8 * \brief MD2 Message-Digest algorithm.
10 * The algorithm takes as input a message of arbitrary length and produces
11 * as output a 128-bit message digest of the input.
12 * It is conjectured that it is computationally infeasible to produce
13 * two messages having the same message digest, or to produce any
14 * message having a given prespecified target message digest.
