I've never written anything in PHP here so I might be way off...But a 16MB memory limitation would only stop you from reading the entire file into memory at once. The way I'd do would be to read/encrypt/write N blocks at a time. [This is similar in principle to what you're doing, except without the need for separate files or reinitialization of the block cipher mode.]
-- Roscoe Received on Nov 10 2008Sorry for the late answer. You are right. I can do it your way but there is still another problem. PHP scripts normally timeout after 30seconds due to security reasons. So, I cannot encrypt/decrypt large files. Because of that I split the file.
