Nice tip.

For a bit more convenience (so you don't have to edit or move the text to a new line):

: ! echo <cWORD> | base64 | tr -d '\n' | pbcopy

:help <cword> and :help <cWORD> for more information

demo 1

For even more convenience, this can be converted into a reusable function:

function! B64ify() abort
  silent ! clear
  silent ! echo <cWORD> | base64 | tr -d '\n' | pbcopy
  execute "normal! ciW\<ESC>\"*p"
  redraw!
endfunction

Now, you can call it with :call B64ify()

demo 2

Lastly, you can map this function to a command and/or keybinding for maximum convenience:

command! B64ify :call B64ify()
nnoremap <silent> <Leader>B :B64ify<CR>

This can also be reversed very easily by copying the function and replacing base64 with base64 -d.

Here is a final demo:

demo 3

The final config:

function! B64ify() abort
  silent ! clear
  silent ! echo <cWORD> | base64 | tr -d '\n' | pbcopy
  execute "normal! ciW\<ESC>\"*p"
  redraw!
endfunction
command! B64ify :call B64ify()
nnoremap <silent><Leader>B :B64ify<CR>

function! B64decodify() abort
  silent ! clear
  silent ! echo <cWORD> | base64 -d | tr -d '\n' | pbcopy
  execute "normal! ciW\<ESC>\"*p"
  redraw!
endfunction
command! B64decodify :call B64decodify()
nnoremap <silent><Leader>b :B64decodify<CR>

Nice tip - I love the <cWORD> approach to a lot of things. One limitation is <cWORD> uses vi's word selection. If my secret is a multiline certificate, the contents of a yaml file, or has special characters this won't work.

That's true.

If you want to visually select the text to pass to an external program, by default vim passes whole lines (e.g. :'<,'> ! base64) , but vis.vim plugin might help (e.g. :'<,'>B ! base64).
