There are several interfaces to do so:\n\n* Tag-wide encryption/decryption with a macro:\n\n{{{<<<encrypt_tag "tagname" "password-realm" "button text">>>}}}\n\nAs shown above, passwords are cached on a per-zone basis where a zone may be\nsomething like "work" or "home". This does not have to have any relation to\nyour tag, but if omitted, will be the same.\n\n* If you're done encrypting/decrypting, you may want to clear the cached password. This can be done with another button creating macro:\n\n{{{<<<encrypt_clear "password-realm">>>}}}\n\n* If you want to take a peek at some encrypted data without fear of saving it, you can add a preview button to your toolbar. If you are using the normal ViewTemplate, just add ''peekcrypt'' like below:\n\n{{{<div class='toolbar' macro='toolbar ... peekcrypt>...}}}\n\n* If you want to just encrypt/decrypt one tiddler at a time, you can add an\n ''autocrypt'' button to the toolbar:\n\n{{{<div class='toolbar' macro='toolbar ... autocrypt>...}}}\n\n* Note: the entropy collection is not particularly great so far. If this is very sensitive datæ, you may want to consider a more secure solution or help beef this one up!\n\n\n!!!!!Options\n<<option chkEncryptTags>> Encrypt tiddler tags\n<<option chkEncryptTitles>> Encrypt tiddler titles and references\n\n!!!!!TODO\n* Add versioning and reader/writer for encrypted tiddlers w.out needing a tag.\n* Figure out a better entropy system - look at Clipperz\n* Encrypt-on-save: auto re-encrypt specifically tagged items\n** Alternately add a decrypt-to-edit/encrypt-on-save for a specific tiddler\n* Add toolbar commands for encrypt/decrypt\n* Embed per-tiddler encryption options and autodetect otherwise\n* Add macro-wrapped encryption (think tasklist/tasksum)\n* Make previews more like light boxes\n* Encrypt all object data for a tiddler and not just text/title/tags (JSON?)\n* Compressed or minjs'd code\n* Make reference title-encryption replacement safer (e.g. proper replace())\n* Clean up code encapsulation some more\n* Automatic password updating (e.g. decrypt/re-encrypt all tiddlers)\n* Configurable key bits (allow user to use stronger keys than 128 bit)\n* Local-file key support (load a key file that is optionally password-protected)\n* Encapsulate the rumsby's entropy collector slightly better\n\n<<<\n!!!!!Installation\n<<<\nimport (or copy/paste) the following tiddlers into your document:\n''EncryptTiddlerPlugin'' (tagged with <<tag systemConfig>>)\n<<<\n!!!!!Revisions\n<<<\n!''2007.02.20 [0.0.3]''\n* Added EncryptionPayload: an extensible payload object for safe forward compat\n* Cleaned up peekcrypt and the askUser object\n* Added support for encrypt/decrypt in the toolbar: autocrypt\n!''2007.02.18 [0.0.2]''\n* Added informational messages\n* Added AESprng from Steve Rumsby's Encryption plugin\n* Namespaced the Rijndael plugin on ''Rijndael''\n* Added .encrypt/.decrypt to Tiddler prototype\n* Kinda encapsulated my code in encryptionPlugin\n* Moved encrypted zone name into the encrypted tiddler to make previewing easy\n* Added previewSecret toolbar command to allow previewing of data\n* Added two checkbox options: encrypt tags and encrypt titles\n* Separate tag-wide encryption from password zones/realms. encrypt_tag now supports that.\n* Updated the usage a little bit\n* Added a loop which ensures that entropy collection continues.\n'!'2007.02.15 [0.0.1]''\n* first cut.\n<<<\n!!!!!Credits\n>Based on copyTiddlerPlugin developed by EricShulman from [[ELS Design Studios|http://www.elsdesign.com]]\n>AES implementation courtesy of Fritz Schneider.

