WinTrezur protects digital photos and images by encrypting them into safe archives (A2R files) with a password. WinTrezur operations are accessible via toolbar, main menu, or context menus. To access the main menu via keyboard press Atl+M. Pressing Alt+X on any window closes the application.
To create a new encrypted archive (*.a2r file), select the files and folders you want to add to the archive file and click the [New] button from toolbar, or select [Create Archive] from context or [Security] menu. Additional files and folders can be added directly in the [Create Archive] window that shows up, using its toolbar or context menu (new files / folders can be appended also after archive creation).
[Creating an encrypted archive]
Click the [Start] button to create the new archive file. Archive options window will be shown to change or confirm the default options. Change the name and path of the new archive file to be created, or accept the default one.
Once the archive options are confirmed (by clicking [OK] button), the [Password] window will appear. Enter a password for the new archive, and optionally change the encryption settings (you have to remember your changes!). The key buttons next to password fields contain additional password-related options that can be occasionally handy, such as, a mouse-based keyboard to avoid key loggers. Confirm the password by clicking [OK] button, and the new archive will be created, reporting progress as files are added (for extra security, files are added in random order to the archive). Any ordered combination of existing files, such as, some of your mp3 music files, or images, can also be used as password.
If you forget your password or encryption settings you used then there is no way to recover back your encrypted data. To be sure, reopen once the encrypted files after encrypting them, just in case, to make sure the password you enter is same as you think.
[Browsing encrypted archives]
WinTrezur instance remembers (encrypted) the password of the newly created archive (as long as it runs in RAM). Go to the archive to browse its folder and file contents. Encrypted image files within archives are directly previewed inside WinTrezur without creating any temporary disk files. You can view thumbnails, slideshows, rotate and zoom images, apply effects, view images fullscreen, view Exif properties, and more.
[Maximized image preview with mouse hover buttons shown]
Double-click on an image file to maximize image preview (or use F6, or Space key). To quick zoom-in an image (fit to preview), click and hold pressed the left mouse button. Moving the mouse, while left mouse button is pressed, moves the zoomed image. On maximized image view, move the mouse on bottom / top right part of the windows to quickly access additional options. The mouse wheel or cursor keys can be used to move to previous / next file. Space key moves also to next file. Ctrl + mouse wheel increases / decreases current image zoom.
[Viewing encrypted videos]
To open other types of files, double-click on them, or choose [Open] from file's context menu. Text files can be open with the internal text viewer. Alternatively, other types of files, such as video files, can be open with default system associated application, or with any other installed application of choice. The selected file, is then decrypted in a temporary folder (by default, with a randomized name - you can change this at the options) and it is opened in the selected application. The temporary created files (for non-image and non-text file types) are safely wiped automatically when you close the application, or they can be wiped explicitly at any time by using [Security / Wipe / Temporary Files] menu (if that menu is not active, there are no temporary files). Hint: Pressing [Enter] key also opens the [Open] window for non-image files. Pressing [Enter] key on the [Open] window, runs the file with last settings. Like this, a series of movie files can be open / run by using twice [Enter] key on each of them (and using the left cursor arrow key to move to the next one).
When the current application instance is closed, all entered password are forgotten, and will ask again next time to provide the password when browsing an encrypted archive file.
[Saving encryption settings]
If the default encryption settings were changed in password window when the archive was created, then apart of password, all changed options must be set correctly in order to properly open the archive file! The encryption settings are not saved in any form inside the encrypted files for security reasons. It is impossible to identify WinTrezur encrypted files as such ones in some way. You can save and load encryption settings on your own in separate files using the toolbar [Manager] and [Export / Import] buttons. The encryption settings should normally not be treated as a secret, but this is up to you to decide.
[Sharing encrypted archive passwords]
If several archives share same password (and encryption settings), then it is very convenient to check [Share A2R Passwords] option in the password menu in toolbar. When that option is checked, each unique password (and its related encryption options) needs to be specified only once per application instance. WinTrezur will then open all archives sharing same password (and encryption settings) when they are browsed.
[Modifying encrypted archives]
Archives can be edited at any time. Add new files using [Append Files] context menu, or drag & drop disk files to an open archive. To extract files, use the [Copy To / Folder] context menu, or drag & drop archive entries to a disk folder within the application. To change the password, use [Copy To / New Archive] to copy selected file and folders to a new archive with a new (or same) password (or drag & drop to a another open archive). Move the archive file entries between archive folders (drag & drop within the archive) and rename them using [Move To] and [Rename] context menus. Contents of folders with same name are merged. Archive file entries can also be moved to a Trash folder, or deleted permanently using the [Delete] context menu - same menu can be used to irrecoverably wipe disk files and folders.
[Copy to USB]
WinTrezur is portable and you can copy it to a USB memory stick, using [File / Copy Application to USB] menu. Same menu can be used to update an existing USB copy, with a newer installed desktop version. Specify an USB disk folder where to copy the application.
When WinTrezur is closed, no one can view encrypted files or learn anything about them, unless they know the original passwords used to encrypt the archive files. Use WinTrezur only on trusted and uncompromised machines. For extra safety, it is recommended you disable page-file and hibernation for your system. To make sure Wintrezur download file is not corrupted verify its MD5 checksum. WinTrezur also lists the current EXE checksum (this is different from the downloaded package one) in [Help / About] menu if you click on the [I(nfo)] button. You may copy and store that value somewhere to use as reference later on if you want to make sure WinTrezur EXE is not changed.
