5.1.4 AI
September 27, 2025
New features: 
  •	New external language files have been added. With the newest AI translators, we have made translations into more than 30 of the most relevant languages as suggested by ChatGPT (Arabic, Belarusian, Bulgarian, Croatian, Czech, Danish, English, Esperanto, Finnish, French, German, Greek, Hebrew, Hungarian, Chinese-Simplified, Chinese-Traditional, Italian, Japanese, Korean, Latin, Norwegian, Persian, Polish, Portuguese-Brasil, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, Turkish, Ukrainian, Vietnamese) 
  •	You can edit the AI translation (Google Translate, DeepL, M-Copilot, ChatGPT) via the direct button in the menu. If you will publish your work to other people speaking your language, send an edited translation to translate@artbymind.com
   	Motivation: For sending a high-quality corrected translation, you get a very strong license for free.
  •	If the opened file as a parameter is a bookmark (*.sbk), then the files stored in it will also be opened
Miscellaneous: 
  •	Modified configuration in the batch file ("OpenAtCursor.bat") 
  •	Safe Notes has new support for over 30 languages that costs over 5000 euros. Please donate if you can.
Info: 
  •	The AI tag stands for Application Improvement. Details can be found below.

August 6, 2025
New features: 
  •	Added Drag&Drop feature for files selection to Signature-Tool and Encryption-Tool
  •	Added new setting in options: Allow one/multiple instances of SafeNotes (previous versions always check if the application is already running)
  •	Added new button to the button bar: Disable clipboard encryption (or enable if disabled)
  •	When reloading a safe file, memory wipe is added (same as when closing a document)
  •	Opening a file at the cursor position: Added detection of IP path e.g. "\\192.168.10.182\Temp\image.png"
Safe Signatures:
  •	Added LargoWAV support for up to 256TB wav-file length. The official LargoWav specification is attached to the documentation directory (LargoWAV.pdf).

  •	Added DFF support for Philips lossless uncompressed/compressed 1-bit DSD/DST.
  •	Added automatic conversion of DSF and DFF stereo files from MSB to LSB and to blocks of size 4096 before hashing. This will allow direct comparison of 1-bit audio DSD files in different containers.
  •	Added support for audio hashing over 4GB of raw audio length for WAV/FLAC/APE.
  •	If an audio file is detected and audio processing is not allowed, the question is whether to enable it.
  •	If an audio file is processed, immediate interruption is possible.
  •	Added test button "Test last sigp" for simple verification of created signatures.
  •	New switch: Automatically Clear LOG with Start button.
Info: 
  •	The AI tag stands for Application Improvement. Versions marked in this way only have a new application file (SafeNotes.exe), a new description of changes (History.rtf) and updated signature (VerifyInstall.sigp). Other changes are only if required by the new application and are all described in this history file (History.rtf).
  •	This AI is a fully functional version and is published on the web. Only various information files are not updated. This will speed up the release of new versions with interesting new features.

5.1.2
February 29, 2024
New features: 
  •	When you open a Backup file then the application AI(artificial intelligence) will help you to secure restore it.
  •	Opening a file at the cursor position or from selected text: Added detection of "http://" and "https://". Action is defined with the ".html" extension.
  •	Safe signature: If an existing signature file is used as input, then a sort of file names will be offered. This allows a high flexibility when using an input file that you create manually. Also, an FLIST file (*.flist) can be used as a file list.
Miscellaneous: 
  •	External language files have been updated (EN, SK) 
  •	Small text changes in different areas (menu items positions, added icons, etc)

If you have a personal license (Class-A), an upgrade from v5.0.7 or older will be prompted the registration password to activate the registration. If you have only Class-B license for one defined computer, created by app 5.0.7 or older, then you must use an identical version of application (and computer and OS) to activate this license. Needed app version you can download from a SafeNotes website in the download section under old versions. A signature file to verify all versions of SafeNotes is included in this installation to easily verify all install or zip files.

5.1.1
February 7, 2024
New features: 
  •	When you minimize the application, it will be locked. Needed password to unlock (can be enabled/disabled via Options).
  •	Added feature to search text in all open documents - a very powerful feature for users who use Safe Notes extensively with their documents
  •	Search AI logic was improved: The "wrap around" option is shown only if it has a logic. Switching tab/document will close the Search dialog.
  •	Safe signature: An existing signature file can be used as an input file for the file list (this makes it easy to recreate a new signature after some files have been changed)
  •	An improved algorithm for calculating password quality when entering unicode characters
  •	File info panel - added security info for saved SNF files (file security in bits)
  •	Not successfully decrypted documents have a different icon on the tabs. And special or read-only files also have different icons. The instant overview is greatly improved by this. 
  •	Options/Edit Configuration Files - added the ability to view/edit the "Open at Cursor" batch file
Miscellaneous: 
  •	The registration was opened for the year 2024. Limited, because it is dependent on donations and unfortunately the main sponsor of our ArtbyMind projects died due to the covid "pandemic" in January 2021. Please donate now, your 5 euros/dollars is a small value for you, but a big value for ArtbyMind.
  •	External language files have been updated (EN, SK, DE, CZ) 
  •	About/Security info - added new information
  •	Small text changes in different areas (menu, about, safe signature, encrypt tool, puzzle, options, pwd dialog)

