Perhaps the most significant update is the ability to select the cipher mode (the default was CBC). The most obvious update to the Windows build is the GUI is now GTK+3 instead of GTK+2, the other major change for Windows is the use of the latest version of libgcrypt (now inline with GNU/Linux and OS X). Speaking of OS X, I think that the libgcrypt issue there has been fixed. (encrypt still works if I remove libgcrypt from Homebrew - if you are an OS X user please let us know.) Next is Android: there were a few bugs that were found and have been now squashed. Specifically the keyboard would disappear when a user tried to enter a number in the password field. encrypt on Android, has too had an update to the version of the gnu-crypto library it depends on. This was prompted by the way that the CTR mode was broken, and didn’t allow an IV to be set (and version 2.1.0 does). Lastly, there were numerous memory leaks plugged, and greater/better use of the rc file: changing the selected algorithms/mode will be remembered for the next use (settings take effect immediately). Windows has better Explorer integration, and there has been work towards a similar level of integration on GNU/Linux (but it’s still a work in progress). encrypt - 2013.11.01 25th Jan 2014 -------------------- Update/Fix for libgcrypt version 1.6 encrypt - 2013.11 24th Nov 2013 ----------------- A significant bug in regards to the encryption of directories on Windows has been fixed with the help of Mark Condic, so much thanks there! There has also been several significant changes on all platforms such as the more traditional (or expected) approach to file links: on Unix-like systems the links themselves are stored by default (unlike before, where the files the links pointed to were stored); and on Windows and Android, obviously they don’t have links to encrypt, but during decryption links are handled in one of two ways: symbolic links are ignored, whereas hard links cause the file to be copied. Although this means the file is dupl- icated it’s the closest approximation to the original as possible. The second major addition to encrypt’s abilities is the option to create encrypted archives for previous versions of the application. NB This has had only limited testing and should’t be relied upon! You should really be using the latest version wherever possible! (But it’s there for those who might find it useful from time-to-time.) encrypt - 2013.02 7th Feb 2013 ----------------- Hot off the heals of our last release we’re here with another. It brings the much needed and hugely requested new feature: encrypted directories. You can now select and encrypt directories in addition to files. The has resulted in an update to the user interface to show the current progress and overall progress of the encryption/decryption. The other significant update is for Android version: key file support is now available. Use the menu to toggle between entering a password or se- lecting a file to for key generation. There has also been a couple of changes to the internal structure of the encrypted files; though as always, the latest version is able to decrypt your previously encrypted data. The native OS X port is now here too! So that’s now GNU/Linux, Microsoft Windows, Android and of course Apple’s OS X! encrypt - 2012.11 19th Nov 2012 ----------------- A little over a year since the previous release but we’re back with many significant changes: first and foremost is the capability to compress a file (or data stream) before it is encrypted. Before you ask, yes we’re intending to support encrypting multiple files in an upcoming (maybe the next) version. The other major improvement is the ability to set default algorithms for both the key hashing and encryption itself. On Unix-like systems create the file ~/.encryptrc or copy the example from utils/_encryptrc. If you are running MS Windows, the file is %Program Files%\encrypt\_encryptrc. The UI of the desktop edition has also been simplified; the output file is selected as you would expect, instead of having to select a directory and then type in the file name. In addition, there is a new menu option "Options". Currently the only option is to toggle compression on or off. encrypt - 201110 16th October 2011 ----------------- We’re on some sort of a roll here; there’s a new release of encrypt. It fixes a couple of minor bugs---checksums are now correctly computed and, therefore, correctly verified upon decryption---as well as introducing a few new behind-the-scenes features: the internal structure of encrypted data is split into blocks, which will be necessary in the future, as we introduce data compression (planned for the next release). The other new feature is the ability to notify the user if a newer version of encrypt is available for download. That’s all for now, although we’ll be back soon with more updates, such as compression, and anything else that comes our way... encrypt - 201108 21st August 2011 ----------------- It’s been a little while but here we have the latest offering for personal file security! In an effort to make encrypt even more useful to even more people, it’s been rewritten to use a 3rd party encryption library---notably, the GNU Project’s libgcrypt and gnu-crypto. This change increases the choice of algorithms as well as providing a base for an Android counterpart to the standard desktop package. That’s right---we’ve an Android version which is compatible with the desktop version. The inspiration behind providing an Android app came ( in part ) due to some of the security concerns which have been highlighted with services such as Dropbox. Whilst online file hosting services are a great way for transferring files from desktop to laptop, and now to smartphone or tablet, their less-than-ideal encryption processes meant something more was needed: encrypt for GNU/Linux, MS Windows and Android!
