Ever wanted to edit some files you've encrypted with mcrypt(1), but didn't want nasty unencrypted files lying around? With Vim and a little autocommands magic you can:
" ###### LOADING ###### autocmd BufReadPre,FileReadPre *.nc set bin "binary mode autocmd BufReadPre,FileReadPre *.nc set noshelltemp "force the use of pipes autocmd BufReadPre,FileReadPre *.nc set noswapfile "disable swapfiles "decrypt the file autocmd BufReadPost,FileReadPost *.nc '[,']!mcrypt -d autocmd BufReadPost,FileReadPost *.nc set nobin "turn off binary mode
" ###### SAVING ###### autocmd BufWritePre,FileWritePre *.nc set bin "binary mode "encrypt the data autocmd BufWritePre,FileWritePre *.nc '[,']!mcrypt "decrypt the buffer again autocmd BufWritePost,FileWritePost *.nc '[,']!mcrypt -d autocmd BufWritePost,FileWritePost *.nc set nobin "turn off binary "trigger a screen redraw cuz things are fucked up autocmd BufWritePost,FileWritePost *.nc normal ^L
NOTE: this may not be entirely secure, this is just something I pulled out of my ass while offline and browsing the vim documentation. It seems to work as desired, but you never know.
TODO: make the save part suck less (currently you need to type the passphrase *3* times, and vim gets all screwed up (hence the ctrl-l as the last step which forces a redraw). I'm not sure exactly how to do this though.
