Emailing a base64 + encrypted message using a key


If you need to send an encrypted message to a friend look no further. You can use the following set of instructions to do this. The encryption is not industrial strength but it certainly will keep snoopers out of the loop. You can do man crypt for more info.

Software Requirements

Freebsd ( may work with others)
(crypt/enigma)
(b64encode/uuencode)

In Ubuntu you can use base64 in the place of b64encode. However at this time I don’t know about any crypt type programs installed by default.

Requirements
=============
Shared password between parties

Sending a message
==================
vi message.txt (type up the message)
cat message.txt | enigma | b64encode message.txt > encoded.txt

email encoded.txt

Getting a message
==================

cat encoded.txt | b64decode -cp | enigma > decoded.txt
