Pure Plain Text Notes... with optional encryption.
https://github.com/clach04/puren_tonbo/
IMPORTANT before using the optionally encryption features, ensure that it is legal in your country to use the specific encryption ciphers. Some countries have also have restrictions on import, export, and usage see http://www.cryptolaw.org/cls-sum.htm

Has similar parameters for ease of switching.
Python 2.7 note for Windows. Non-ascii characters can cause Python exception/crashes UnicodeEncodeError when attempting to print Unicode characters, where as Python 3 does not. ptgrep implements a translation feature/hack which can be disabled (or tweaked) via the Operating System environment variable PTGREP_STDOUT_MODE. Valid options are disabled, utf8, and ascii:backslashreplace. For Python 2.7 under Microsoft Windows **only** (when neither PYTHONIOENCODINGnorPYTHONUTF8have been set)ascii:backslashreplaceis the default and works in a similar fashion toPYTHONIOENCODING`.

ptpyvim
python -m puren_tonbo.tools.ptpyvim
ptcipher is a tool for dealing with raw (binary, i.e. bytes rather than characters) files for encryption/decryption. All options are controlled via command line flag and operating system environment variables.
Assuming installed:
ptcipher -h
From source code checkout:
python -m puren_tonbo.tools.ptcipher -h
python2 -m puren_tonbo.tools.ptcipher -h
python3 -m puren_tonbo.tools.ptcipher -h
Quick demo:
ptcipher --password password --decrypt puren_tonbo/tests/data/aesop.chi
ptcipher --password password --decrypt puren_tonbo/tests/data/aesop_linux_7z.aes256.zip
python -m puren_tonbo.tools.ptcipher --password password --decrypt puren_tonbo/tests/data/aesop.chi
Symmetric encryption/decryption from passphase.
Compatible with http://tombo.osdn.jp/En/ (and others, for example, Kumagusu on Android).
ptcipher -e -p test README.md -o README.chi
ptcipher -v -p test README.chi
The chi file can also be read/written by Tombo http://tombo.sourceforge.jp/En/ and clones
Symmetric encryption/decryption from passphase.
Tested with ccrypt 1.11 and 1.10 (32-bit and 64-bit Intel x86/x64 and arm).
Requires a ccrypt binary, download from https://ccrypt.sourceforge.net/
(or debian apt). ccrypt binary/executable needs to be in the path or
the environment variable CCRYPT_EXE needs to have the (full) path.
NOTE Under Microsoft Windows, is the ccrypt.exe is in a path with
spaces, do NOT use double quotes in the SET. Example: set CCRYPT_EXE=C:\3rd party bins\ccrypt.exe
python -m puren_tonbo.tools.ptcipher --password password puren_tonbo/tests/data/aesop_win_ccrypt.cpt

Symmetric encryption/decryption from passphase, key support not explictly implemented.
Requires a gpg binary, download from https://gnupg.org/download/
python -m puren_tonbo.tools.ptcipher --cipher=asc -e -p test README.md -o README.asc
python -m puren_tonbo.tools.ptcipher --cipher=gpg -e -p test README.md -o README.gpg

OpenSSL 1.1.0+ compatible (with a very small subset of options).
ptcat --note-root=. puren_tonbo/tests/data/aesop_win.openssl_aes256cbc_pbkdf2_10k
Intended to allow decryption of files generated with OpenSSL 1.1.0 and vice-versa. Supported OpenSSL flags/formats:
openssl enc -e aes-256-cbc -salt -pbkdf2 -iter 10000 -in in_file -base64 -out out_file
openssl dec -d aes-256-cbc -salt -pbkdf2 -iter 10000 -in in_file -base64 -out out_file
echo hello| openssl enc -e aes-256-cbc -salt -pbkdf2 -iter 10000 -in - -base64 -out - -pass pass:password
echo hello| openssl enc -e -aes-256-cbc -in - -out - -salt -pbkdf2 -iter 10000 -pass pass:password
NOTE PBKDF2 iteration count of 10,000 is the default in OpenSSL 1.1.1 and is considered too few in 2023. Older versions of OpenSSL did not support; PBKDF2 (and ergo iterations) and salt and used a much weaker KDF.
Supports binary/raw and base64 encoded/ASCII armored files. ONLY supports aes-256-cbc with salt and pbkdf2 KDF with 10,000 interations.
Symmetric encryption/decryption from passphase.
ptcipher -e -p test README.md -o README.aes256.zip
ptcipher -p test README.aes256.zip
The aes256.zip file can also be read/written by 7-Zip, WinRAR, WinZIP, etc. that support AES zip files.
For example, 7z can read and write AES zip files:
7z a -tzip -mem=AES256 -ptest README.aes256.zip README.md
7z x -ptest README.aes256.zip
Symmetric encryption/decryption from passphase.
NOTE not implemented in nvim / neovim.
In vim the easiest way to get the newest encryption mode/format, for a file:
vim -c ":setlocal cm=blowfish2" test.vimcrypt3
then issue:
:X
will be prompted for password, can then edit/save as per normal.
To see encryption mode:
:setlocal cm?
ptcipher demo:
python -m puren_tonbo.tools.ptcipher -p test test.vimcrypt3
Quick and easy view/read ONLY of encrypted file with vim, without updating vim config.
NOTE call vim (or neovim) with options to set "private" mode:
-to read from stdin instead of a filename, avoid plaintext hitting the disk-nturns off swap file - use memory only-iturns off .viminfo
TODO disable undo file
-
Use a pipe (cross platform)
ptcat FILE | vim - -n -i "NONE" -
Use bash shell process substitution feature for editors that don't support stdin (Linux/Unix only, avoids directly calling mkfifo and cleaning up named pipes)
scite < (ptcat FILE) ptcat FILE | scite /dev/stdin scite <(python -m puren_tonbo.tools.ptcat puren_tonbo/tests/data/aesop.txt)
Puren Tonbo will prompt for passwords and the decrypted content should not hit the file system.
Option 1 can be used with other tools that take in stdin, option 2 can be used with any tool that takes in a filename.
Caution!
- don't save the raw file
- ensure now backup, swap, undo file, etc.. get created