March 21, 2023
New features: 
  •	See version 5.1.0 RC
  •	Added internal audio decoders: WAV, FLAC and APE
  •	After minimizing, Lock app (can be enabled/disabled via Options)
Miscellaneous: 
  •	The registration was opened for the year 2023. Limited, because it is dependent on donations and unfortunately the main sponsor of our ArtbyMind projects died due to the covid "pandemic" in January 2021. Please donate now, your 5 euros/dollars is a small value for you, but a big value for ArtbyMind.
  •	External language files have been updated (EN, SK) 
Info:
  •	Over the past twelve months, version 5.1.0 RC has been extensively and precisely tested.
  •	This is a normal version and is published on the web. The previous "Release Candidate" was only distributed to a special group of registered Safe Notes users.
  •	The supported audio file types are WAV, FLAC and APE. The use of the external universal-audio-library-package was removed. Direct support for WV, ALAC, AIFF, OGG, DFF, DSF and MP3 audio formats has been disabled. Unsupported files need to be converted to WAV/FLAC/APE with external application for detailed audio process in the signature tool. We cannot purchase an external license without a donation from users.
Planned: 
  •	Videos on how to use many of the features
  •	New encryption code for fast encryption of very large files and with full support for unicode file names. The write/verify will be handled in blocks and not for the whole document as with small/normal files. 

