fz_aes_crypt_cbc()

void fz_aes_crypt_cbc	(	fz_aes *	ctx,
		int	mode,
		size_t	length,
		unsigned char	iv[16],
		const unsigned char *	input,
		unsigned char *	output )

AES block processing. Encrypts or Decrypts (according to mode, which must match what was initially set up) length bytes (which must be a multiple of 16), using (and modifying) the insertion vector iv, reading from input, and writing to output.

Never throws an exception.

fz_aes_setkey_dec()

int fz_aes_setkey_dec	(	fz_aes *	ctx,
		const unsigned char *	key,
		int	keysize )

AES decryption initialization. Fills in the supplied context and prepares for decryption using the given key.

Returns non-zero for error (key size other than 128/192/256).

Never throws an exception.

fz_aes_setkey_enc()

int fz_aes_setkey_enc	(	fz_aes *	ctx,
		const unsigned char *	key,
		int	keysize )

AES encryption initialization. Fills in the supplied context and prepares for encryption using the given key.

Returns non-zero for error (key size other than 128/192/256).

Never throws an exception.

fz_arc4_encrypt()

void fz_arc4_encrypt	(	fz_arc4 *	state,
		unsigned char *	dest,
