KPCLI-2.7(1) User Contributed Perl Documentation KPCLI-2.7(1) NAME kpcli - A command line interface to KeePass database files. DESCRIPTION A command line interface (interactive shell) to work with KeePass database files (http://http://en.wikipedia.org/wiki/KeePass). This program was inspired by my use of "kedpm -c" combined with my need to migrate to KeePass. The curious can read about the Ked Password Manager at http://kedpm.sourceforge.net/. USAGE Please run the program and type "help" to learn how to use it. PREREQUISITES This program requires these non-core modules: "Crypt::Rijndael" - libcrypt-rijndael-perl on Ubuntu 10.04 "Term::ReadKey" - libterm-readkey-perl on Ubuntu 10.04 "Sort::Naturally" - libsort-naturally-perl on Ubuntu 10.04 "File::KeePass" - libfile-keepass-perl on Ubuntu 12.04 "Term::ShellUI" - libterm-shellui-perl on Ubuntu 12.10 It is recommended that you install "Term::ReadLine::Gnu" which will provide more fluid signal handling on Unix-like systems, making kpcli robust to suspend, resume, and interupt - SIGSTP, SIGCONT and SIGINT. That module is in the libterm-readline-gnu-perl package on Ubuntu. You can optionally install "Clipboard" and "Tiny::Capture" to use the clipboard features; http://search.cpan.org/~king/Clipboard/ and libcapture-tiny-perl on Ubuntu 10.04. You can optionally install "Data::Password" to use the pwck feature (Password Quality Check); libdata-password-perl on Ubuntu 10.04. On MS Windows, you can optionally install "Win32::Console::ANSI" to get ANSI colors in Windows cmd terminals. Strawberry Perl 5.16.2 was used for the kpcli port to Windows and, using cpanminus, one can install all of kpcli's dependencies, sans Term::ReadLine::Gnu which is optional for kpcli and not supported on MS Windows. CAVEATS AND WORDS OF CAUTION The main author of kpcli primarily interoperability tests with KeePassX (http://www.keepassx.org/) and primarily uses KeePass v1 (*.kdb) files. Support for KeePass v2 (*.kdbx) files in kpcli is substantial, and many people use it daily, but it is not the author's primary use case. It is also the author's intent to maintain compatibility with v1 files, and so anyone sending patches, for consideration for inclusion in future kpcli versions, is asked to validate them with both v1 and v2 files. No history tracking for KeePass 2 (*.kdbx) files Recording entries' history in KeePass 2 files is not implemented. History that exists in a file is not destroyed, but results of entry changes made in kpcli are not recorded into their history. Prior-to- change copies are stored into the "Recycle Bin." Note that File::KeePass does not encrypt passwords of history entries in RAM, like it does for current entries. This is a small security risk that can, in theory, allow priviledged users to steal your passwords from RAM, from entry history. File::KeePass bug prior to version 2.03 Prior to version 2.03, File::KeePass had a bug related to some "unknown" data that KeePassX stores in group records. For File::KeePass < v2.03, kpcli deletes those unknown data when saving. Research in the libkpass (http://libkpass.sourceforge.net/) source code revealed that what early versions of File::KeePass classifies as "unknown" are the times for created/modified/accessed/expires as well as "flags" (id=9), but only for groups; File::KeePass handled those fields just fine for entries. I found no ill-effect from dropping those fields when saving and so that is what kpcli does to work around the File::KeePass bug, if kpcli is using File::KeePass < v2.03. BUGS Using Ctrl-D to Exit Versions of Term::ShellUI prior to v0.9. do not have the ability to trap Ctrl-D exits by the client program. I submitted a patch to remedy that and it made it into Term::ShellUI v0.9. Please upgrade if kpcli asks you to. Multiple Entries or Groups With the Same Name in the Same Group This program does not support multiple entries in the same group having the exact same name, nor does it support multiple groups at the same level having the same name, and it likely never will. KeepassX does support those. This program detects and alert when an opened database file has those issues, but it does not refuse to save (overwrite) a file that is opened like that. Saves are actually safe (no data loss) as long as the user has not touched one of the duplicately-named items. AUTHOR Lester Hightower <hightowe at cpan dot org> LICENSE This program may be distributed under the same terms as Perl itself. CREDITS Special thanks to Paul Seamons, author of "File::KeePass", and to Scott Bronson, author of "Term::ShellUI". Without those two modules this program would not have been practical for me to author. CHANGELOG 2010-Nov-28 v0.1 - Initial release. 