WebAfter I copied the code from aes_ctr.c and modified the AES_ctr128_inc to remove the L_ENDIAN code, things seem to work as expected now. Can somebody comment on why this is? I saw some discussion on the openssl-dev list back in 2003. Is there no standard on where the counter should reside? If it is different for different libs, how do libs ...
