dotNet Disk Imager
Lightweight RAW and ZIP disk images reader and writer to USB or SD
IMPORTANT!!! Since this is new software, your web browser, operating system or even possibly antivirus software may report security alerts against this tool. Please ignore that messages until this tool gets widely spread. This program is highly inspired by Win32 Disk Imager and sort of copies it's function. However, I've added some features, like verification of readed/writed image file and the most important is on the fly support for zipped images. Another features worth mentioning are simultaneous write to multiple devices at one time or wiping of device filesystem and partitions. I would be happy to hear your feedback and I'm ready to listen to your suggestions. Feel free to request new features, if I found them interesting I will definitely implement them. Requires .NET Framework 4.6.1 (download here: http://go.microsoft.com/fwlink/?LinkId=671729 ) Supports Windows 7 and newer. If you need older Windows support, use Win32 Disk Imager. Please write a review. -

A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.
