Macro Definition Documentation

◆ MAX_AES_KEY_LENGTH

#define MAX_AES_KEY_LENGTH 256

Maximum supported key length.

Function Documentation

◆ my_aes_create_key()

void my_aes_create_key	(	const unsigned char *	key,
		uint	key_length,
		uint8 *	rkey,
		enum my_aes_opmode	opmode
	)

Transforms an arbitrary long key into a fixed length AES key.

AES keys are of fixed length. This routine takes an arbitrary long key iterates over it in AES key length increment and XORs the bytes with the AES key buffer being prepared. The bytes from the last incomplete iteration are XORed to the start of the key until their depletion. Needed since crypto function routines expect a fixed length key.

Parameters

[in]	key	Key to use for real key creation
[in]	key_length	Length of the key
[out]	rkey	Real key (used by OpenSSL)
[out]	opmode	encryption mode
