Dev-osx-x64/output/common/openssl/certs
    [default_cert_dir_env] => SSL_CERT_DIR
    [default_private_dir] => /bitnami/mampstack56Dev-osx-x64/output/common/openssl/private
    [default_default_cert_area] => /bitnami/mampstack56Dev-osx-x64/output/common/openssl
    [ini_cafile] => 
    [ini_capath] => 
)

php.ini(相关部分)...我在任何地方都看不到bitnami/mampstack56Dev ......

编辑:

我知道这很愚蠢,但有时候ssl证书会自行签名.是否有一个ini设置我可以修改以禁用检查所有证书？或者我是否必须在套接字和卷曲的代码中执行此操作？

如果检查openssl_get_cert_locations()函数的PHP源代码,它将通过调用各种OpenSSL函数来获取这些位置,例如X509_get_default_cert_file查看php.ini值openssl.cafile并在此处进行openssl.capath描述.

您正在寻找哪些证书/路径？如果您尝试获取CA捆绑文件,则可以设置上面引用的php.ini值,以便返回它们openssl_get_cert_locations.

php.iniPHP 5.6 的默认文件没有针对那些OpenSSL ini设置的默认设置,因为它们需要手动定义.此配置位于附近php.ini

使用cURL时,如果要禁用证书验证,可以将这些选项传递给curl_setopt():

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);  // shouldn't need this

CURLOPT_SSL_VERIFYPEER 被描述为:

FALSE阻止cURL验证对等方的证书.可以使用CURLOPT_CAINFO选项指定要验证的备用证书,也可以使用CURLOPT_CAPATH选项指定证书目录.

CURLOPT_SSL_VERIFYHOST 被描述为:

1检查SSL对等证书中是否存在公用名.2检查是否存在公用名,并验证它是否与提供的主机名匹配.在生产环境中,此选项的值应保持为2(默认值).

如果您有CA文件,则可以使用该选项CURLOPT_CAINFO提供包含一个或多个证书的文件的完整路径,以验证对等方.

要禁用检查打开的流fsockopen,请尝试:

<?php
$context = stream_context_create();
$result = stream_context_set_option($context, 'ssl', 'verify_peer', false);

$socket = stream_socket_client('ssl://'.$host . ':443', $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context); 

有关详细信息,请参阅SSL上下文选项stream_socket_client().
