av_camellia_alloc()

struct AVCAMELLIA * av_camellia_alloc

(

void

)

Allocate an AVCAMELLIA context To free the struct: av_free(ptr)

av_camellia_init()

int av_camellia_init	(	struct AVCAMELLIA *	ctx,
		const uint8_t *	key,
		int	key_bits
	)

Initialize an AVCAMELLIA context.

Parameters

ctx	an AVCAMELLIA context
key	a key of 16, 24, 32 bytes used for encryption/decryption
key_bits	number of keybits: possible are 128, 192, 256

av_camellia_crypt()

void av_camellia_crypt	(	struct AVCAMELLIA *	ctx,
		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

ctx	an AVCAMELLIA 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, NULL for ECB mode
decrypt	0 for encryption, 1 for decryption
