Croncrypt
=========
Wrapper to sign and encrypt `cron(8)` output and errors with PGP/MIME before
sending them to the `MAILTO` destination.
$ crontab -l
CRONCRYPT_KEYID=0x0A1B2C3D4E5F6G7H
CRONCRYPT_PASSPHRASE=hibbityboo
MAILTO=me@mynet
0 1 * * * croncrypt rsync /home/tom/important-file /home/backups
The main design goal is simplicity; just whack `croncrypt` in front of all your
`crontab(5)` entries, provided they don’t use pipes or `stderr`/`stdout`
redirects, in which case you should consider putting it all into a script file
anyway.
Don’t use your own GPG key for signing! I recommend you create a dedicated key
just for Croncrypt, and sign it locally with `gpg --lsign` so that your
software trusts it locally.
Installation
------------
Put the `croncrypt` binary somewhere in your `crontab`’s `PATH`, and install
the following Perl modules:
* `Carp`
* `IPC::Run3`
* `Mail::GnuPG`
* `MIME::Entity`
On Debian-derived systems, this should do the trick:
# aptitude install perl-base perl-modules libmail-gnupg-perl \
libmime-tools-perl libipc-run3-perl
