In this paper we discuss our cryptanalysis of the Hagelin C38/48 (or M-209) cryptograms sent between Brussels and several Belgian officials in Congo immediately after the independence (1960-1961). This work was caxried out for the Belgian Parliamentary investigation committee (1999-2001) which investigated the circumstances of the murder on Patrice Lumumba. In the second part of the article, we try to extract the implications of this research on modern cryptology. We discuss the state of the art in cryptography and the research challenges that need to be addressed in the next decade.
