-
- As the above disclaimer notes, you are free to use this code however you
- want. However, I would request that you send me an email
- (fritz /at/ cs /dot/ ucsd /dot/ edu) to say hi if you find this code useful
- or instructional. Seeing that people are using the code acts as
- encouragement for me to continue development. If you *really* want to thank
- me you can buy the book I wrote with Thomas Powell, _JavaScript:
- _The_Complete_Reference_ :)
-
- This code is an UNOPTIMIZED REFERENCE implementation of Rijndael.
- If there is sufficient interest I can write an optimized (word-based,
- table-driven) version, although you might want to consider using a
- compiled language if speed is critical to your application. As it stands,
- one run of the monte carlo test (10,000 encryptions) can take up to
- several minutes, depending upon your processor. You shouldn't expect more
- than a few kilobytes per second in throughput.
-
- Also note that there is very little error checking in these functions.
- Doing proper error checking is always a good idea, but the ideal
- implementation (using the instanceof operator and exceptions) requires
- IE5+/NS6+, and I've chosen to implement this code so that it is compatible
- with IE4/NS4.
-
- And finally, because JavaScript doesn't have an explicit byte/char data
- type (although JavaScript 2.0 most likely will), when I refer to "byte"
- in this code I generally mean "32 bit integer with value in the interval
- [0,255]" which I treat as a byte.
-
- See http://www-cse.ucsd.edu/~fritz/rijndael.html for more documentation
- of the (very simple) API provided by this code.
