Hi!
just a short note: The reason why we have compresion algorithms in
OpenPGP are mainly out of tradition. On a Unix system the use of
specialized tools is the way to go; e.g. gpg for encryption and bzip2
for compressing.
If you want to compress your data with a different algorithm you may

If speed isn't an issue, why would anyone prefer rar over bzip2? Bzip2
compresses much better than rar anyway, although it's slow.

Bzip2 does not compress better than RAR or LZMA, at least with my test corpus.

LZMA seems to be notably[1] faster/better than BZIP2, which has made
it into the standard so I wouldn't immediately rule out its
suitability for OpenPGP.
That said I don't much think it should be included. It could *replace*
BZIP2 but replacing BZIP2 with LZMA would break backwards
compatibility

The RAR compression algorithm proprietary and closed source, so it is
not likely to make it into any standards. RARlabs has refused for
years to allow anyone else to make RAR encoders (although they exist

if you really want a particular algorithm, it's healthier to get the

How well was LZMA known when BZIP2 made it in? Why was BZIP2 included

In fact, BZIP2 was added pretty much for archival purposes:

I wouldn't be against LZMA if it was significantly better than BZIP2.
My understanding of the reason behind compression in OpenPGP is that it

The current version of GnuPG I have supports only three compression
algorithms viz: ZIP, ZLIB and BZIP2
Is there a way to direct GnuPG to use some other algorithm besides
these? for example RAR (http://rarlabs.com/)...
No. GPG supports
