facility for sending/reading encrypted mail

Since there's been a lot of discussion on the net about the
privacy of mail, I decided to post a little hack I did about 3
years ago for sending encrypted mail using des(1). I've updated
it a little - it not does compression/decompression on your
message, so the mailer doesn't have to work quite so hard...:)
This thing uses uudecode/uuencode, compress/zcat, and des (if you
don't have a version of des for your system, there's one floating
around on uunet in comp.sources.unix, I think. I'm using Phil
Karn's excellent implementation posted to the net several years back.)
Sophisticated users/programmers will wonder why I didn't do
this in a shell script. I wonder that, myself...:) Mainly
so that casual users (whatever that means) won't poke around in
the guts and possibly work around it. It could easily have
been done in a shell script.
Besides, I hate shell scripts! :)
Have fun with it -- I've gotten a lot of mileage out of it. It's
particularly useful for talking about your boss/sysadmin behind
his/her/its back. :)
The code is pretty self-explanatory -- one thing you might want
to change is MAILCMD in sendmail.c - it's set for "mailx" at
the moment.
If there are potential employers/job shops/contractors/whatever
out there, don't look at this as an example of programming
style. Just look at as just another one of those pesky tools
written by Mr. ToolCrafter himself. :)

X.TH READSECRET 1L "June 7, 1991"
X.SH NAME
Xreadsecret \- read a secret mail message
X.SH SYNOPSIS
Xreadsecret
X.I file
X.SH DESCRIPTION
X.I readsecret
Xreads a secret mail message sent by
X.I secretmail(l).
X.PP
XTo read a secret mail message, the message itself must be saved in a
Xunique file. Then
X.I readsecret
Xis called to uudecode, uncompress and decrypt the secret mail message.
XFinally, the
Xfile may be deleted. For example, if a secret mail message has been saved
Xin a file called
X.I oneshot,
Xthe command
X.PP
Xreadsecret oneshot
X.PP
Xwould display the secret message (after asking for a password). After
Xthe message has been read, the file
X.I oneshot
Xmay be deleted.
X.SH FILES
Xsecret.let work file
X.SH CREDITS
XThis utility was written by Edwin R. Carp.
X.SH BUGS
XThe non-EDITOR interface to mail is not the best in the world.
X.PP
XThere is no way to indicate to the user that an incorrect password
Xhas been entered.
X.PP
XThe file is read in as "./secret.let". This can be disruptive to other
Xfiles in the current directory called "secret.let".
X.PP
XThe current version of
X.I readsecret(1)
Xand
X.I secretmail(1)
Xis not compatible with previous versions.

X.SH NAME
Xsecretmail \- send mail via secure communications channel
X.SH SYNOPSIS
Xsecretmail [
X.I -puyr
X] [
X.I -s subject
X]
X.I user(s)
X.SH DESCRIPTION
X.I secretmail
Ximplements a secure communications conduit for
X.I mail(1)
Xusing the standard DES algorithm. It is primarily useful
Xfor sending confidential information that need not be readable by
Xa priviliged user. Only the user for which the mail is intended
X(has the password) may read the mail.
X.PP
X.I secretmail
Xprompts for the subject of the message, then runs
Xwhatever editor is set up in the environment variable EDITOR.
XIf EDITOR is not set, then
X.I secretmail
Xuses a mail-like interface.
XAfter ending input with a control-D, the screen is scrolled up 25 lines
Xand the user is prompted for a password (or key). The mail is then
Xcompressed, encrypted, uuencoded, and sent.
X.SH OPTIONS
X.IP r
XThis option is used to send routine mail, and is the default.
X.IP u
XThis option is used to send urgent mail to be read as soon as possible.
X.IP p
XThis options is used to send mail of the highest priority (to be read
Ximmediately).
X.IP y
XThis options is used to send mail that is intended to be read by the
Xrecepient only.
X.SH BUGS
XThe file is sent out as a uuencoded file and decrypted as "./secret.let".
XThis can be disruptive to any files called "secret.let" in the current
Xdirectory.
X.PP
XThe current version of
X.I readsecret(1)
Xand
X.I secretmail(1)
Xis not compatible with previous versions.
