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 @paran iv initialization vector for CBC mode, NULL for ECB mode
decrypt	0 for encryption, 1 for decryption
