openssl_csr_get_subject

(PHP 5 >= 5.2.0, PHP 7)

openssl_csr_get_subjectReturns the subject of a CSR

Descrierea

array openssl_csr_get_subject ( mixed $csr [, bool $use_shortnames = true ] )

openssl_csr_get_subject() returns subject distinguished name information encoded in the csr including fields commonName (CN), organizationName (O), countryName (C) etc.

Parametri

csr

See CSR parameters for a list of valid values.

use_shortnames

shortnames controls how the data is indexed in the array - if shortnames is TRUE (the default) then fields will be indexed with the short name form, otherwise, the long name form will be used - e.g.: CN is the shortname form of commonName.

Valorile întoarse

Exemple

Example #1 openssl_csr_get_subject() example

<?php
$subject 
= array(
    
"countryName" => "CA",
    
"stateOrProvinceName" => "Alberta",
    
"localityName" => "Calgary",
    
"organizationName" => "XYZ Widgets Inc",
    
"organizationalUnitName" => "PHP Documentation Team",
    
"commonName" => "Wez Furlong",
    
"emailAddress" => "wez@example.com",
);
$private_key openssl_pkey_new(array(
    
"private_key_bits" => 2048,
    
"private_key_type" => OPENSSL_KEYTYPE_RSA,
));
$configargs = array(
    
'digest_alg' => 'sha512WithRSAEncryption'
);
$csr openssl_csr_new($subject$privkey$configargs);
print_r(openssl_csr_get_subject($csr));
?>

Exemplul de mai sus va afișa ceva similar cu:

Array
(
    [C] => CA
    [ST] => Alberta
    [L] => Calgary
    [O] => XYZ Widgets Inc
    [OU] => PHP Documentation Team
    [CN] => Wez Furlong
    [emailAddress] => wez@example.com
)

This function may not return name fields in the order they appear in the certificate.  For example, this CSR:

-----BEGIN CERTIFICATE REQUEST-----
MIHsMIGUAgEAMDIxEDAOBgNVBAsMB3VuaXQgIzExDDAKBgNVBAoMA29yZzEQMA4G
A1UECwwHdW5pdCAjMjBZMBMGByqGSM49AgEGCCqGSM49AwEHA0IABGvZnFxGuVzJ
hOKPs5RNxZBS4vY6ERaqm5tKMGOhxLSfv/dpjDtNNdSHkIGNjYxclHYhxG0ku7BY
PA5uPIjng1SgADAKBggqhkjOPQQDAgNHADBEAiB4GXhhbEU1UFTCe0dwJnKHTQuI
xzYL5FnyhmKdixN/0gIgBXSm9S8L/oJ6rBxemin/V/xKv5jy4TEZuz84nnshxQQ=
-----END CERTIFICATE REQUEST-----

When processed by 'openssl -noout -subject' gives this:

subject=/OU=unit #1/O=org/OU=unit #2

On the other hand, 'var_dump( openssl_csr_get_subject( "..." ) )' will produce this:

csr = array(2) {
  ["OU"]=>
  array(2) {
    [0]=>
    string(7) "unit #1"
    [1]=>
    string(7) "unit #2"
  }
  ["O"]=>
  string(3) "org"
}

As you can see, ordering information (which may be important for some applications) is lost.

this function does not yet return SANs (subject alternative names) fields for UC certificates like those used in exchange 2007.

The returning assoziative array is indexed with the fields
in the subject so you should have a array key named CN,OU and so on.
