Q: Linux Command Line Encryption

[Ali Campbell <fdisclosure () alicampbell org uk>]

Hi there,

Sorry for a question which I'm sure a lot of people on this list will 
consider trivial, but I'm subscribed, so I might as well ask it here.

I need a Linux utility which I can use to encrypt a single gzipped file 
via the command line. Obviously something open source would be 
preferable. I'm not really interested in setting up a whole suite of 
stuff with keyfiles and so on, and I don't need a public/private key 
setup, just something quick and dirty with a single secret key for 
encryption and decryption which is nevertheless reasonably strong.

Thanks in advance.

Ali
