One could use something like this:
# Create empty file
dd if=/dev/zero of=testfile bs=1024 count=1024

# Compress it with zlib Routine (-z 9) and encrypt it with a password
# from $PASSWORDFILE
cat testfile | gpg --passphrase-fd 3 -z 9 --no-tty -c - 3<$PASSWORDFILE
>testfile.gpg

# Decompress and decrypt with a password from $PASSWORDFILE
cat testfile.gpg | gpg --output - --passphrase-fd 3 --no-tty --decrypt
- - 3<$PASSWORDFILE > test

This works and gpg can handle STD(IN|OUT). But how do I implement this
into amanda? And is there a possibility that I have to enter the
password when I want to recover some files?


Thanks in advance,
Nicki
