encoding / decoding data in models

[eluser]cellulit[/eluser]
hi guys;

i'm just wondering if there's any smart way to encrypt or decrypt results sets provided by db->get or get_where functions. i try to stick to the model and do this basic data manipulation there (instead of decrypting data in view for example).

so far, i've tried a couple of things including:

Code:

array_walk($results,'$this->encrypt->decode');

... but none of my attempts are successful.
any hints?

thanks in advance!
