PGP or GPG are the obvious solutions.  With both, you can use
"conventional encryption" to use a single shared password that your small
group of select users would know.  The alternative would be to encrypt it
to each of their private keys.

Sounds like you definately could use batch encryption here.  Something you
could do with a simple shell script or batch mode.

Easily done with pgp or gpg.  I would highly recommend acquiring and using
them since they're such a usefull tool all around.
