av_aes_init()

int av_aes_init	(	struct AVAES *	a,
		const uint8_t *	key,
		int	key_bits,
		int	decrypt
	)

av_aes_crypt()

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

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