5.1.0 RC (not oficially published)
March 21, 2022
New features: 
  •	We are music lovers. With the new Safe Signatures tool, you can securely identify and verify your audio files for the first time in the history of music distribution.
  •	The encryption tool has a new dialog mode. You can set "Standard" or "Source to Target" mode, which is the equivalent of the file-copy function in the two panels file managers.
  •	File encryption can be used directly from TotalCommander via the included plugin. Highly recommended for TotalCmd users, this is a must-have TotalCmd security update. 
  •	Open the file at the cursor position or from the selected text. You can define any type of file to be opened (audio, video, text, image,...) using third-party applications (or your own). The settings are in the ini-file and the batch file.  
  •	Open a directory at the cursor position or from selected text using the explorer or third-party applications (e.g. file commanders).
  •	The plug-in encryption module (SCX) is now available for all users (in advanced user mode). You can use absolutely any encryption via the plugin. You can write your own encryption plugin and add it to the cascade.
  •	Various encryption plugins are included (CAMIND, ARC4, TLUC, TRND, DemoDUMMY) with source code, even with military grade encryption and 16384-bit keys.
  •	Improved the Request for License or for Certificate (Safe e-Messages)
  •	Creating automatically registration info documents
  •	New option settings for password dialog, also saving rtf/txt dialog only once
  •	After password dialog closing, hide stored password (can be enabled/disabled via Options)
  •	After minimizing, hide stored password (can be enabled/disabled via Options)
  •	Options/Open Settings File - added the ability to view/edit the "INI" file
Miscellaneous: 
  •	Changed password save dialog - default password for save is now the original password used for open (up to 5.0.9 default was the new password)
  •	The default copy from public files to clipboard is unencrypted (can be turned off in Options)
  •	The password dialog always shows advanced information (position, repeating), can be enabled/disabled with Options
  •	Find can search with wrap around
  •	New default automatic names for bookmarks and clipboard saving (derived from date and time)
  •	Bookmarks saved with cursor position. Ini files can also be loaded as a bookmark.  
  •	TrueCrypt container armor - This tool replaces the hidden undocumented encryption key stored in TC containers with random data (or restores the original contents). Only for real IT professionals! This tool is distributed from version 5.0.1 but used only by special group of users via special switch.
  •	The random salt when using the SCX plugin is reduced to 192 bits and the last 64 bits are the SCX ID.
  •	Advanced user mode is always allowed when SK language is selected (no free/personal registration key required). Also, the subkey is increased to 160-bit.
  •	The encryption tool use compression before encryption if it has an advantage 
  •	Save question for RTF/TXT is displayed only on the first save. Unchanged, a prompt is always displayed when the Save As option is used.
  •	New philosophy of security enhancement options (with puzzle). Also for registered if license is not maxed (via Options window). Purchased/donated license has no limit and can increase security everytime in unlimited steps, others only in one step.
Safe e-Messages (Safe Mail):
  •	The POSTOFFICE/e-Postman signature key, the Safe384VR is replaced with two new keys, P256k1 and BrainpoolP512r1. The changes were necessary to make Safe Signature compatible for verification with third party applications (e.g. OpenSSL, PGP/GPG)
  •	Public ECC keys are stored in e-Postman in compressed format and without unused parameters.
  •	The old POSTOFFICE/e-Postman are fully functional, but you need a new one to use the Safe Signature.
  •	Better navigation when changing the PostOFFICE password
  •	The verifiable random source for ECC256k1 and ECCSign has been changed from 4096-bit source to 512-bit source and the "Bitcoin" key derivation function ("Ultra-Safe" type) is used. This allows a clear and secure integration of the bitcoin wallet into POSTOFFICE. It also allows the association of PostOFFICE with a bitcoin address; with the maximum security key in PostOFFICE.
  •	The calculated BTC addresses and private keys are displayed in the PostOFFICE detail. Calculated BTC addresses and public keys are displayed in the postman (RAW) detail. The data is calculated from 256-bit koblitz ECC keys.
  •	RSA key generation - The Miller-Rabin test now uses 1024 rounds (previous versions used 80 rounds) with the OpenSSL library. The internal test has 80 rounds (previous versions used 54 internal rounds).
  •	The public exponent for over 2048-bit RSA has changed from 5AFE64B17C0D3299 to 5AFE64B17C0DE999, both 64-bit primes. Standard security uses a value of 65537 (17-bit).
  •	The prime number test for 64-bit versions is exact, for larger numbers is used the Miller-Rabin test with user-defined rounds (up to 524288).
  •	POSTOFFICE, e-Postman, e-Message always use compression and 6 root ciphers. Any external SCX cipher can be used as an added 7th cipher (this can be enabled/disabled with Options). Until version 5.0.9, the compression/encryption setting was used according to the Options setting. 
Safe Signatures:
  •	This is a new, amazing tool that can sign/verify any file or a whole group of files in an unlimited directory structure
  •	Has a special process for audio files. Can only sign/verify the included audio stream for known PCM/DSD audio formats with 32/24/16/1-bit (WAV, AIFF, MP3, OGG, FLAC, ALAC, APE, WV, DSF, DFF containers) with defined SNR sensitivities to detect gaps in the beginning and end of the music.
  •	You can use the new open standard "Safe Signature" with a human-readable format, for thousands of files in tree structures, with 8 different hashes, 3 independent signing keys, SafeNotes signature, 5 different audio hashes from the internal audio stream, smart CRC/hash calculated only from music data whose level is not zero or exceeds the defined noise level (-12dB to -96dB) also using adaptive auto-detected background noise.
  •	Signed files can be verified using third-party applications (OpenSSL, PGP, etc.) and also standard generated checksums (SHA256, MD5, etc.) can be verified by a third party.
  •	Paranoid Button: Files signed with the "Safe Signatures" tool can be verified using a third-party OpenSSL application immediately with an automatically generated batch file. This third party verification is similar to the verification in Bitcoin tools.
  •	You can also create an (in our opinion already obsolete) OpenSSL signature for only one file, with a human-unreadable format, without any information about the signer and keys used. Signed files can be verified using third-party application OpenSSL immediatly with button-click.
  •	You can verify files using their OpenSSL signatures. 
  •	The Signature Tool can also be used commercially with minimal restrictions, see the license text in the Safe Signatures form (Show more options|Show info about...).
Bug fixes:
  •	Public file with unknown extension when "Save as" without extension and with file filter [*.*] became .png extension - fixed.
  •	Postman import, when lines were modified when transferred via mail/clipboard, import was not possible - fixed (fixed by reformatting line spacing)
  •	Installer (setup v508 and v509) overwrites old configuration with default (INI file) - fixed.
Info:
  •	Distribution include the SCX Plugin for SafeNotes with military grade encryption CAMIND, with precise documented source code (password will come after the patent is published by the patent office)
  •	Source code and Crypto-Plus-Library are included in the installation, no separate download is required.
  •	All packages include a Safe Signature file for easy verification of installed files. 
  •	The SafeNotes plugin for TotalCommander for easy file encryption or sign/verify operation are included in the distribution.

  •	Steganography, hiding information inside the picture so thats it is impossible to detect this. It meets the strongest military standards. If you use a good cover photo, then can be used maximum security setup with automatic picture size reduction. Steganography uses its own encryption safe-key with 2240-bit, 6-ciphers cascade and 256-bit salt. This is independent from original safe-key. It is also possible to use a different password from the original password used to encrypt snf file (but it's paranoid:^).
  •	Wipe tool, this is a sensitive data destruction tool, for secure delete files or free space wipe from hard drive or memory keys. You can choose from five different algorithms, such as U.S. DoD 5220.22-M(E) or Gutmann method.

  •	First published version on the web
  •	Cryptographic functions as SHA1, RipeMD160, Tiger2, SHA256, RipeMD320, SHA512, PBKDF2, BCrypt, SafeCrypt are used for key creation. The number of iterations is 52224. Ciphers for encryption are AES(256), Blowfish(448), Twofish(256), IDEA(128), CAST6(256) and Serpent(256). They are used one after another in cascade with separate keys and initialization vectors. SafeNotes uses three independent keys, one for head, one for salt and one for data encryption. This will increase the need for keys to 6720-bit. Encryption far exceeds the strongest military standards. Data is packed before encryption.