2010-Nov-28 v0.2 - Encrypt the master password in RAM. 2010-Nov-29 v0.3 - Fixed master password encryption for saveas. 2010-Nov-29 v0.4 - Fixed code to work w/out Term::ReadLine::Gnu. Documented File::KeePass v0.1 hierarchy bug. 2010-Nov-29 v0.5 - Made find command case insensitive. Bugfix in new command (path regex problem). 2010-Nov-29 v0.6 - Added lock file support; warn if a lock exists. 2010-Dec-01 v0.7 - Further documented the group fields that are dropped, in the CAVEATS section of the POD. Sort group and entry titles naturally. 2010-Dec-23 v0.8 - Worked with File::KeePass author to fix a couple of bugs and then required >=v0.03 of that module. Sorted "/_found" to last in the root group list. Fixed a "database changed" state bug in cli_save(). Made the find command ignore entries in /Backup/. Find now offers show when only one entry is found. Provided a patch to Term::ShellUI author to add eof_exit_hook and added support for it to kpcli. 2011-Feb-19 v0.9 - Fixed bugs related to spaces in group names as reported in SourceForge bug number 3132258. The edit command now prompts to save on changes. Put scrub_unknown_values_from_all_groups() calls back into place after realizing that v0.03 of File::KeePass did not resolve all of the problems. 2011-Apr-23 v1.0 - Changed a perl 5.10+ regex to a backward-compatable one to resolve SourceForge bug number 3192413. Modified the way that the /Backup group is ignored by the find command to stop kpcli from croaking on multiple entries with the same name in that group. - Note: There is a more general bug here that needs addressing (see BUGS section). An empty title on new entry aborts the new entry. Changed kdb files are now detected/warned about. Tested against Term::ShellUI v0.9, which has my EOF hook patch, and updated kpcli comments about it. Term::ShellUI's complete_history() method was removed between v0.86 and v0.9 and so I removed kpli's call to it (Ctrl-r works for history). Added the "icons" command. 2011-Sep-07 v1.1 - Empty DBs are now initialized to KeePassX style. Fixed a couple of bugs in the find command. Fixed a password noecho bug in the saveas command. Fixed a kdb_has_changed bug in the saveas command. Fixed a cli_open bug where it wasn't cli_close'ing. Fixed variable init bugs in put_master_passwd(). Fixed a false warning in warn_if_file_changed(). 2011-Sep-30 v1.2 - Added the "export" command. Added the "import" command. Command "rmdir" asks then deletes non-empty groups. Command "new" can auto-generate random passwords. 2012-Mar-03 v1.3 - Fixed bug in cl command as reported in SourceForge bug number 3496544. 2012-Apr-17 v1.4 - Added key file support based on a user contributed patch with SourceForge ID# 3518388. Added my_help_call() to allow for longer and more descriptive command summaries (for help command). Stopped allowing empty passwords for export. 2012-Oct-13 v1.5 - Fixed "help <foo>" commands, that I broke in v1.4. Command "edit" can auto-generate random passwords. Added the "cls" and "clear" commands from a patch with SourceForge ID# 3573930. Tested compatibility with File::KeePass v2.03 and made minor changes that are possible with >=2.01. With File::KeePass v2.03, kpcli should now support KeePass v2 files (*.kdbx). 2012-Nov-25 v1.6 - Hide passwords (red on red) in the show command unless the -f option is given. Added the --readonly command line option. Added support for multi-line notes/comments; input ends on a line holding a single ".". 2013-Apr-25 v1.7 - Patched to use native File::KeePass support for key files, if the File::KeePass version is new enough. Added the "version" and "ver" commands. Updated documentation as Ubuntu 12.10 now packages all of kpcli's dependencies. Added --histfile command line option. Record modified times on edited records, from a patch with SourceForge ID# 3611713. Added the -a option to the show command. 