From:
Operating system: Ubuntu 10.04 LTS
PHP version: 5.4.0RC4
Package: OpenSSL related
Bug Type: Bug
Bug description:openssl_seal fails with AES
Description:
------------
The following test script segfaults in both PHP 5.3.8 and PHP 5.4.0RC4 even
though OpenSSL is supposed to support AES in PHP 5.4.0.
In the attached script running with method 'aes256' or 'AES-256-CFB' both
segfault.
PHP 5.4.0 just prints a segfault, but in my PHP 5.3.8 from Zend Server, it
prints
a full printout first.
I don't know if this is an expected wontfix or if its a genuinely
overlooked
item.
Test script:
---------------
<?php
$pkey = openssl_pkey_new(array(
'digest_alg' => 'sha256',
'x509_extensions' => 'v3_ca',
'private_key_bits' => 4096,
'private_key_type' => OPENSSL_KEYTYPE_RSA,
'encrypt_key' => false
));
$details = openssl_pkey_get_details($pkey);
$Tpubkey = $details['key'];
$pubkey = openssl_pkey_get_public($Tpubkey);
$encrypted = null;
$ekeys = array();
$result = openssl_seal('test phrase', $encrypted, $ekeys, array($pubkey),
'aes256');
//$result = openssl_seal('test phrase', $encrypted, $ekeys, array($pubkey),
'AES-256-CFB');
Expected result:
----------------
I would expect encrypted text placed in $encrypted and AES encrypted
session keys
placed in $ekeys.
Actual result:
--------------
PHP 5.4.0
