void av_aes_crypt ( struct AVAES a,
uint8_t dst,
const uint8_t src,
int  count,
uint8_t iv,
int  decrypt 
)

Encrypt or decrypt a buffer using a previously initialized context.

Parameters:
count number of 16 byte blocks
dst destination array, can be equal to src
src source array, can be equal to dst
iv initialization vector for CBC mode, if NULL then ECB will be used
decrypt 0 for encryption, 1 for decryption
