Recipe 8.2 Encrypted Mail with vim

8.2.1 Problem

You want to compose an encrypted mail
message, and your mail editor is
vim.

8.2.2 Solution

~/.vimrc:
map ^E :1,$!gpg --armor --encrypt 2>/dev/null^M^L
map ^G :1,$!gpg --armor --encrypt --sign 2>/dev/null^M^L
map ^Y :1,$!gpg --clearsign 2>/dev/null^M^L

The ^X symbols are actual control characters inserted into the file, not a caret followed by a letter. In vim, this is accomplished by pressing ctrl-V followed by the desired key, for example, ctrl-V ctrl-E to insert a ctrl-E.

8.2.3 Discussion

These macros filter the entire edit buffer (1,$) through
gpg. The first macro merely encrypts the buffer,
the second encrypts and signs, and the third only signs.
You'll be prompted for your passphrase for any
signing.