Tested with versions: v4.0.0, 4.1.5, and 5.3.5
See pt_scite.lua - read and write support (tested Windows). NOTE due to lua popen() any helpful error text/information is missing. Diagnosing failures can be difficult, even for trivial errors like directory/disk does not exist as this is not reported to the lua runtime. Also see SciTE Python plugin for read and write support with stderror support.
By default uses ptcipher in path, override via PTCIPHER_EXE environment variable.
Does NOT prompt for password, requires setting PT_PASSWORD environment variable or use of keyring.
- Can be used standalone or with ParsKorata (http://lua-users.org/wiki/ParsKorata) mini/simple ExtMan compatible script
- Untested with ExtMan - http://lua-users.org/wiki/SciteExtMan
Need to edit SciTEUser.properties:
- Windows
%USERPROFILE%"\SciTEUser.propertiesor%APPDATA%\scite\SciTEUser.properties
- Unix
~/.SciTEUser.propertiesor$HOME/.SciTEUser.properties
Alternatively, launch scite, then open Options, Open User (or GLobal) Options File.
Windows NOTE to avoid a (typically black) CMD/Command window showing up use SciTE 4.4.4 or later and set create.hidden.console in SciTEUser.properties:
# https://groups.google.com/g/scite-interest/c/QOhizNSEejU/m/qXslloxnCgAJ
# SciTE 4.4.4 on Windows adds create.hidden.console option to stop console window flashing when Lua script calls os.execute or io.popen.
create.hidden.console=1
# TODO see if this can be set in lua code, to make config easier
If not using a plugin extension manager can simply set pt_scite.lua as starting lua script.
Edit SciTEUser.properties to set lua script:
...
ext.lua.startup.script=C:\code\py\puren_tonbo\pt_scite.lua
create.hidden.console=1
...
If using an extman like system:
...
# This is a simplified ExtMan
# requires each plugin/add-on to be "registered" or declared, white listed, etc.
ext.lua.startup.script=C:\code\scite\extman\parskorata_extman.lua
...
Then edit parskorata_extman.lua to add to end:
mgr:load_files{'pt_scite.lua'}
NOTE not needed with original full ExtMan.
See scite with Python README - read and write support, Windows only (needs polishing).
By default uses ptcipher in path, override via PTCIPHER_EXE environment variable.
Does NOT prompt for password, requires setting PT_PASSWORD environment variable.
Tested under Linux with vim 8.0 and 8.1. under x86, x64, and arm 32-bit.
See pt.vim - Linux/Unix/Cygwin only for now.
By default uses ptcipher in path, override via PTCIPHER_EXE environment variable.
Will prompt for password, which can be skipped by setting PT_PASSWORD environment variable.
Assuming puren_tonbo has been installed and ptcipher is in the
path (and in source code checkout):
vim -u pt.vim puren_tonbo/tests/data/aesop.chi
And enter in the test password, password.
As per example above, can use the -u parameter but this overrides existing settings.
Vim 8 supports plugins packs, to install:
If you do not already have any plugin packs, need to create directory, e.g.:
mkdir -p ~/.vim/pack/bundle/start/
Where bundle is user decided. For the rest of the documentation replace bundle with your directory name.
Install from checkout:
mkdir -p ~/.vim/pack/bundle/start/puren_tonbo/plugin/
cp pt.vim ~/.vim/pack/bundle/start/puren_tonbo/plugin/
Then can call vim without -u:
vim puren_tonbo/tests/data/aesop.chi
gvim puren_tonbo/tests/data/aesop.chi
NOTE not working under Windows :-( Appear to be buffered files issues with vim/python interaction.
See linux notes, instead of ~/.vim use %USERPROFILE%\vimfiles (or $VIM_INSTALLATION_FOLDER\vimfiles)
mkdir %USERPROFILE%\vimfiles\pack\bundle\start\puren_tonbo\plugin
copy pt.vim %USERPROFILE%\vimfiles\pack\bundle\start\puren_tonbo\plugin
See https://vim.fandom.com/wiki/Encryption for how to configure vim with external tools for (view and edit) of encrypted files with autocmd. NOTE under Windows buffered IO can interfere with vim interactions. TODO consider using (OpenSSL) https://www.vim.org/scripts/script.php?script_id=2012 as a model for vim plugin (uses functions), also see:
- https://aweirdimagination.net/2019/03/24/encrypted-files-in-vim/ https://git.aweirdimagination.net/perelman/openssl.vim
- https://github.com/MoserMichael/vimcrypt2.
Puren Tonbo is implemented in Python, with support for Python 3.x and 2.7.
python -m puren_tonbo.tests.testsuite
python -m puren_tonbo.tests.testsuite -v 2>&1 |grep -i skipped
All encryption/decryption is file object based.
Low level routines (EncryptedFile) use file-like objects, for in-memory encryption/decryption use BytesIO
(see test suite, puren_tonbo/tests/testsuite.py).
There is also the note abstraction (FileSystemNotes) which is filename based.
