Original library taken from:
This distribution contains a bunch of libraries and example applications that I have made for Arduino, covering a variety of tasks from blinking LED's to LCD's and RTC-based alarm clocks. They are distributed under the terms of the MIT license.
The documentation contains more information on the libraries and examples.
If you are looking for my cryptography libraries for Arduino, then they can be found here.
For more information on these libraries, to report bugs, or to suggest improvements, please contact the author Rhys Weatherley via email.
