If you provide the data with the correct size, by appending "\0"s for example,
the function works. Now it's obvious, after two days of work. Maybe the
documentation should address that.

Description:
------------
openssl_public_encrypt fails with the argument OPENSSL_NO_PADDING. Without it,
it works fine.
Test script:
---------------
$configargs = array
("private_key_bits" => 4096,
"private_key_type" => OPENSSL_KEYTYPE_RSA,
"encrypt_key" => false);
$key = openssl_pkey_new($configargs);
$details = openssl_pkey_get_details($pubkey);
$pubkey = $details['key'];
$r = openssl_public_encrypt("This is a test", $crypted, $pubkey,
OPENSSL_NO_PADDING);
if ($r) {
echo "encrypt no padding: true\n";
} else {
echo "encrypt no padding: false\n";
$r = openssl_public_encrypt("This is a test", $crypted, $pubkey);
if ($r) {
echo "encrypt with padding: true\n";
} else {
echo "encrypt with padding: false\n";
}
}
Expected result:
----------------
encrypt no padding: true
Actual result:
--------------
encrypt no padding: false
encrypt with padding: true
------------------------------------------------------------------------
