Logan007	0ff7eac6fc	made openssl_err_as_string static to avoid conflicts with other ciphers that would also use their own function - those can't rely on the AES module being there	5 years ago

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: ???

emanuele-f	50bc1492e2	Remove unnecessary structures in AES encryption This undoes most of the changes made in 37233553a4 as the problem with the drops was only mitigated. The actual fix for the dropped packets was in e989f475a1 and the invalid initialization was the root cause	6 years ago
emanuele-f	e989f475a1	Fix invalid initializations	6 years ago
emanuele-f	c71f629d1b	Fix encryption key being zeroed by AES initialization	6 years ago
emanuele-f	37233553a4	Fixes packet drops while communicating with multiple nodes in AES PSK Per-node AES structures must be kept as CBC cannot work with a single structure across multiple nodes	6 years ago
Luca	dcf96a0809	Added #ifdef's for AES	6 years ago
emanuele-f	e4601590aa	Add -A option to enable AES CBC psk encryption	6 years ago
Luca Deri	7b07636281	Refreshed copyright and added contributors list	7 years ago
Luca Deri	b1e9ce6d2a	Initial SVN import of n2n v2	8 years ago
