Subject: Newbie:steps to send pgp encry. mail

I know nothing about sending encrypted email (not to mention PGP 
encrypted mail). So can someone outline the steps I need to take to
send PGP encrypted email. Maybe sone specific questions will help too:
1. What other software do I need to run besides the elm and pine we
run on the unix machine
2. What is the PGP public key ? How and where to put in with the mail ?
3. What versions of elm or pine must I use ?

I am trying to answer this on page
	http://www.math.fu-berlin.de/~guckes/elm/elm.pgp.html

It's still just a draft, so I welcome all hints for more info.
I have stored some URLs about PGP somewhere which I will add RSN.

Well, "pgp" for one thing.
For now, please take a look at alt.security.pgp and the FAQs therein.

>2. What is the PGP public key ? How and where to put in with the mail ?

PGP is a "public key crypto system", meaning that you can publish your
"public key" (a data set) for others to encrypt mail for you which you will
be able to read (decrypt) with your "secret key".

>3. What versions of elm or pine must I use ?  

If you just use the PGP scripts (morepgp, mailpgp) then any version of ELM
will do.  However, you need "perl" as they were written in perl.

There is a set of patches for ELM2.4PL24 written by Michael Elkins which
add PGP support to ELM.  More info on that from the above mentiones page.
There are links to Michael's www pages, too.

First recommendation, buy the book _PGP: Pretty Good Privacy_ by Simson
Garfinkel, published by O'Reilly.  I would find it hard to believe
that it is not available in Hong Kong, at least at some of the bigger
bookstores or at the college book store.  Phil Zimmerman also has a
book out published by MIT Press, but I can't remember the title.  The
Garfinkel book is pretty much the standard text on PGP.  

>1. What other software do I need to run besides the elm and pine we
Obviously, PGP, and an editor.  There is a version of elm that
combines an interface to PGP with it.  When you are ready to send a
message, in addition to the usual choices of send, edit, and forget
it, you are also given a choice pgp.  If you choose pgp, you can
encrypt, sign, or both.  The encrypt has a problem in that if the
address does not exactly match the key owner, it can't find the key.
For example, my key is owned by [email-masked].  If you had this key in
your public ring, and tried to encrypt a reply to this message, the
mailer wouldn't find it, since our mailer attaches the machine name to
the from line, and my address is [email-masked].  But for the
most part the elm/PGP combo is handy.  Also useful if you use emacs is
mailcrypt.  With mailcrypt, you can encrypt your files (messages) from within
emacs. But all you really need is a mail program, editor, and pgp.

>2.  What is the PGP public key ?  How and where to put in with the mail ?
The public key is the key is the key that you let anyone have to send you
messages.  There is no attempt to keep it secret.  Here is my key:
- -----BEGIN PGP PUBLIC KEY BLOCK-----
Version: 2.6.2

mQBtAy9t1tgAAAEDALtPwQ7n5gHHiZkpPzUPwXiYz2LLpvirqvFC8iiiE3xG6Wk6
Dd6wBqPNYwYmz8Cy1AAu1UMMwoLSPKsxiugnGmQmUHSYGpikkqp9uS1l4tJUXPXv
8Q6ga+mLT9tWsA2pWQAFEbQcQmlsbCBSb2JlcnRzIDxiaWxsckB0c2MuY29tPg==
=Glx4
- -----END PGP PUBLIC KEY BLOCK-----

You can use the above key to verify my signature to this message,
check my fingerprint, or send me an encrypted message.  The issue of
whether I am really the Bill Roberts who works at TSC, or an imposter
stealing his mail is another issue entirely.  (I am, I swear it).

>3. What versions of elm or pine must I use ?  
Any version that works for you.  I would recommend that when you
encrypt something, though, you use "ASCII armor" and set text mode.
Some mailers (maybe one along the path of your message) don't like
non-ASCII characters in messages.  text mode provides protection for
different text files.

Best bet, get the book and read it.  Then try using PGP to send and
receive both plain text, signed messages (like this one) or encrypted
messages.  

Hope this helps.

(n for next message, return for signatures)
