I am searching for a command line (!) tool which en- and decrypts files and folders
with the well known AES algorithm. I should be able either to pass the password as parameter
resp. the program should ask the user for a password at the command line.

Can someone recommend me such a tool for WinXP ?

Again, it should not (only) be a GUI based encryption utility but a small, ressource friendly
command line based tool.

Here is an excerpt from `eix -sS aes':

app-crypt/aes-crypt
Abstract: Command line program ('aes') to encrypt and decrypt data using the Rijndael algorithm (BSD)
Homepages: http://my.cubic.ch/users/timtas/aes/

app-crypt/aespipe
Abstract: Encrypts data from stdin to stdout (GPL-2)
Homepages: http://loop-aes.sourceforge.net

Those are Unix/Linux programs in their original form, but mostly there
is a Windows version out there, so have a look at their homepages. If
not, you can compile most of these tools with the help of Cygwin [1] or
your native compiler, or with Dev-C++ [2] if you don't have any.

The Rijndael home page has a reference implementation and a list of
links to other implementations:

Overkill in this case, and more effort necessary, as (at least in my
version) CAST5 is the default cipher.

gpg --cipher-algo aes -c filename.ext

gpg -c --cipher-algo aes

YMMV
