Comment on TrueCrypt

Encryption software SHOULD be OpenSource to make sure no hidden "backdoor" is installed. Some governments have a strict control over encryption software (search for Strong Encryption Export Controls).

This app can encrypt the entire hard disk. Recommended when your adversary (competitor company or even a dictatorship government) might get access to your computer. You can even make a decoy system if you're forced (torture/extortion) to reveal a password (read PLAUSIBLE DENIABILITY in the USER GUIDE).

For simple things like sending (or saving) a encrypted file(s), just create a volume (it's like a folder), choose a size and put the file(s) inside. TrueCrypt is needed to decrypt.

EVERYONE have sensitive files on their computer and It doesn't have to be illegal. Could be your personal pictures, enterprise docs, bank statements among others. That's why you should use this app and if you're serious about protecting your privacy you should read the USER GUIDE (included in this app).
