AVRC4

typedef struct AVRC4 AVRC4

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/rc4.h>

Функции

av_rc4_alloc()

AVRC4* av_rc4_alloc

(

void

)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/rc4.h>

Allocate an AVRC4 context.

av_rc4_init()

int av_rc4_init	(	struct AVRC4 *	d,
		const uint8_t *	key,
		int	key_bits,
		int	decrypt
	)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/rc4.h>

Initializes an AVRC4 context.

Аргументы

key_bits	must be a multiple of 8
decrypt	0 for encryption, 1 for decryption, currently has no effect

Возвращает

zero on success, negative value otherwise

av_rc4_crypt()

void av_rc4_crypt	(	struct AVRC4 *	d,
		uint8_t *	dst,
		const uint8_t *	src,
		int	count,
		uint8_t *	iv,
		int	decrypt
	)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/rc4.h>

Encrypts / decrypts using the RC4 algorithm.

Аргументы

count	number of bytes
dst	destination array, can be equal to src
src	source array, can be equal to dst, may be NULL
iv	not (yet) used for RC4, should be NULL
decrypt	0 for encryption, 1 for decryption, not (yet) used