Also includes diagnostic tools to help you debug your TiddlyWiki problems by letting you view current TiddlyWiki internal option values, messages, shadows, stylesheets, notify and macro functions or display the internal DOM (Document Object Model) tree structure for any specific part of the TiddlyWiki document.\n!!!!!Configuration\n<<<\nAutomatically freeze preview updates when a tiddler takes more than <<option txtTidIDEAutoFreeze>> milliseconds to render.\n<<<\n!!!!!Usage/Example\n<<<\n{{{<<tidIDE id:example "font:Courier New" size:8pt system +edit:GettingStarted>>}}}\n<<tidIDE id:example "font:Courier New" size:8pt system +edit:GettingStarted>>\n!!!!!parameters:\n* ''id'' - assign a unique ID to this instance of TidIDE. (default id=current tiddler title or "" if not in a tiddler)\n* ''font'' - sets the CSS font-family used by textarea controls in editor and system information panels. Note: if the font name includes a space (e.g., Courier New), then you must enclose the entire parameter in double-quotes: {{{"font:Courier New"}}}.\n* ''size'' - sets the CSS font-size used by text input and droplist controls in editor and system information panels.\n* ''system'' includes system information panel.\n* ''edit'' includes tiddler editor/previewer.\n**''edit:here'' automatically sets the editor to show the current tiddler contents (if in a tiddler)\n**''edit:tiddlertitle'' automatically sets the editor to show the specified tiddler contents\n* use ''{{{[[label|tiddlertitle]]}}}'' to include 'custom panels' (and corresponding labelled checkboxes to toggle their display)\n* all parameters are optional. The default panel is "edit:here".\n* panel parameters preceded by a "+" are displayed by default. If only one panel specified in the parameters, it is automatically displayed, even if the "+" is omitted.\n!!!!!using the editor\nThe editor includes a droplist of all tiddlers in the document, sorted alpha-numerically by tiddler title. Shadow tiddlers that have not been customized are added to the end of this list and marked with "(shadow)". Next to the droplist are several buttons:\n* ''view'' opens the tiddler in the normal ~TiddlyWiki display area\n* ''add'' prompts for a new tiddler title and begins a new editing session\n* ''remove'' deletes an existing tiddler (note: shadow tiddlers cannot be removed)\n* ''save'' saves changes to the tiddler currently being edited\n* ''save as'' saves changes using a new tiddler title\nIf a tiddlername was not specified in the macro, select a tiddler from the droplist (or press ''add'') to begin editing. Once a tiddler has been loaded into the editor, you can change it's content, enter or select tags.\n\nNormally, when you save changes to a tiddler, the created/modified dates and tiddler author are automatically updated. However, it is sometimes useful to make small changes to a tiddler without automatically updating the date/author information. Select the ''minor edits'' checkbox to prevent those values from being //automatically// changed. In addition, this enables the date/author edit fields which allows you to //manually// 'back date' a tiddler or change the author to another name. When the tiddler is saved, the date/author values shown in the edit fields will be used.\n!!!!!using the previewer\nThe ''preview'' checkbox adds a display area that shows you what your tiddler changes will look like, //before// committing to those changes.\n\nBy default, this preview display is automatically rendered each time a key is typed into the tiddler content edit field. As soon as changes are entered, they will be instantly visible within the preview display. Unfortunately, the partial tiddler source definitions that occur //during// editing may somtimes cause rendering problems, and some exceptionally complex tiddlers make take an unusually long amount of time to completely render their content. In such cases, key-by-key display updates are undesirable or impractical.\n\nWhen ''preview'' is selected, you can also select ''freeze'' to suspend automatic key-by-key preview display updates. The preview display will not be re-rendered again until you press the ''refresh'' button, or clear the 'freeze' checkbox, or switch to editing a different tiddler. The editor automatically freezes the preview display whenever the //rendering time// exceeds a pre-determined time limit (see configuration section), specified in milliseconds. Note: the ''actual elapsed time'' used to process and render any given tiddler is reported in the browser's status bar area whenever that tiddler is previewed.\n\nThe previewer also can display a ''DOM viewer'' and an ''HTML viewer'' that are also updated with each keystroke. These text-based displays can be helpful while attempting to correct or enhance the formatting of tiddler content, especially when complex combinations of wiki-syntax produce unexpected or undesired results.\n!!!!!system information and TW option settings\nYou can use the ''system information'' panel to view a variety of system internal data and functions, and view/modify ''all'' of ~TiddlyWiki's internal config.option.* settings. NOTE: Non-default config.options are stored in cookies and are retrieved whenever the TW document is loaded into a browser; however, ''core TW functions and custom-defined plugins can explicitly ignore or reset any locally-stored cookie values and use their own, internally-defined values'' instead. As a result, changes to these may be completely ignored, or may only have an effect during the current TW document "session" (i.e., until the TW document is reloaded), even though a persistent cookie value has been saved.\n!!!!! ~DOMViewer macro\nsyntax: {{{<<DOMViewer rows:nn indent:xxxx inline path elementID|tiddlertitle>>}}}\n\nWhenever TiddlyWiki renders a given tiddler, it creates a 'tree' of DOM (Document Object Model) elements that represent the information that is displayed by the browser. You can use the ''DOMViewer'' macro to examine the internal DOM elements that are produced by TiddlyWiki's formatter (the 'wikifier'), or elements directly produced by embedded macros that create custom formatted output. This can be particularly helpful when trying to fine tune the layout and appearance of your tiddler content.\n\nDOMViewer creates a textarea control and reports the DOM tree for the current 'insertion point' where the DOMViewer macro is being placed. ''inline'' flag uses TiddlyWiki rendering instead of textarea control. ''path'' shows the relative location of each child element in the DOM tree, using subscript notation, ''[elementID or tiddlertitle]'' displays DOM elements starting from the node with the specified ID. If that ID is not found in the DOM tree, the macro attempts to open a tiddler with that title and then displays the "tiddler"+title DOM elements that were rendered.\n<<<\n!!!!!Installation\n<<<\nimport (or copy/paste) the following tiddlers into your document:\n''TidIDEPlugin'' (tagged with <<tag systemConfig>>)\n^^documentation and javascript for macro handling^^\n<<<\n!!!!!Revision History\n<<<\n''2006.12.09 [1.6.1]'' in handler(), allow non-existing tiddler title when processing "edit:title" param\nso that new tiddler (or journal) can be created directly from newTiddler, newJournal, or tidIDE macro (without pressing "new" button).
