Hi,
Here is my implementation of Rijndael for mono. It only supports ECB
mode and zero padding just now. I think the implementation of the other
chaining modes can be shared with the other symmetric ciphers. The
patch also includes fixes for SymmetricAlgorithm to make it treat key
sizes properly in bits.
But! It only works under mint just now because of bug #29365. So, I've
not included my test case in the patch because it will just fail under
the jit. I've included a seperate test program (RijndaelMain.cs) if
someone else wants to test it (or use it as a test case for checking a
fix for #29365). The test program runs three of the test vectors from
the FIPS standard.
I don't know whether to commit this to CVS just now, or whether to wait
until the jit bug is fixed and I can add my test case too.
