Hello.
I am searching for a tool to encrypt just a few files and not the whole harddrive like truecrypt does. For I am neither a security expert nor too much into cryptography it should be simple to use. When I installed the tool and encrypted some files, are there any precautions left to take care of, e.g. protecting .conf-files? Is there any protection against forcing me to reveal my passwords and therefore my encrypted content?

you can always use smal file (i.e. 30MB) and encrypt it with truecrypt then mount it during login

I suggest either:
Truecrypt
EncFS
If you want to go really light, and have just a couple of files, you can get by with this:
openssl aes-256-cbc -in plaintextfile -out ciphertextfile (to encrypt)
openssl aes-256-cbc -d -in ciphertextfile -out plaintextfile (to decrypt)

A few files ?
You can use gpg with a symmetric encryption.
The day Microsoft makes a product that doesn't suck, is the day they make a vacuum cleaner.

But if they tell you that I've lost my mind, maybe it's not gone just a little hard to find...

GPG will get the job done, but maybe not ideal unless you also use it for email (its most common use). I use mcrypt when I only need it for a few files.

Try Elettra, it provides plausible deniability http://www.winstonsmith.info/julia/elettra/
You need to install an RTFM interface.

GPG all the way...
Arch Linux + sway
Debian Testing + GNOME/sway
NetBSD 64-bit + Xfce

Thank you very much for your suggestions. I'll read and try each of them.

@hauntergeist,
You couldn't get much smaller or simpler than the command bcrypt, available from the AUR at http://aur.archlinux.org/packages.php?ID=12156.
It's cross-platform too, which is useful for me since I need to use some common files between Linux and Windows.
See http://bcrypt.sourceforge.net/
(If you need to encrypt folders or quite a few files, TrueCrypt as suggested earlier is hard to beat.)

eCryptFS is also an idea; it's a fake-ish filesystem that gets mounted to a folder. Anything that is stored inside will be encrypted and stored on the mother filesystem. Unmount eCryptFS and everything inside looks like garbage I believe. When kernel 2.6.29 comes out, it will be able to encrypt filenames too.
Be sure not to do a lot of serious encryption without encrypting things like swap, /tmp/, /var/tmp/, etc. A few files should be fine though.
