The algorithm takes as input a message of arbitrary length and produces as output a 128-bit fingerprint or 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.-The algorithm takes as input a message of arbitrary length and produces as output a 128-bit　fingerprint　or　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.
