Description:
------------
Enhancement request: Why does the
verify (http://us2.php.net/openssl_pkcs7_verify) command returns a boolean vs. the
string on success and false on error?  Currently, there is absolutely no way of getting the data out of signed block (i.e. application/(x-)pkcs7-mime block with smime-type=signed-data) with PHP functions.

And, come to think of it, openssl_pkcs_verify doesn't even return a boolean - as indicated by the documentation - since -1 is a possible return value.

Reproduce code:
---------------
e.g. this message data:

Content-Type: application/x-pkcs7-mime;
	smime-type=signed-data;
	name="smime.p7m"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
	filename="smime.p7m"

[signed data]

...may verify correctly (openssl_pkcs7_verify() returns true), but there is no way to retrieve the actual contents of the signed data.
