Is the IPv6 firewall built into the home routers safe?

The MySQL AES_ENCRYPT function is insecure by default, as it uses ECB mode unless configured otherwise. The documentation provides an example of how to use CBC mode with a 256 bit key (though their example of a key is terrible): mysql> SET block_encryption_mode = 'aes-256-cbc'; mysql> SET @key_str = SHA2('My secret…
