I'm a newbie to Perl . I'm wading my way through CPAN trying to find some Perl modules for read/write operations on a structured file. I'm looking for something that will allow me to create an encrypted file and then maintain it using select,insert,update and delete operations on the records in that file. This is on unix. There seem to be a plethra of modules available but I don't know which are the best to start with. Can someone give me some pointers ?
