Description:
------------
openssl_encrypt function refuse to encrypt data larger than key size.

Then I try, open_ssl_encrypt say :

> error:0406C06E:rsa routines:RSA_padding_add_PKCS1_type_1:data too
large for key size

Openssl support is enabled and I am using OpenSSL 0.9.7c 30 Sep 2003.

Reproduce code:
---------------
#GET PRIVATE KEY PREVIOUSLY GENERATED
$private_key =
openssl_get_privatekey('file:///var/tmp/pkey.pem','r0bert');

$data =
"abcdefghijiklmnopqrstuvwxyzabcdefghijiklmnopqrstuvwxyzabcdefghijiklmnopqrstuvwxyzabcdefghijiklmnopqrstuvwxyzabcdefghijiklmnopqrstuv";

openssl_private_encrypt($data, $crypted_text, $private_key);


Expected result:
----------------
I expect crypted data in $crypted_text.

Actual result:
--------------
error:0406C06E:rsa routines:RSA_padding_add_PKCS1_type_1:data too large
for key size
