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.

Whats wrong with openssl ?

openssl des3 -in test.txt -out test.txt.enc


openssl aes-256-cbc -in test.txt -out test.txt.enc

This is only as strong as your passphrase. Using something like GPG has other advantages since the private key can be kept in a separate location from the encrypted file.
