Functions

func Lyra2

func Lyra2(
	k []byte,
	pwd []byte,
	salt []byte,
	timeCost uint64,
	nRows int,
	nCols int,
)

lyra2 Executes Lyra2 based on the G function from Blake2b. This version supports salts and passwords whose combined length is smaller than the size of the memory matrix, (i.e., (nRows x nCols x b) bits, where "b" is the underlying sponge's bitrate). In this implementation, the "basil" is composed by all integer parameters (treated as type "unsigned int") in the order they are provided, plus the value of nCols, (i.e., basil = kLen || pwdlen || saltlen || timeCost || nRows || nCols).

@param K The derived key to be output by the algorithm @param pwd User password @param salt Salt @param timeCost Parameter to determine the processing time (T) @param nRows Number or rows of the memory matrix (R) @param nCols Number of columns of the memory matrix (C)

func Sum

func Sum(data []byte) ([]byte, error)

Sum returns the result of Lyra2re hash.
