Con Kolivas e1af8fb0c0 Remove unused functions from aes.c and sha4.c 2011-03-16 00:51:28 +11:00
Con Kolivas 5da0633893 aes_crypt_cbc will allow you to work on the same buffer, so don't bother allocating a separate buffer. 
Allocate slightly more on the buffer that might be used for encryption rather than reallocing.
