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.

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.

Known Issues:

  In some cases gvim can't decryt 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.
