GPG Encryption in Vimtouch

[Gregory Manning]

On windows, I use the gnupg plugin[0] to save and load file.txt.gpg
files seamlessly. I'd like to do something similar on android. (Actually
I'm mostly interested in writing files in vim, encrypting them to myself
for later reading on other devices - I'd be happy with just encryption -
no signing, no decryption).

I've tried installing Gnu privacy guard[1] which gives me a gpg
excutable under /data/data/info.guardianproject.gpg/app_opt/aliases/gpg.
I've set up my .vimrc with settings that vim-gnupg expects.

When I run this from the adb shell I get sensible looking output[Sane
GPG output].

VimTouch seems to pick up the plugin, but when I open a file
test.txt.gpg, I get errors.

I enabled the debug logging in vim-gnupg. The contents are below[Log file].

I think that the system call here[2] is not working - it's giving return
code 122 and no output.

Does anyone with more idea about vimtouch have any idea what to try next?

Thanks,

Greg.
