Add Password Protection to a file your editing in vim.

vim -x <FILENAME>
While I love gpg and truecrypt there's some times when you just want to edit a file and not worry about keys or having to deal needing extra software on hand. Thus, you can use vim's encrypted file format. For more info on vim's encrypted files visit: http://www.vim.org/htmldoc/editing.html#encryption

What Others Think

Shouldn't that be 'vim -x '? 'vim -e' puts you into ex mode...

from http://www.vim.org/htmldoc/editing.html#encryption 'The normal way to work with encryption, is to use the ":X" command, which will ask you to enter a key.' Interesting and thanks, good to learn something. vote++;

@mayersjl thanks, I'll fix that up for everyone @mpb Glad I could help.

Note that the encryption vim uses is really weak, so it is not really an alternative to gpg and the likes (this is also noted in the documentation linked). That said, it is useful for quick and dirty obfuscation :)

Online docs moved, now located at http://vimdoc.sourceforge.net/htmldoc/editing.html#encryption As noted in those docs, vim 7.3+ supports the blowfish cypher, which will give you stronger encryption (and makes the file unusable to older versions of vim). You can launch this directly from the command line with: vim -x +"set cm=blowfish" <FILENAME>
