Free file encryption software?

yup and I do agree - thats why I use DM-Crypt with LUKS, 40 character password and am relatively confident that should deter a casual snooper.

Well I'm currently reading the user manual for Truecrypt. I'll definitely use it for my world domination plans. I like the idea of associating specific files, like some innocuous mp3, as well as the password in order to decrypt it. Also the second level plausible deniability with the hidden volume within the encrypted volume is pretty cool.

Then you'll also note that Winzip has NOT changed it's encryption method and implementation since that paper. And the password recovery statement I made is still valid for version 11.

If everyone brought back nearly two year old threads because they thought "they still contain useful information" then we'd never be able to read the new threads from people with genuine problems from sifting through all the old stuff. It still seems really random that without anyone needing the info such an old thread is bumped, and you may as well have simply posted a "bump" since your suggestion had already been posted and it would have been clearer that it was an old thread being moved for the sake of being moved.

Stop worrying about the age of the thread.

I'm not trying to stop "experts" with time on their hands, the CIA or MI5 deciphering my file.
It could take a while !!

Be careful of what file you use as a keyfile. The first time I was messing around with Truecrypt, I used an mp3 file.

I forgot that Itunes (and probably other media players) messes about with the ID3 tags in MP3 files all the time - and Truecrypt will only accept the file if it is exactly the same.

Luckily I backed up the key

Don't worry, as soon as I heard about that feature I was already thinking about it having to be something that never really got changed and that I would always keep a copy of. I'll play around testing first and get comfortable with it before I actually start using it for real.

I'm not talking about the strength of the encryption itself but that at a fundamental level winzip is easy to crack otherwise those password recovery tools wouldn't work would they? Even if I'm wrong, where's the advantage in paying for software when there are free better alternatives?

I need a simple tool for 2 other people to regularly transfer data file between themselves.

I only mentioned WinZip as I didn't realise it had this facility.

Hmmm, yeah as mentioned Winzip's encryption isn't great. I seem to remember from reading it can be broken in a matter of hours. I'd consider Winzip primarily a compression app (shareware), although there are just as good free alternatives like 7-Zip and TugZip.

TrueCrypt is excellent. One of the best free apps out there. It can be a little bit more tricky to use though for a typical user.

Old threads are ok to re-surface, although you nothing too old given how quickly technology changes, they may become irrelevant, or outdated.

yes brute forcing takes a while, thats why smart people don't do it and either use dictionary based attacks, hash tables (if you can extract the password hash) or some fundamental flaw in the process (as is the case with winzip)
