Bug description: openssl_pkcs7_verify returns FALSE for msg that *was* correct
Description:
------------
Context:
A message "msg.txt" was signed the 01-01-2005 with a certificate expired
the 03-03-2005. It is a valid signed message.
If the system date is 02-02-2005,the openssl_pkcs7_verify function applied
to this "msg.txt" returns TRUE. It means it is a valid message
If you change the system date to 04-04-2005 (date after the expiration
date of the certificate), the openssl_pkcs7_verify function applied to
this "msg.txt" returns FALSE! Without any other information.
But it is not correct because at the moment of the signature, it was
correct.
Reproduce code:
---------------
$filename="/tmp/msg.txt";
$lCertT=array("/tmp/certifdir","/tmp/certifdir/thawte_freemail.cer");
$tmp_cert = tempnam ("", "crt");
$res = openssl_pkcs7_verify($filename, 0, $tmp_cert, $lCertT);
if (!$res) {
echo("Digital Signature BAD!<br>\n");
}
else if ($res === -1) {
echo("Error ...");
}
else {
echo("Digital Signature OK!<br>\n");
$cert_info = openssl_x509_parse("file://$tmp_cert");
var_dump($cert_info);
}
Expected result:
----------------
We expect to have result independent of the current date.. or at least, to
have information that at the signature time, the message was correct but
was signed with a certificate that is expired today.
Another possibility could be: to foressen an extra parameter to the
function to pass the date of the validation.
If you check the same message with an e-mail client (e.g. thunderbird), it
will say that the message was correctly signed with a valid certificate...
whatever the current date is.
Actual result:
--------------
Validation result depends of the system date
