New language files es, fr, it, nl, ru, uk (Windows app and *_decrypt.cmd). de.ini: wrong language name, merged lines, shortened subtitles. gui.cs: the subtitle no longer runs under the tab bar or the language button (it shrinks, then is cut with ...). Browser page: same nine languages as the Windows app, the saved language choice is kept, decimal comma outside English. SecureEncrypt.cmd and web/index.html rebuild.
v8 Changelog: SecureEncrypt is a free, open-source AES-256 file and folder encryption tool developed for Windows 7–11. It creates self-decrypting files, meaning the recipient does not need to install any software. It offers cross-platform compatibility via Chromium-based browsers (with support for Linux, macOS, Android, and iOS) and is capable of handling large files. Large file mode in the browser version: in browsers that support the File System Access API (Chrome, Edge, Opera, Samsung Internet) the 1.5 GB limit is gone. Data is processed piece by piece (4 MiB) and written straight to disk, so memory is not a limit. You choose the file to save when encrypting and the target folder when decrypting. There is a progress bar and a Cancel button; work with a password takes two steps (reading/checking, then encrypting/decrypting). The result is an ordinary SEv2 file. Tested with 2.6 GB and 5.65 GB (desktop) and 2.33 GB (Android, Chrome and Samsung Internet; folders included). Firefox and Safari do not have this feature, so the 1.5 GB limit applies there. Password optional for large files: without a password and key file the content is only hidden, as in the Windows version (mode 1, no security); an amber warning is shown in the result. No-password files are compatible with Windows in both directions. Large file decrypting: files are written straight into the chosen folder (with the archive's sub folders) without creating a new sub folder; an existing file is never overwritten, a number such as " (2)" is added to the new file's name; on a cancel or an error the files this run created are removed. The empty "written to the folder" line is no longer shown when a drive root is chosen. Faster SHA-256/HMAC in the browser: about 1.6x (~105 → ~165 MB/s) with all 64 rounds written out. The code is generated by srcbuild.ps1. Faster AES on Windows: the fast provider (AesCryptoServiceProvider, via SymmetricAlgorithm.Create("AES")) replaces RijndaelManaged; it falls back to the old one if missing. 600 MB: encrypt 15.3 → 6.3 s, decrypt 14.6 → 4.8 s. The output format is the same. Coloured result messages: in the result window WARNING lines are amber and error lines red (independent of the language). Web language files split out: the texts of the browser version moved to src\web\web_lang*.ini (tr, en, de, es, fr, it, nl, ru, uk); the build embeds them all into the page, missing keys fall back to English and the build warns. Version number: the title of the "About" window now shows the version ("SecureEncrypt v8.0 - About"). The number comes only from $Version in srcengine.ps1; build.ps1 passes it to the window code. Compatibility: the file format (SEv2) did not change. _decrypt.cmd files created with v6/v7 open in v8 (Windows and browser) and v8 files open with the older decryptors (tested in both directions). Previously created _decrypt.cmd files carry their own decryptor, so they keep working but do not get the new speed-ups. On Windows 7 / PowerShell 2.0 both the Windows app and the browser version were tested (with the fast AES provider) and work without problems; the old AES provider is used if the fast one is missing.
v8.1 A bug-fix release; no new features, and the file format (SEv2) did not change. The old encrypted file is no longer deleted early: when a of the same name already existed, encrypting again deleted the old file at the start; if the run was interrupted or failed, no copy was left. The old file is now replaced only after the new one has been written completely. _decrypt.cmd "Delete originals" removes only what was archived: deleting is now limited to the files that really went into the encrypted copy. Files added to a folder or changed after they were read (different size or modification time) are kept and listed with an amber warning; folders are removed only when they end up empty. Previously the whole folder was deleted, so files missing from the encrypted copy could be lost too. Dragging and dropping files with & in the name: Explorer does not quote a dropped path that has no spaces; when a file or folder with in its name was dropped onto , the name was split and the part after the could be run as a command. Dropped paths are now read from the command line itself and the script closes before the remaining part can run. The launcher of the generated files did not change in this release. &SecureEncrypt.cmd&_decrypt.cmd "Decrypt" in the new Windows 11 context menu: the menu helper now starts the file with the system's . The installation has to be repeated for this to take effect (Uninstall, then Install). _decrypt.cmdcmd.exe Browser version, freeze with large files: with a large file (seen with 4.39 GB) the page did not respond during the first seconds after the start; the progress bar did not update and the buttons could not be clicked. The work now hands control back to the browser at regular intervals; progress is visible from the start and the Cancel button works. Browser version, choosing the file to decrypt: on desktop browsers the file dialog lists files only ("All files" can still be chosen). No filter is applied on phones and tablets. .cmd Language files: the key for the kept-files warning was added to all nine languages. del_kept
