Just stating the obvious, you probably want to make sure that the encrypted data doesn't contain end-of-line characters or your delimiter | anywhere.

    That really shouldn't make any difference. What he'd essentially have is a two element row that the second element of which requires further processing. 

    my( $group, $data ) = split( /\|/, $_, 2 );
if( user_can_see( $group ) ) {
  my @data = split( /\|/, decrypt( $group, $data ) );
  process_row( @data );
}
