[REQ] loop-aes

Hi,

might be a bit difficult, because the kernel's loop module must be patched and the util-linux package must be patched for loop-aes. However, I really need it - perhaps someone could help me building this package.

Is this what you are asking for?

No. aespipe encrypts data from stdin to stdout - that's also nice, but it can't be used to mount an encrypted block device or file.

Re: [REQ] loop-aes

Well, I've got a workaround solution: I wrote a script in the good old days of Gentoo. To get it working under arch I had to remove the replacement of the man pages since the paths don't exist. Here it is:

Use with caution! Though it is working without problems for me, it may cause damage to your system, because it's not well tested and it has nothing to do with AUR or pacman - it's just the quick'n'dirty way!
