Decrypt and encrypt returns false

Keywords the weary google travellers, my colleague was having these errors locally for months, while I was not having them at all. It makes sense now I see that GovCMS updated to real_aes 2.5 when he started having the issues. It turns out that the reason I wasn't having these issues because of this in my local settings.php.

$config['tfa.settings']['reset_pass_skip_enabled'] = TRUE;
$config['tfa.settings']['enabled'] = FALSE;
