The code was written by a colony of drunk monkeys, in an era before anyone understood the basics of modern cryptography; I'm really not sure which is worse between gnupg and OpenSSL. Of course, GPG is the standard for encrypted email, just like SSL/TLS is the standard for web sites, so you may have no choice...

Do you have any recommendations for high-level alternative for GPG, i.e. something that can secure data easily at rest. Is there something that wraps e.g. NaCL with file IO in a nice commandline utility?

At work we are occasionally using 7zips encryption ability, but somehow I don't really have high confidence in it. But at least the UI is simple enough.

The scrypt encryption utility (http://www.tarsnap.com/scrypt.html) is pretty simple, but it does what you are asking.

That's symmetric encryption using a passphrase though. Since he mentioned GPG I assume he's looking for public-key encryption.
