Previously, only a contiguous block of uids would be presented to the user when trying to disambiguate a key. This happened because a key may have other fields interspersed among the uids, like UAT. Signed-off-by: James McCoy <vega.james@gmail.com>

" Description: {{{2
|
||
"
|
||
" 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, swapfile, and undofile to increase security.
|
||
"
|
||
" Installation: {{{2
|
||
"
|
||
" 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 out‐
|
||
" put 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.
|
||
"
|
||
" Commands: {{{2
|
||
"
|
||
" :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: {{{2
|
||
"
|
||
" 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
|
||
" unless a "*.asc" file is being edited.
|
||
"
|
||
" 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: {{{2
|
||
"
|
||
" 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.
