How encrypt with vector

Make sure that you are using the library version it has OpenSSL driver.

From viewing the library they are doing the vector using the key.

PHP Code:

$key = openssl_random_pseudo_bytes($length, $is_secure); 


As you can see above.

The vector is from what I read just the length of the key.

What did you Try? What did you Get? What did you Expect?
