Drag'n'Crypt ULTRA is a small file encryption tool that uses a handy "drop box" interface to make encryption and decryption fast and easy. Uses the Twofish encryption algorithm

Note:

  • File size is limited. Maximum file size depends on 1/2 free memory (for example: with a RAM of 512 MB RAM you can encrypt a 256 MB file). The author recommends TrueCrypt for larger files.
  • The website is in German, but the program is in English.
  • Starting from version 2.2.0, Drag'n'Crypt ULTRA is no longer backwards-compatible with data encrypted using Blowfish or TEA.

The website of Drag'n'Crypt has a grim notice posted:

Drag'n'Crypt ULTRA is history.
The further development of the program, sales and support will officially be discontinued on August 1st, 2020. Inquiries are no longer answered. DCU is no longer available for download.
Other sites that host DCU are also asked not to offer the program for download anymore and to delete the listing.
Switching to a different encryption software, which is currently still being used, is urgently indicated, as permanent program maintenance is important for security reasons.
I would like to thank everyone who accompanied and supported me in the development of DCU. It was an exciting time.

@New_Order: Anyone who can write encryption software has my respect. Anyone who offers their software for use by others at no cost has my thanks - Vielen dank!

The testing I was doing on DCU was to investigate Ganamyde's problem of complete computer lock-down when encrypting large files. Even though I tried encrypting files that were probably 100x bigger than DCU was intended to work with, I did not get lock-down. This is good because it shows that DCU can encrypt large files.

About half way through encrypting a 1GB file, I noticed that DCU was trying to trying to connect to the internet, and I blocked it. I was not expecting DCU to connect to the internet at all, and it seemed strange that it tried to do this while it was still encrypting a file. Unfortunately for you I am very sensitive to software that does the unexpected, and 2x as sensitive when the software is processing data that the user believes should be kept secure. That is why I marked DCU down.

I am now wondering if the internet connection could be the cause of Ganamyde's problem. I am guessing that you start a new thread to check for a new version of DCU. If the internet connection has to wait for data, that could cause the thread to lock up. This is not much of a problem with multiple processor cores, but if Ganamyde's computer was old enough to only have a single core it could cause his lock-down. Of course this is complete guesswork from me and is very likely wrong.

Thank you all for trying DCU.
DCU is concepted to encrypt smaller files. If you need to encrypt huge Files is Truecrypt the better solution. But if you need a program to protect your smaller files (your Documents and Pictures) and you need to use a 100% portable application than is DCU your tool.

The rule for the max. possible filesize is your RAM / 2 (for example your RAM is 4GB you can encrypt a file with max. 2GB size).

@Craunch: DCU do only using a connection to internet if you checking for newer Version, if you want to contact me, if you want visit the DCU Website / DCU at Facebook. DCU do not connect to internet if you encrypt or decrypt a file!!! DCU do not send any kind of informations back to me!!!

In the near future i plan to release DCU as Open Source. So everyone can take a look to the Source Code.
It's your decide to work with the program. But think about: DCU is 100% non commercial. I spend a lot of time for this project. You must not like/use DCU but please respect my work. And please excuse my bad english.

You're welcome.

I downvoted this program because of its unexpected attempt to connect to the internet while encrypting - I don't trust security software that does things that I don't expect and for which there appears to be no explanation.

Craunch: thanks for testing, I hadn't used this program on anything larger than a few megs
