attached is a patch and ChangeLog for a substantial new version of
allout.el, emacs' alternative (and much more extensive) outliner.  i
think it's ready to revise the distributed version.

this version adds topic encryption, using GPG.  it also includes
several fixes and enhancements, described in the ChangeLog entry

below is the synopsis of just the encryption features, from the ChangeLog entry.

	  - new subsystem supporting easy gpg topic encryption/decryption.

	    salient features:

	    - both public- and symmetric-key modes are supported.
	    - encryption being on a per-topic basis means you can
	      intersperse encrypted and clear-text data in a single file
	      to your heart's content.
	    - user-provided symmetric-key hints, with consistency
	      verification to help user avoid confusion
	    - time-limited key reuse, a la (and using) mailcrypt's
	      mc-passwd-timeout
	    - write-file-hook and auto-save-hook activities to support auto
	      encryption of pending topics on save; provision to skip
	      currently-edited topic to avoid editing disturbance

	    topic encryption functionality depends on both mailcrypt and
	    crypt++ packages.  (non-encryption allout functionality is not
	    disrupted if either mailcrypt or crypt++ are absent.)

	    `allout-toggle-current-subtree-encryption' is the central
	    routine.

	    there are a five new encryption customization variables:

	    - allout-topic-encryption-bullet
	    - allout-default-encryption-scheme
	    - allout-key-verifier-handling
	    - allout-key-hint-handling
	    - allout-encrypt-unencrypted-on-saves

	    topic encryption is included in mouse menu

	    docstring for `allout-toggle-current-subtree-encryption'
	    and customization variables provide detailed description.

+
+The idea is to prevent file-system exposure of any un-encrypted stuff, and
+mostly covers both deliberate file writes and auto-saves.
+
+ - Yes: encrypt all topics pending encryption, even if it's the one
+        currently being edited.  \(In that case, the currently edited topic
+        will be automatically decrypted before any user interaction, so they
+        can continue editing but the copy on the file system will be
+        encrypted.)
+        Auto-saves will use the \"All except current topic\" mode if this
+        one is selected, to avoid practical difficulties - see below.
+ - All except current topic: skip the topic currently being edited, even if
+       it's pending encryption.  This may expose the current topic on the
+       file sytem, but avoids the nuisance of prompts for the encryption
+       key in the middle of editing for, eg, autosaves.
+       This mode is used for auto-saves for both this option and \"Yes\".
+ - No: leave it to the user to encrypt any unencrypted topics.
+
+For practical reasons, auto-saves always use the 'except-current policy
+when auto-encryption is enabled.  \(Otherwise, spurious key prompts and
+unavoidable timing collisions are too disruptive.)  If security for a file
+requires that even the current topic is never auto-saved in the clear,
+disable auto-saves for that file."

+  "Encrypt clear text or decrypt encoded contents of a topic.
+
+Contents includes body and subtopics.
+
+Currently only GnuPG encryption is supported.
+
+\**NOTE WELL** that the encrypted text must be ascii-armored.  For gnupg
+encryption, include the option ``armor'' in your ~/.gnupg/gpg.conf file.
+
+Both symmetric-key and key-pair encryption is implemented.  Symmetric is
+the default, use a single \(x4) universal argument for keypair mode.
+
+Encrypted topic's bullet is set to a `~' to signal that the contents of the
+topic \(body and subtopics, but not heading) is pending encryption or
+encrypted.  An `*' asterisk immediately after the bullet signals that the
+body is encrypted, its absence means it's meant to be encrypted but is not
+- it's \"disclosed\".  When a file with disclosed topics is saved, the user
+prompted for an ok to \(symmetric-key) encrypt the disclosed topics.  NOTE
+WELL that you must explicitly \(re)encrypt key-pair encrypted topics if you
+want them to continue to be in key-pair mode.
+
+Level-1 topics, with prefix consisting solely of an `*' asterisk, cannot be
+encrypted.  If you want to encrypt the contents of a top-level topic, use
+\\[allout-shift-in] to increase its depth.
+
+Failed transformation does not change the an entry being encrypted -
+instead, the key is re-solicited and the transformation is retried.
+\\[keyboard-quit] to abort.
+
+Decryption does symmetric or key-pair key mode depending on how the text
+was encrypted.  The encryption key is solicited if not currently available
+from the key cache from a recent prior encryption action.
+
+Optional FETCH-KEY universal argument is used for two purposes - to provoke
+key-pair instead of symmetric encryption, or to provoke clearing of the key
+cache so keys are freshly fetched.
+
+ - Without any universal arguments, then the appropriate key for the is
+   obtained from the cache, if available, else from the user.
+
+ - If FETCH-KEY is the result of one universal argument - ie, equal to 4 -
+   then key-pair encryption is used.
+
+ - With repeated universal argument - equal to 16 - then the key cache is
+   cleared before any encryption transformations, to force prompting of the
+   user for the key.
+
+The solicited key is retained for reuse in a buffer-specific cache for some
+set period of time \(default, 60 seconds), after which the string is
+nulled.  `mailcrypt' provides the key caching functionality.  You can
+adjust the key cache timeout by ajdusting the setting of the elisp variable
+`mc-passwd-timeout'.
+
+If the file previously had no associated key, or had a different key than
+specified, the user is prompted to repeat the new one for corroboration.  A
+random string encrypted by the new key is set on the buffer-specific
+variable `allout-key-verifier-string', for confirmation of the key when
+next obtained, before encrypting or decrypting anything with it.  This
+helps avoid mistakenly shifting between keys.
+
+If allout customization var `allout-key-verifier-handling' is non-nil, an
+entry for `allout-key-verifier-string' and its value is added to an Emacs
+'local variables' section at the end of the file, which is created if
+necessary.  That setting is for retention of the key verifier across emacs
+sessions.
+
+Similarly, `allout-key-hint-string' stores a user-provided reminder about
+their key, and `allout-key-hint-handling' specifies when the hint is
+presented, or if key hints are disabled.  If enabled \(see the
+`allout-key-hint-handling' docstring for details), the hint string is
+stored in the local-variables section of the file, and solicited whenever
+the key is changed."

