The answer is in the "Elm Reference Guide". There are two keywords used
for this feature: "[encode]" and "[clear]". You simply bracket the text
to be encrypted with these keywords. For example, the following message
would have some encrypted text:
Hi,
This text isn't encrypted.
[encode]
This text is encrypted.
[clear]
This text isn't encrypted.
Elm will prompt for the encryption key when you confirm that you want to
mail the message. The person receiving the message will be prompted for
the key when they attempt to read it so you must have already agreed
upon the key.
Good luck.

For encrypted (sort of) mail, consult manual page on:
xsend, xget, enroll (1) - secret mail

In the body of the script: enter '[encode]' as the first 8 characters of a line and then continue entering your text in the following lines. (the ' is not to be typed). Having finished your secret part of the message, enter '[clear]' and continue with the message. After you verify the send option, you should be asked for an encryption key and confirmation. When reading mail containing encrypted material, elm prompts you for the encryption key. I tried it and it worked well. Indra K.

The "elm" encrytpion algorithm is not the same as some standard Unix tool, so you need to decrypt via "elm" also. Just don't suddenly delete the "elm" executables and leave yourself with a big pot of encrypted mail. Other than that, it works like a champ. Bill Carpenter (AT&T gateways)!ho5cad!wjc
