I need to encrypt a file on a Windows 7 machine, and then decrypt it on an Ubuntu machine. What is the simplest way of doing this, preferably with tools that are likely to already be installed on the two machines. I have cygwin on the Windows machine if needed.

OpenPGP using the GnuPG tools will likely be easiest. (GnuPG for Windows comes in both native and Cygwin forms.)
To encrypt with a password:
gpg --symmetric myfile.txt
To decrypt:
gpg --decrypt myfile.txt.gpg

1The --symmetric option by default caches your password locally and you may want to clear it with gpg-connect-agent reloadagent /bye – JosiahYoder-deactive except.. – 2018-08-10T21:41:13.113

I prefer and think that is more easy to do it using one zip archiever with pasword like winrar ow 7zip on windows, copy the file and decompress it in linux.

I know its end of life, but I've yet to see anything that effectively replaces truecrypt. if your adversary is not a nation-state or large company engaged in industrial espionage, truecrypt 7.1a is probably still sufficient to your needs. – Frank Thomas – 2014-07-11T18:36:52.547

@techie007 that's what I ended up doing – PurpleVermont – 2014-07-11T20:33:54.127
