description

This script implements transparent editing of gpg encrypted files. The filename must have a ".gpg", ".pgp" or ".asc" suffix. When opening such a file the content is decrypted, when opening a new file the script will ask for the recipients of the encrypted file. The file content will be encrypted to all recipients before it is written. The script turns off viminfo and swapfile to increase security. This is a continuation of the work initially done by Markus Braun in vimscript #661.  Development takes place at https://github.com/jamessan/vim-gnupg. Commands:   :GPGEditRecipients     Opens a scratch buffer to change the list of recipients. Recipients that     are unknown (not in your public key) are highlighted and have     a prepended "!". Closing the buffer makes the changes permanent.   :GPGViewRecipients     Prints the list of recipients.   :GPGEditOptions     Opens a scratch buffer to change the options for encryption (symmetric,     asymmetric, signing). Closing the buffer makes the changes permanent.     WARNING: There is no check of the entered options, so you need to know     what you are doing.   :GPGViewOptions     Prints the list of options. Variables:   g:GPGExecutable     If set used as gpg executable, otherwise the system chooses what is run     when "gpg" is called. Defaults to "gpg".   g:GPGUseAgent     If set to 0 a possible available gpg-agent won't be used. Defaults to 1.   g:GPGPreferSymmetric     If set to 1 symmetric encryption is preferred for new files. Defaults to 0.   g:GPGPreferArmor     If set to 1 armored data is preferred for new files. Defaults to 0.   g:GPGPreferSign     If set to 1 signed data is preferred for new files. Defaults to 0.   g:GPGDefaultRecipients     If set, these recipients are used as defaults when no other recipient is     defined. This variable is a Vim list. Default is unset.   g:GPGUsePipes     If set to 1, use pipes instead of temporary files when interacting with     gnupg.  When set to 1, this can cause terminal-based gpg agents to not     display correctly when prompting for passwords.  Defaults to 0.   g:GPGHomedir     If set, specifies the directory that will be used for GPG's homedir.  This     corresponds to gpg's --homedir option.  This variable is a Vim string. Known Issues:   In some cases gvim can't decrypt files   This is caused by the fact that a running gvim has no TTY and thus gpg is   not able to ask for the passphrase by itself. This is a problem for Windows   and Linux versions of gvim and could not be solved unless a "terminal   emulation" is implemented for gvim. To circumvent this you have to use any   combination of gpg-agent and a graphical pinentry program:     - gpg-agent only:         you need to provide the passphrase for the needed key to gpg-agent         in a terminal before you open files with gvim which require this key.     - pinentry only:         you will get a popup window every time you open a file that needs to         be decrypted.     - gpgagent and pinentry:         you will get a popup window the first time you open a file that         needs to be decrypted.

install details

Copy the gnupg.vim file to the $HOME/.vim/plugin directory. Refer to ':help add-plugin', ':help add-global-plugin' and ':help runtimepath' for more details about Vim plugins. From "man 1 gpg-agent": ... You should always add the following lines to your .bashrc or whatever initialization file is used for all shell invocations:      GPG_TTY=`tty`      export GPG_TTY It is important that this environment variable always reflects the output of the tty command. For W32 systems this option is not required. ... Most distributions provide software to ease handling of gpg and gpg-agent. Examples are keychain or seahorse.

package	script version	date	Vim version	user	release notes
gnupg.vim	2.5	2012-06-01	7.2	James McCoy	* Ignore keys that aren't usable for encryption instead of simply ones that are expired
gnupg.vim	2.4	2012-05-31	7.2	James McCoy	* Improvements when an encrypted file is being '":read" into another buffer. ** Don't wipeout the current buffer if decryption fails. ** Use the current buffer's settings for 'swapfile' and 'undofile' instead of disabling them. * Make 'u' a no-op immediately after loading the file, just like with normal files. * Avoid prompting for disambiguation of keys once the user has selected which one to use. * Ignore expired keys when trying to find a matching key for an id entered in ":GPGEditRecipients"
gnupg.vim	2.3	2011-11-23	7.2	James McCoy	* Resolve the filename when saving to follow symlinks. * Add support for specifying an alternate --homedir, using the g:GPGHomedir variable
gnupg.vim	2.2	2011-08-13	7.0	James McCoy	Correctly handle the different keyid-format options
gnupg.vim	2.1	2011-08-10	7.2	James McCoy	Add g:GPGUsePipes variable to avoid saving unencrypted data to tempfiles (in a private directory)
