emanuele-f	bb07f0426e	Properly initialize AES IV and hash the AES key This implements the changes discussed in #68 and #72. This breaks compatibility with the previous AES implementation. This also fixes two problems reported by valgrind: ==4887== Invalid write of size 2 ==4887== at 0x483E9DB: memmove (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==4887== by 0x10E37F: setup_aes_key (transform_aes.c:378) ==4887== by 0x10E451: add_aes_key (transform_aes.c:401) ==4887== by 0x10ED10: transop_aes_setup_psk (transform_aes.c:580) ==4887== by 0x10A547: main (benchmark.c:92) ==4887== Address 0x4d574a0 is 0 bytes after a block of size 16 alloc'd ==4887== at 0x4839B65: calloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==4887== by 0x10E337: setup_aes_key (transform_aes.c:374) ==4887== by 0x10E451: add_aes_key (transform_aes.c:401) ==4887== by 0x10ED10: transop_aes_setup_psk (transform_aes.c:580) ==4887== by 0x10A547: main (benchmark.c:92) ==13057== Use of uninitialised value of size 8 ==13057== at 0x49023B3: ???
