Suggestions - permissions, timestamps, and source file naming
by Andy Schofield 23 Jan '11

23 Jan '11

Hi Paul Just discovered aescrypt. It seems to be exactly what I am looking for - a file en/decrypter which is open source and works on linux, osx and windows. Thanks very much for creating this. I've been adapting it to create an rpm (for redhat style linux distributions) and had a couple of suggestions/observations for it: (1) File permissions I notice that the .aes file created by encryption under linux seems to take whatever umask would give it. That may be the preferred solution - I genuinely do not know - but I would suggest that the .aes file should inherit the permissions of the file it is created from. Presumably the same should apply on decrypting. (2) Time stamps On that subject, the encrypted version of the file, could perhaps have the same creation/modification time as the original. It could then also pass that back when it is decrypted. (3) Name and contents of the source file It might be helpful (for packagers etc) if the linux source file adopted a more standard naming convention, and also included the man page which it also put in place. At present the source file is: aescrypt305_source.tar.gz I would suggest: aescrypt-3.0.5.tar.gz which then tar unzips to aescrypt-3.0.5/ These are all very minor points for an already good and useful piece of software. Again - thanks for creating this. Andy

Created a discussion forum for AES Crypt
by Paul E. Jones 29 Nov '10

Folks, Since the mailing list sees little activity, I thought about getting rid of the mailing list and just having a discussion forum. I'm not sure if that will get more traction, but it's worth a shot :-) The forum is here: http://forums.packetizer.com/viewforum.php?f=72 There is a link from the AES Crypt page. I'll leave the mailing list up for a little while, but I might close the list if there isn't much activity. Or, we could turn it into a developer list. Thoughts? Paul

Re: [aescrypt] Support Inquiry

There are no instructions, really. The core is written in C and the GUI part is a trivial AppleScript script. We've heard of some folks having issues, but there are no consistently reported problems. Are you getting any kind of error message?

Updates to AES Crypt for Windows
by Paul E. Jones 28 Nov '09

28 Nov '09

Folks, Over the weekend, I updated the AES Crypt code for windows. I did several things: . Created a native Windows console application that is not dependent on cygwin (this is just a modified version of the Linux code) . Updated the icons used in all version . Included the console application with both the 32-bit and 64-bit builds . Corrected the installation directory used in the 64-bit version posted previously (the 64-bit code was installing in the 32-bit directory) . Revised the version number to be 3.06 As a part of the revision to the icon, I tried (without success) to implement context-menu icon that is transparent. Apparently, I did not properly create device contexts, perform a TransparentBlt() correctly, or something: all I got was a black square. So, the icon is left as a bitmap as before with a white background. If you of you know how to improve this, I'd welcome the input :-) Paul PS - I only tested the new console application just a little. It did seem to encode and decode both text and binary files properly, but I will not swear that it's entirely error-free. If you wish to tinker with it, by all means do. All of the source code is online.

Hi, It was easy to spot the bug and fix it. The problem was related to the way the last block size was computed. Other changes I've also made: - Added a test suite to make sure AESCrypt.java works as expected. - Fixed a bug when reading the HMAC of an empty payload. - Make sure the "AES" header is correctly encoded. - Some typos in messages and documentation. Paul, would you please publish the new version on the web?

That should definitely not happen. The fact it is an XLS file should also make no difference at all. Perhaps there is a bug with either reading or writing the file modulo? David, would you be able to provide some guidance?

赵鲁, I am forwarding your message to the AES Crypt mailing list to see if others might be able to help you. However, it's not entirely clear what the issue is, so can you clarify it further?
