Expand description

Generic PMAC instance

LC_SIZE regulates size of pre-computed table used in PMAC computation. With LC_SIZE = 20 and for 128-bit block cipher the table is sufficient for 16*2^20 = 16 MiB of input data. For longer messages the l value will be computed on the fly from the last table value, which will be a bit less efficient.
