Warning: openssl_encrypt(): error

Trying to build a new INSERT behavior using the encryption method I've used before, and I'm getting this message: Warning: openssl_encrypt(): Using an empty Initialization Vector (iv) is potentially insecure and not recommended in ... Why do you think this might be suddenly cropping up?

Additional info: If I remove the PHP error reporting, then the page processes as expected, though no salt seems to be inserted in the table. Not sure why?? I haven't built a page to test if the decrypt works yet.

This is a warning, and can be turned off on the top of the page. You can add this to the top of the page to remove the warning message and just ignore it: error_reporting(E_ERROR);

I'm curious why no salt value is being inserted into the table?

You could create and add a salt value. It is another level of complexity, but certainly another level of security as well if you need to be extra cautious with your data.

yes, we've done this before but it's not working right now. This might need to be a special ticket for your examination.

Give me a call... I'm sure we can figure it out pretty quickly.
