GnuPG (gpg) is certainly one possibility.
The right answer may depend on why you want
the file encrypted, and what you intend to do
with it.

Depending of the file, if it's just a text file, you can use the :X commmand in vi.

You can also use the zip -e command:

zip -e test.zip testfile
Enter password:
Verify password:
adding: prueba (stored 0%)

All the above are valid.

Also you can use the openssl one

Encrypt file.txt to file.out using 256-bit AES
$ openssl enc -aes-256-cbc -salt -in file.txt -out file.out
Type password
verfy passwd

Decrypt encrypted file file.out
$ openssl enc -d -aes-256-cbc -in file.out
Type passwd to decrypt
