Yes. Absolutely. There are many excellent tutorial pages on the Web
with links pointing you to the version that's right for you. A really
excellent tutorial for newcomers is here

The latest stable version is PGP is 6.5.8
<ftp://ftp.zedz.net/pub/crypto/pgp/pgp60/> Thankfully there are many
places to download PGP <http://www.cryptography.org/getpgp.htm> .
Desktop Security, Personal Privacy or Freeware versions; all these are
recommended although they are rather bloated (7-11 megs).  Whatever
version you choose, it must be capable of creating and working with
RSA keys since this is what remailer software and nym server software
use for the most part. Check out this excellent Web site for the
lowdown on which versions support RSA keys, Diffie-Hellman keys or
both. <http://rmarq.pair.com/pgp/#chart>

Earlier command line versions of PGP are very popular with remailer
users. PGP 2.6.3i-win32 <ftp://ftp.pgpi.com/pub/pgp/2.x/pc/windows/>
has become something of a standard for Windows users. It is small,
"rock" stable and seems to "play well with others". 'An excellent
companion to any remailer client.
