You have my full permission to use any of these implementations in any commercial or non-commercial product royalty free. All algorithms are public domain. The RC4, IDEA and Skipjack algorithms may require permission from the patent holders for commercial use.

Disclaimer: All algorithms are provided as is without warranty of any kind. I will not be held responsible for illegal misuse of these algorithms. There are no known export restrictions for the above algorithms but if any apply and you are outside the United States then you are prohibited from using the restricted algorithms.

I have attempted to leave original credits left rendered but due to the fact that a couple of the algorithms have been claimed by 5 seperate authors I am unable to fully reference all original authors without lengthy investigation.
