I added this to my .profile alias encrypt="openssl aes-256-cbc -a -salt" alias decrypt="openssl aes-256-cbc -d -a -salt" Very nice! I added this to my .profile

alias encrypt=”openssl aes-256-cbc -a -salt”
alias decrypt=”openssl aes-256-cbc -d -a -salt”

Add the following to your .vimrc file…

” Edit encrypted using openssl aes-256-cbc
augroup enc
autocmd!
autocmd BufReadPre,FileReadPre *.enc set bin
autocmd BufReadPre,FileReadPre *.enc set noswapfile
autocmd BufReadPost,FileReadPost *.enc set shell=sh
autocmd BufReadPost,FileReadPost *.enc set shellredir=>
autocmd BufReadPost,FileReadPost *.enc ‘[,']!openssl aes-256-cbc -d -a
autocmd BufReadPost,FileReadPost *.enc exe “doau BufReadPost “.expand(“%:r”)
autocmd BufReadPost,FileReadPost *.enc set nobin
autocmd BufReadPost,FileReadPost *.enc redraw!
autocmd BufWritePre,FileWritePre *.enc mark z
autocmd BufWritePre,FileWritePre *.enc set bin

autocmd BufWritePost,FileWritePost *.enc undo
autocmd BufWritePost,FileWritePost *.enc set nobin
autocmd BufWritePost,FileWritePost *.enc ‘z
augroup END

To create a new file just start vim without a file name and then ‘write’ it to one ending in ‘.enc’ for example
:w secret_stuff.enc

To look at or modify the file just run vim secret_stuff.enc

WARNING: when saving make sure the file gets written correctly by looking at the output before quitting.
