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