RFS: aespipe
Max Vozeler
I'm looking for a sponsor for aespipe.
Package: aespipe
Version: 2.2b-2
Upstream: Jari Ruusu <jari...@users.sourceforge.net>
URL: http://loop-aes.sourceforge.net/aespipe
License: GPL
Description: AES-encryption tool for tar/cpio and loop-aes imagesa
aespipe is an encryption tool that reads from standard input and
writes to standard output. It uses the AES (Rijndael) cipher.
.
It can be used as an encryption filter, to create and restore
encrypted tar/cpio backup archives and to read/write and convert
loop-AES compatible encrypted images.
.
aespipe can be used for non-destructive in-place encryption
of existing disk partitions for use with the loop-AES encrypted
loopback kernel module.
The package is linda and lintian clean. You can find it here
deb-src http://hinterhof.net/~max/debian ./
Cheers
Max

i don't understand why you can't use gpg for these things.

Likely because gpg wraps data in OpenPGP packets, which is not much
good when you want to just produce a raw encrypted stream, like for a
loopback partition.
It does seem as though "openssl enc -aes-128-cbc" is pretty close to
what he wants here.

You can for many tasks use gpg instead. aespipe is most useful in
combination with loop-AES as it understands the on-disk format of
those encrypted images and partitions.
Most people use aespipe to access encrypted disk images when there
is no kernel support available, or eg. to write encrypted CD images
that can be transparently mounted.

Indeed.

Yes, that's pretty close for general encryption purposes. aespipe also
understands the combination of hashing algorithms that loop-AES uses
for different key sizes and supports its multi-key IV initialisation
mode. These settings are difficult if not impossible to get right
"by hand"

I can see the point of having this utility. But can't it be merged
into the 'loop-aes-utils' package? Why would users want one but not
the other?

Some users may want to use aespipe without loop-AES due to its support
for seeding and iteration count. Someone who just wants to access an
encrypted backup from another machine also doesn't need the patched mount
utils from loop-aes-utls.

ah ok, now in understand why it is usefull.
thank you.
