Hello,
I have attached a patch with optimization for twofish. Please let me know
if any further changes required.
Following are the results for crypto_bench after optimization.

Hello,
I have added the necessary functions for twofish in crypto_bench.
A note, there is no twofish implementation in openssl library but since the
code demands that all the libraries have the impl, i have introduced a
dummy function. Please let me know if anything has to be changed.
Thanks,

I have tried without y[] array.
Hello,
I have attached a patch to optimize the camellia block cipher.
I ran crypto_bench on the optimized version. Here are the results of
runtime using crypto_bench.

Hello,
I have made all the changes as suggested. If the number of if-else loops in
init() seem to be too many, please let me know I will change it but I have
put them to handle the return values and overflow issues. If there are any
other changes, please let me know.
