Well yes, the algorhythm does work on blocks. I was using an anology for every byte of a 2 MB file, because that would still be the realistic equivilent of 32 byte size blocks of a 64 MB file. I guess I
could put a max-restriction on the data that can be entered to encrypt.lol
The point is is that I HAVE to have each chunk of 32 chars from the file to work with...whether I am using an array or not. How how can I do something like this using substr as you suggest, or for that matter, ANY way without draining RAM!lol
sub get_data{
my(@chunks_of_32);
@chunks_of_32 = ();
open(FILE, $file) or die;
while(<FILE>){
push @chunks_of_32, /\d{32}/og;
}
close(FILE);
}
Thanks