+;;; This routine handles allout-specific business, dispatching
+;;; encryption-specific business to allout-encrypt-string.

	* allout.el: omnibus changes

	  - new subsystem supporting easy gpg topic encryption/decryption.

	    salient features:

	    - both public- and symmetric-key modes are supported.
	    - encryption being on a per-topic basis means you can
	      intersperse encrypted and clear-text data in a single file
	      to your heart's content.
	    - user-provided symmetric-key hints, with consistency
	      verification to help user avoid confusion
	    - time-limited key reuse, a la (and using) mailcrypt's
	      mc-passwd-timeout
	    - write-file-hook and auto-save-hook activities to support auto
	      encryption of pending topics on save; provision to skip
	      currently-edited topic to avoid editing disturbance

	    topic encryption functionality depends on both mailcrypt and
	    crypt++ packages.  (non-encryption allout functionality is not
	    disrupted if either mailcrypt or crypt++ are absent.)

	    `allout-toggle-current-subtree-encryption' is the central
	    routine.

	    there are a five new encryption customization variables:

	    - allout-topic-encryption-bullet
	    - allout-default-encryption-scheme
	    - allout-key-verifier-handling
	    - allout-key-hint-handling
	    - allout-encrypt-unencrypted-on-saves

	    topic encryption is included in mouse menu

	    docstring for `allout-toggle-current-subtree-encryption'
	    and customization variables provide detailed description.

	  - repaired inhibition of concealed-text edits

	    this helps preserve the structural integrity of outlines, as
	    well as preventing insidiously invisible accidental edits

	    (it also noticably slows massive exposure changes, but i
	    consider the performance acceptable.  eg, i have blanket
	    auto-exposure set for my daily-notes log, which has real-world
	    intricacy in a 1.1 Mb, 7000 topic outline, and have no problems
	    working with it on a 200 MhZ windows laptop.)

	  - disallow manually shifting a topic deeper than the offspring
	    depth of the previous topic - avoiding confusing "containment
	    discontinuities"

	  - fixed retention of body relative hanging indent during
	    promotion of collapsed bodies

	  - made it easy to open new topic with same bullet as current
	    topic - topic creation functions provided with any universal
	    argument provokes now prompt for bullet, defaulting to the
	    bullet of the previous topic.  very ergonomic.

	  - plain bullet alternates '.' period and ',' comma only.  all
	    other bullets are relegated to special status (but customizable)

	  - comments and routine names better distinguish between:
	    - topic body - the text contained after a header
	    - topic header - the first line, before the body
	    - topic entry - the header, body, and offspring

	  - allout-beginning-of-current-entry now works as advertised

	  - allout-end-of-current-entry relieved of superfluous
	    allout-show-entry

	  - reconciled with distributed allout.el 1.61 (current CVS version
	    as of 09/30/2005), including interactive-p fixes, typo and
	    coding style fixes, change of function prefix to "allout-", etc,
	    and fixed problem created in outline yanking due to the
	    interactive-p fixes

	  - relocated some macros

	  - refined many docstrings, including anything from correcting
	    typos to conceptual clarification and correction

	  - corrected commentary 'keywords' to legitimate ones

	  - updated comentary author info (using my current email address,
            obscurified)
