Is there a way to encrypt a file in Android 4.1?
In Linix vim there is an option (vim -x) to do this, but it does not seem to be present in VimTouch.
I'd like if possible to share an encrypted file between PC and phone.
Any advice or suggestions gratefully received.

That depends on exactly what you mean by encrypted, but if you just want protection, either use PGP on both devices, or zip the file with password protection.