2013-Jun-09 v2.0 - Removed the unused Clone module after a report that Clone is no longer in core Perl as of v5.18.0. Added the stats and pwck commands. Added clipboard commands (xw/xu/xp/xx). Fixed some long-standing tab completion bugs. Warn if multiple groups or entries are titled the same within a group, except for /Backup entries. 2013-Jun-10 v2.1 - Fixed several more tab completion bugs, and they were serious enough to warrant a quick release. 2013-Jun-16 v2.2 - Trap and handle SIGINT (^C presses). Trap and handle SIGTSTP (^Z presses). Trap and handle SIGCONT (continues after ^Z). Stopped printing found dictionary words in pwck. 2013-Jul-01 v2.3 - More readline() and signal handling improvements. Title conflict checks in cli_new()/edit()/mv(). Group title conflict checks in rename(). cli_new() now accepts optional path&|title param. cli_ls() can now list multiple paths. cli_edit() now shows the "old" values for users to edit, if Term::ReadLine::Gnu is available. cli_edit() now aborts all changes on ^C. cli_saveas() now asks before overwriting a file. 2013-Nov-26 v2.4 - Fixed several "perl -cw" warnings reported on 2013-07-09 as SourceForge bug #9. Bug fix for the cl command, but in sub cli_ls(). First pass at Strawberry perl/MS Windows support. - Enhanced support for Term::ReadLine::Perl - Added support for Term::ReadLine::Perl5 Added display of expire time for show -a. Added -a option to the find command. Used the new magic_file_type() in a few places. Added generatePasswordFromDict() and "w" generation. Added the -v option to the version command. - Added the versions command. 2014-Mar-15 v2.5 - Added length control (gNN) to password generation. Added the copy command (and cp alias). Added the clone command. Added optional modules not installed to version -v. Groups can now also be moved with the mv command. Modified cli_cls() to also work on MS Windows. Suppressed Term::ReadLine::Gnu hint on MS Windows. Suppressed missing termcap warning on MS Windows. Print a min number of *s to not leak passwd length. Removed unneeded use of Term::ReadLine. Quieted "inherited AUTOLOAD for non-method" warns caused by Term::Readline::Gnu on perl 5.14.x. 2014-Jun-06 v2.6 - Added interactive password generation ("i" method). - Thanks to Florian Tham for the idea and patch. Show entry's tags if present (KeePass >= v2.11). - Thanks to Florian Tham for the patch. Add/edit support for tags if a v2 file is opened. Added tags to the searched fields for "find -a". Show string fields (key/val pairs) in v2 files. Add/edit for string fields if a v2 file is opened. Show information about entries' file attachments. 2014-03-20 SourceForge feature request #6. New "attach" command to manage file attachments. Added "Recycle Bin" functionality and --no-recycle. For --readonly, don't create a lock file and don't warn if one exists. 2014-03-27 SourceForge bug #11. Added key file generation to saveas and export. 2014-04-19 SourceForge bug #13. Added -expired option to the find command. Added "dir" as an alias for "ls" Added some additional info to the stats command. Added more detailed OS info for Linux/Win in vers. Now hides Meta-Info/SYSTEM entries. Fixed bug with SIGTSTP handling (^Z presses). Fixed missing refresh_state_all_paths() in cli_rm. 2014-Jun-11 v2.7 - Bug fix release. Broke the open command in 2.6. TODO ITEMS Consider adding a purge command for "Backup"/"Recycle Bin" folders. Consider adding a tags command for use with v2 files. - To navigate by entry tags Consider supporting KeePass 2.x style entry history. - There are potential security implications in File::KeePass. - Related, consider adding a purge command for that history. Consider adding KeePass 2.x style multi-user synchronization. Consider http://search.cpan.org/~sherwin/Data-Password-passwdqc/ for password quality checking. Consider adding searches for created, modified, and accessed times older than a user supplied time. Consider adding import support for Password Safe v3 files using http://search.cpan.org/~tlinden/Crypt-PWSafe3/. May have already done this if the unpackaged dependencies list was not so long. OPERATING SYSTEMS AND SCRIPT CATEGORIZATION Unix-like - Originally written and tested on Ubuntu Linux 10.04.1 LTS. - As of version 2.5, development is done on Linux Mint 16. - Known to work on many other Linux and *BSD distributions, and kpcli is packaged with many distributions now-a-days.
