For further details and definitions of the PHP_INI_* modes, see the Where a configuration setting may be set.

Here's a short explanation of the configuration directives.

openssl.cafile string

Location of Certificate Authority file on local filesystem which should be used with the verify_peer context option to authenticate the identity of the remote peer.

openssl.capath string

If cafile is not specified or if the certificate is not found there, the directory pointed to by capath is searched for a suitable certificate. capath must be a correctly hashed certificate directory.

See also the SSL stream context options.

in capath the Certificates must be placed with the certificates hash as name and .0 as Ending.

Here is how to get the hashes from Certificates lying in this folder and automatically rename them in a correct way:
<?php
    $paths
=openssl_get_cert_locations();
   
$allowed=array("cer","crt","pem");
    if (!empty(
$paths['ini_capath'])){
       
$capathDirectory = dir($paths['ini_capath']);
        while (
false !== ($entry = $capathDirectory->read())) {
           
$Sourcefile=$paths['ini_capath']."/".$entry;
            if (
file_exists( $Sourcefile)){
               
$path_parts = pathinfo($Sourcefile);
                if (
in_array(strtolower($path_parts['extension']),$allowed)){
                   
$ParsedCertificatePbject = openssl_x509_parse(file_get_contents($Sourcefile));
                   
$Sourcefile= $ParsedCertificatePbject["hash"].".0";
                   
$TargetFilename = dirname($Sourcefile)."/".$Sourcefile;
                    if (!
file_exists($TargetFilename)) {
                       
rename ($Sourcefile ,$TargetFilename);
                    }
                }
            }
        }
       
$capathDirectory->close();
    }
?>

Hashed directory bedeutet die Dateinamen müssen mit dem Openssl hash, den ihr mittels openssl_x509_parse im Wert hash bekommt (Name) + die Dateiendung 0.
Bei doppelten HASH werten wird die Dateiendung incrementiert.
