== Edit OpenSSL encrypted files and turn Vim into a Password Safe! ==
|
||||
|
||||
This plugin enables reading and writing of files encrypted using OpenSSL.
|
||||
The file must have the extension of one of the ciphers used by OpenSSL. For
|
||||
example:
|
||||
|
||||
.des3 .aes .bf .bfa .idea .cast .rc2 .rc4 .rc5
|
||||
|
||||
This will turn off the swap file and .viminfo log. The `openssl` command
|
||||
line tool must be in the path.
|
||||
|
||||
== Install ==
|
||||
|
||||
Put this in your plugin directory and Vim will automatically load it:
|
||||
|
||||
~/.vim/plugin/openssl.vim
|
||||
|
||||
You can start by editing an empty unencrypted file. Give it one of the
|
||||
extensions above. When you write the file you will be asked to give it a new
|
||||
password.
|
||||
|
||||
== Simple Vim Password Safe ==
|
||||
|
||||
If you edit any file named '.auth.bfa' (that's the full name, not just the
|
||||
extension) then this plugin will add folding features and an automatic quit
|
||||
timeout.
|
||||
|
||||
Vim will quit automatically after 5 minutes of no typing activity (unless
|
||||
the file has been changed).
|
||||
|
||||
This plugin will fold on wiki-style headlines in the following format:
|
||||
|
||||
== This is a headline ==
|
||||
|
||||
Any notes under the headline will be inside the fold until the next headline
|
||||
is reached. The SPACE key will toggle a fold open and closed. The q key will
|
||||
quit Vim. Create the following example file named ~/.auth.des3:
|
||||
|
||||
== Colo server ==
|
||||
|
||||
username: maryjane password: esydpm
|
||||
|
||||
== Office server ==
|
||||
|
||||
username: peter password: 4m4z1ng
|
||||
|
||||
Then create this bash alias:
|
||||
|
||||
alias auth='view ~/.auth.des3'
|
||||
|
||||
Now you can view your password safe by typing 'auth'. When Vim starts all
|
||||
the password information will be hidden under the headlines. To view the
|
||||
password information put the cursor on the headline and press SPACE.
|
||||
|
||||
Thanks to Tom Purl for the des3 tip.

"
|

" .auth.bfa --> .auth.bak.bfa
