Take a look a the TRIGGERS section of Class::DBI. You seem to want to set before_create, before_set_$column, and select.

Personally, I solved a similar problem (specifically, saving passwords with SHA1 and a salt value) by overriding create. Then methods called check_passwd and new_passwd were created for checking passwords and getting a new password, respectivily. With SHA1, it's hard to get the orginal text back, so there was no point in trying to override password to get the plaintext version back. Instead, the methods provided would do everything you'd want a password object to do, which ends up being a better OO design anyway, since there is more encapsulation.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
