# $Log: pgpPgp5.tcl,v $
# Revision 1.8 2005/01/01 20:16:20 welch
# Based on patches from Alexander Zangerl
# lib/pgpGpg.tcl:
# lib/pgpPgp5.tcl:
# fix of an old pgp problem where recipients were duplicated when
# pgp is run in interactive mode
# lib/extrasInit.tcl: a small documentation improvement for the
# pgp(getextcmd) functionality.
# faces(xfaceProg) gains a default (uncompface -X)
# lib/pgpExec.tcl: fix for http://bugs.debian.org/164210: multiple gpg
# subkeys and passphrases. exmh would not ask for the right passphrase.
# lib/addr.tcl: ldap options gain defaults that are compatible with
# debian's openldap config
# lib/mh.tcl: add Msg-Protect and Folder-Protect to the default .mh_profile
# that is generated when setting up new users.
#
# (These changes are inspired by a patch from Alexander, but not the same)
# lib/inc.tcl: use $install(dir,bin) to specify an absolute path to
# the inc.expect script
# lib/seditExtras.tcl: use $install(dir,bin) to specify an absolute path to
# the exmh-async script
# lib/mime.tcl: use $install(dir,bin) to specify an absolute path to
# the ftp.expect script.
# Also changed MimeMakeBoundary to use [clock seconds] instead of
# re-writing the output of [exec date].
#
# Revision 1.5 2001/02/04 15:45:40 iko
# gpg fixes + icon position
#
# Revision 1.4 2001/02/01 23:01:32 iko
# Misc. fixes
#
# Revision 1.1.1.3 2001/02/01 15:02:58 iko
# upstream 2.3.1
#
# Revision 1.7 2001/01/04 02:24:46 bmah
# Add +force to PGP5 flags. This fixes
# a bug where PGP5 couldn't verify clearsigned messages under some
# circumstances. In my testing I was only able to make this happen
# with clearsigned messages and multipart/mime, which produces some
# rather strange output anyways. But this doesn't seem to hurt
# anything.
#
# Submitted-by: Dave Tweten <tweten@nas.nasa.gov>, via the FreeBSD
# Project
#
# Revision 1.6 2000/04/18 18:38:33 valdis
# Fix quote character to use ascii rather than iso8859-ish one
#
# Revision 1.5 1999/09/30 03:51:07 kchrist
# pgp($v,cmd_Beauty) was getting in the way of pgp($v,cmd_User) for
# v=gpg so I had to rearrange things a bit.
#
# Revision 1.4 1999/09/27 23:18:46 kchrist
# More PGP changes. Consolidated passphrase entry to sedit field or
# pgpExec routine. Made the pgp-sedit field aware of pgp(keeppass)
# and pgp(echopass). Moved pgp(keeppass), pgp(echopass) and
# pgp(grabfocus) to PGP General Interface. Fixed a minor bug left
# over from my previous GUI changes. Made pgp-sedit field appear and
# disappear based on its enable preference setting.
#
# Revision 1.3 1999/08/13 00:39:06 bmah
# Fix a number of key/passphrase management problems: pgpsedit now
# manages PGP versions, keys, and passphrases on a per-window
# basis. Decryption now works when no passphrases are cached.
# One timeout parameter controls passphrases for all PGP
# versions. seditpgp UI slightly modified.
#
# Revision 1.2 1999/08/03 04:05:56 bmah
# Merge support for PGP2/PGP5/GPG from multipgp branch.
#
# Revision 1.1.4.1 1999/06/14 20:05:16 gruber
# updated multipgp interface
#
# Revision 1.1 1999/06/14 15:14:55 markus
# added files
#
# Revision 1.4 1998/12/08 15:04:46 markus
# modified cmd_cleanOutput
#
# Revision 1.3 1998/12/06 16:27:22 markus
# Added DecryptExpect and subkey support
#
# Revision 1.2 1998/12/02 20:06:33 markus
