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
