This should be handled in your model.

my MyApp::Schema::User has the following methods:



sub crypt_password {
     shift;
     my $csh = Crypt::SaltedHash->new( algorithm => 'SHA-1' );
     $csh->add(shift);
     return $csh->generate;
}

sub store_column {
     my ( $self, $column, $value ) = @_;
     $value = $self->crypt_password($value)
       if ( $column eq "password"
         && defined $value);
     return $self->next::method( $column, $value );
}

this will crypt the password each time it is set to a new value. You  
have to change crypt_password to fit your needs.

store_column is a dbic method so you have to make sure to call  
next::method in there.
