VHDL implementation of the twofish cipher for 128,192 and 256 bit KEYs. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.

Aircrack-ng is an 802.11 WEP and WPA-PSK KEYs cracking program that can recover KEYs once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools. In fact, Aircrack-ng is a set of tools for auditing wireless networks.

A Public Key Infrastructure (PKI) binds cryptographic public KEYs to physical entities through digital certificates. A PKI includes components that issue digital certificates and distribute certificate status information. PKI users select one or more certificate issuers as trust anchors, and establish security services based on certificates that may be validated using one of their trust anchors.

The MC68HC05K0 is a low cost, low pin countsingle chip microcomputer with 504 bytes of userROM and 32 bytes of RAM. The MC68HC05K0 isa member of the 68HC05K series of devices whichare available in 16-pin DIL or SOIC packages.It uses the same CPU as the other devices in the68HC05 family and has the same instructions andregisters. Additionally, the device has a 15-stagemulti-function timer and 10 general purposebi-directional I/0 lines. A mask option is availablefor software programmable pull-downs on all ofthe I/O pins and four of the pins are capable ofgenerating interrupts.The device is ideally suited for remote-controlkeyboard applications because the pull-downs andthe interrupt drivers on the port pins allowkeyboards to be built without any externalcomponents except the KEYs themselves. There isno need for external pull-up or pull-down resistors,or diodes for wired-OR interrupts, as these featuresare already designed into the device.

PrintNow is a 32-bit application that runs only under Windows 95 or Windows NT 4.0. It allows your PrtScr and Alt+PrtScr KEYs to print a screen capture directly to your printer instead of just copying the image to the Windows clipboard. PrintNow can also print any DIB image in the clipboard, regardless of its original source. PrintNow supports multiple instances, it can print multiple copies of a screen capture to the same printer with different print settings, to several different printers, or any combination thereof, with a single KEYstroke.
