==================

that will only encrypt stdout, leaving stderr (if there is any) 
unencrypted. solve that by running:
 	cron-job-command 2>&1 | gpg --trust-model always -ear somekey

("--trust-always" is deprecated, use "--trust-model always")
(also, as a matter of habit, options before commands (mostly))

your subject line will be visible to anyone who may intercept the 
message... if that's a problem, write a tiny shell script that runs the 
command and pipes the output through gpg-encrypt... run that script from 
cron and then the subject line will just read "Cron 
/path/to/shell/script", which may reveal less useful information to an 
attacker.

 	 is spending the sweat of its laborers, the genius of its
