Macro Definition Documentation

#define WAGE_STATE_SIZE   37

Size of the WAGE state in bytes.

The state is 259 bits, divided into 37 7-bit components, one per byte.

Function Documentation

void wage_absorb	(	unsigned char	s[WAGE_STATE_SIZE],
		const unsigned char	data[8]
	)

Absorbs 8 bytes into the WAGE state.

Parameters

s	The WAGE state to be permuted.
data	The data to be absorbed.

void wage_absorb_key	(	unsigned char	s[WAGE_STATE_SIZE],
		const unsigned char *	key
	)

Absorbs 16 key bytes into the WAGE state.

Parameters

s	The WAGE state to be permuted.
key	Points to the key data to be absorbed.

void wage_extract_tag	(	const unsigned char	s[WAGE_STATE_SIZE],
		unsigned char	tag[16]
	)

Extracts the 128-bit authentication tag from the WAGE state.

Parameters

s	The WAGE state to extract the tag from.
tag	Points to the buffer to receive the extracted tag.

void wage_get_rate	(	const unsigned char	s[WAGE_STATE_SIZE],
		unsigned char	data[8]
	)

Gets the 8 bytes of the rate from the WAGE state.

Parameters

s	The WAGE state to get the bytes from.
data	Points to the buffer to receive the extracted bytes.

void wage_init	(	unsigned char	s[WAGE_STATE_SIZE],
		const unsigned char *	key,
		const unsigned char *	nonce
	)

Initializes the WAGE state with a key and nonce.

Parameters

s	The WAGE state to be initialized.
key	Points to the 128-bit key.
nonce	Points to the 128-bit nonce.

void wage_permute

(

unsigned char

s[WAGE_STATE_SIZE]

)

Permutes the WAGE state.

Parameters

s	The WAGE state to be permuted.

void wage_set_rate	(	unsigned char	s[WAGE_STATE_SIZE],
		const unsigned char	data[8]
	)

Sets the 8 bytes of the rate in the WAGE state.

Parameters

s	The WAGE state to set the rate in.
data	Points to the bytes to set into the rate.
