This info can also be found on the Internet, but I thought I compile it here too.
You want to save something (say passwords) in a file and protect the file with a master password (say with your PGP/GPG key). This can be cumbersome unless you have vim.
The following examples will handle
*.gpg files differently,
decrypt the file when opening it and encrypt the file when writing it.
Also the use of a swap file is disabled.
The following config will make
vim behave like described above manner:
augroup gpg au! au BufReadPre,FileReadPre *.gpg set viminfo= au BufReadPre,FileReadPre *.gpg set noswapfile au BufReadPost *.gpg :%!gpg -q -d au BufReadPost *.gpg | redraw! au BufWritePre *.gpg :%!gpg --default-recipient-self -q -e -a au BufWritePost *.gpg u au VimLeave *.gpg :!clear augroup END
Just add it to your
~/.vimrc and your are set.
I’ve found this config somewhere on the Internet (lost the reference), so it’s not my idea.
